(Head of Math and Sciences,\u00a0Biology and Chemistry\u00a0tutor at The Edge Learning Center<\/a>)<\/p>\r\nThe College Board offers a range of <\/span>SAT Subject Tests<\/span><\/a> from English to Mathematics and Sciences, the aim of these tests being to showcase your strengths in a given subject, as many colleges use the results in admissions, and a good score can give you an edge over other candidates. \u00a0All the tests are one hour long and consist of multiple-choice questions scored in a range from 200-800, with scoring based on your total correct answers minus a fraction for every wrong answer. This blog will focus on strategies to help you tackle the SAT Chemistry Subject Test. <\/span>\r\n\r\n[caption id=\"attachment_4006\" align=\"alignright\" width=\"363\"]\"stoichiometry\"<\/a> Stoichiometry (Photo taken from Wikipedia)<\/em><\/span><\/a>[\/caption]\r\n\r\nThe <\/span>SAT Chemistry<\/span><\/a> Subject Test<\/span><\/a> will test you on a range of core chemistry concepts from the structure of matter to reaction types and <\/span>stoichiometry<\/span><\/a>. \u00a0It will analyze your skills of recalling concepts, applying them, and using them to determine knowledge from data either quantitative or qualitative. As previously mentioned, the test is an hour long, during which time you have 85 questions to answer and so less than a minute per question. \u00a0The following strategies will help you overcome any fear of limited time and excel at the taking this test. The first key thing to understand is that there are three sections to the test and that each section has a given type of question.\u00a0<\/span>\r\n\r\nThe first section contains questions that use your concept-definition knowledge; you are given five choices A-E of words or phrases that are followed by three to four questions. Each of these questions relates to the list and you need to choose one letter that would answer each question. There will obviously be only one correct answer, so you must choose the best answer for the given question. A key point is the answers can be used more than once: just because first answer is A does not mean that the answers to other questions cannot also be A. These questions make up the first 20-25 questions of the test and should be completed pretty quickly in first 10 minutes of test.<\/span>\r\n\r\n[caption id=\"attachment_4003\" align=\"aligncenter\" width=\"430\"]\"sat-chemistry-subject-test-sample-question-1\" SAT Chemistry Subject Test sample question from College Boar<\/a>d<\/em><\/span>[\/caption]\r\n\r\nThe second section is the most tricky part of the test: 16 True or False questions. With these questions, you are given two statements about an aspect of chemistry and you have to decide if each statement is true or false. The statements are separated with the word because as it is possible the first statement is caused by or affected by the second statement, this brings in the third oval Cause\/Effect (C\/E). C\/E can only be possible if both of the statements are True, yet just because they are both true does not automatically mean they are C\/E. The next odd thing is the numbering of these questions; they start at 101 onwards even though there are only 85 questions in the test. Do not worry about this; just make sure you fill in answers in the right set of ovals. These questions really test your knowledge of the concepts and their interlinking effects. \u00a0The best way to deal with these is:<\/span>\r\n

    \r\n \t
  1. First take each statement on its own and decide If they are True or False. If they are both True then move onto step 2.<\/span><\/li>\r\n \t
  2. Then, see if statement one is caused by statement two. If it is then fill in C\/E. <\/span><\/li>\r\n<\/ol>\r\nIf only one of these three points is assessed incorrectly, the whole question is marked as wrong, losing you a fraction of a point.<\/span>\r\n\r\n[caption id=\"attachment_4004\" align=\"aligncenter\" width=\"400\"]\"sat-chemistry-subject-test-sample-question-2\" SAT Chemistry Subject Test sample question from College Board<\/em><\/span><\/a>[\/caption]\r\n\r\nThe third section is made up of standard multiple-choice questions: a single question with five possible answers. Some of these may be linked to a set of data or a given reaction and so test your ability to analyze data. This section makes up anywhere from 40 to 50 of the questions on the test. \u00a0Aside from testing data analysis, this section will also examine your ability to apply concepts and problem solve. These questions are generally longer than the previous section and have to be read carefully, making their successful handling \u00a0a balance between managing timing and gaining key points. One of the main ways people lose marks is by not reading the word \u201cFalse\u201d or \u201cNot True.\u201d In this type of question, you are looking for the statement that is wrong and eliminating the other four, which will be true statements on the concept. In this case, there is no quick way to deal with it; you must read all five statements to ensure you don\u2019t fall into a trap answer. \u00a0<\/span>\r\n\r\n[caption id=\"attachment_4005\" align=\"aligncenter\" width=\"426\"]\"sat-chemistry-subject-test-sample-question-3\" SAT Chemistry Subject Test sample question from College Board<\/em><\/span><\/a>[\/caption]\r\n\r\nAlong with these ideas for each type of question, there are a few general strategies when preparing for the SAT Chemistry. First of all, do not panic. It is common to come across a question you can\u2019t answer straight away because nothing about the topic immediately comes to mind. Do not panic and waste time; skip it and move on. If your timing is right (part A 10 minutes, part B 15 minutes and part C 25 minutes), you will have time to come back to it later. \u00a0To get this timing right, this next point is important: take the easy questions first (as a general rule, the questions in each section get harder the closer to the end of the section). \u00a0Try to get these easy questions sorted first, and then double back to harder or skipped questions. One last thing that some students find useful is to make a glossary or flashcards of the key terms and definitions. These will help especially with the first two types of questions, but it is important to be flexible with the wording, as many questions will try to trick you with how they phrase a definition. <\/span>\r\n\r\nThese are just some basic strategies for the SAT Chemistry Subject Test.

      (Test Prep (ACT\/SAT\/SSAT), English Literature tutor at <\/span>The Edge Learning Center<\/span><\/a>)<\/span><\/p>\r\n\"sat-act-test-dates\"<\/a>Many of the students who come to The Edge for assistance with the<\/span> SAT<\/span><\/a> or the<\/span> ACT<\/span><\/a> do not realize that one of the most important factors for success is an intelligent testing plan. Unless you are one of the small minority of students who crushes the exam the very first time you take it, there\u2019s a good chance you will be sitting for the SAT\/ACT a few times during your high school career. Making sure that you are prepared for these brushes with standardized testing is a great way to ensure success, minimize anxiety, and put yourself on the fast track to university admissions. Seeing as the SAT is offered <\/span>six times each year<\/span><\/a> in Hong Kong and the ACT is only offered <\/span>five times a year<\/span><\/a>, a question naturally arises: <\/span>\u201cwhen should I take these tests?\u201d<\/b>\r\n\r\nBefore you start getting worked up about your test date, your first step is to make sure that you are prepared for the levels of math in each examination. Both the SAT and the ACT require that you have a good grasp of the fundamentals of geometry, algebra, and trigonometry. Most students will have encountered all of these topics by the beginning of their junior year, <\/span>making 11<\/b>th<\/b> grade an ideal choice for beginning a test preparation schedule<\/b>.<\/span>\r\n\r\n\"CollegeAlthough this next step may seem somewhat backwards, it is usually more helpful to think of the last possible examination that you can take. If you are part of the majority of students who are only applying Regular Decision in the college admissions process, you will have to adhere to RD application deadlines (which are usually in January or February of senior year). Consequently, the last SAT\/ACT test date viable for most RD deadlines is the one in <\/span>December<\/b>. If you know that you will be applying Early Decision or Early Action, then your last test will typically fall in <\/span>October<\/b>. The application deadlines for specific universities vary, however, so you should always make sure you have enough time.<\/span>\r\n\r\nSo now it\u2019s the start of junior year. You think you\u2019ll be applying Regular Decision, but you\u2019re not sure yet. What should you do?<\/span>\r\n

      1.) Take the<\/span> SAT in January<\/span> or the<\/span> ACT in December<\/span><\/span><\/h2>\r\nLet me make one thing clear: <\/span>you should not go into this test unprepared<\/b>. A test preparation course like <\/span>The Edge\u2019s SAT\/ACT Essentials<\/span><\/a> would assist you with both knowledge of the test and the test\u2019s content, but if this is not your style, then make sure that you take at least a few practice tests to familiarize yourself with the way the test works. \u00a0While your first exam will probably not be your last, there\u2019s a distinct (if slight) chance you could get the score you\u2019ve always dreamed of. If you beat the odds and get this score, then you\u2019re totally done! For the rest of us, this test score will serve as a good benchmark with which we may best plan our upcoming test schedule.<\/span>\r\n

      2.) Take the<\/span> SAT in June\/May<\/span> or the<\/span> ACT in June<\/span><\/span><\/h2>\r\nBoth tests are available in June, but the ACT is not offered in May. This test is the big one for most juniors, and your performance here should be informed by a sustained, serious amount of studying. As you reflect on your performance on your first exam, you should seek to strengthen the content areas that you struggle with most so that you can crush this one. Whether you schedule 1-on-1 lessons with a private tutor or self-study, you need to be approaching your peak ability. \u00a0If you succeed, you\u2019re done! You can chuckle at all your friends\u2019 stress levels! If you don\u2019t, your friends might chuckle at you, but don\u2019t worry; there are a couple more chances to get the score you want.<\/span>\r\n

      3.) Take the<\/span> SAT in October<\/span> or the<\/span> ACT in September\/October<\/span><\/span><\/h2>\r\nYour summer needs to be sincerely devoted to improving your SAT\/ACT score. By senior year, your plate will be full of extracurricular activities, schoolwork, college applications, and (hopefully) a social life, but if you\u2019ve not yet gotten your SAT\/ACT scores up to where you want them, it will be very difficult to balance all of these things. This is the third test you will have taken, and it will hopefully be your last. If you are applying to Early Decision\/Early Action, this is the last possible test you can use. If you are applying Regular Decision, you have one more shot.<\/span>\r\n

      4.) Take the<\/span> SAT in November\/December<\/span> or the<\/span> ACT in December<\/span><\/span><\/h2>\r\nThis is it. This is the last one. If you\u2019ve not achieved the score you want by this time, kiss your social life goodbye. To make sure that your standardized test scores do not hold you back from the college of your dreams, you need to work as hard as possible to succeed on this one. Relinquish your dream of dominating your school\u2019s annual badminton competition, tell your friends to leave you alone, and put off a little bit of homework for school; the SAT\/ACT doesn\u2019t wait for anyone, and it will drive right past you. <\/span>\r\n\r\nSo there you have it! This is an ideal testing schedule for about 90% of Hong Kong students. It will allow you a decent number of opportunities to see and correct the errors you make, four different opportunities to take the test, and ample time to engage in rigorous test preparation. Students who are well-prepared for these exams most often do exceedingly well on them; students who are ill-prepared do not. You and your parents already know which one you want to be.<\/span>\r\n\r\n\"Good<\/a>","excerpt":"\u00a0\u00a0By Levi Busch (Test Prep (ACT\/SAT\/SSAT), English Literature tutor at The Edge Learning Center) Many of the students who come to The Edge for assistance with the SAT or the ACT do not realize that one of the most important factors for success is an intelligent testing plan.

      By <\/b>Steve Leech<\/b><\/a><\/h3>\r\n

      (Test Prep (ACT\/SAT\/SSAT), English Literature, English Builder tutor at The Edge Learning Center<\/a>)<\/p>\r\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span> In my experience, a major issue a lot of students have with literature is that they overthink it and get intimidated. To simplify, I often tell them to consider the idea of <\/span>privilege<\/span><\/i>: which people have social power, where it comes from, and what its effects are. This concept forms a useful lens for understanding many literary theories such as feminism, marxism, queer theory, and the topic of discussion here, postcolonialism.<\/span>\r\n\"Britain<\/a><\/span>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span> Postcolonialism examines the impact of a foreign colonial or imperial presence on a local population, whether it\u2019s the British and the Native Americans, the British in India, or the British across pretty much half of Africa. Other colonial powers have existed, of course, but the British got into colonialism like it was Crossfit.<\/span> Naturally, one can look at any aspect of a culture from a postcolonial (\u201cPoCo\u201d if you\u2019re hip) perspective, but applying it to literature is especially valuable for the IB curriculum, which often asks students to consider international literature or poses culture-based questions on the Paper 2 examination.<\/span>\r\n\r\n \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span> Much postcolonial literature from the 20th and 21st centuries deals with the immediate effects of European meddling in Africa, Asia, and the Americas (such as in Chinua Achebe\u2019s <\/span>Things Fall Apart<\/span><\/a>) all the way up to how events two or three generations ago affect people today (as in Zadie Smith\u2019s <\/span>On Beauty<\/span><\/a>.)<\/span>\r\n\r\n \u00a0\u00a0\u00a0\u00a0\u00a0\"the_bluest_eye<\/a>\u00a0\u00a0<\/span> Throughout these texts, postcolonial issues extend beyond obvious matters like the forced relocation of slaves or the economic exploitation of indigenous people to more intimate questions. In Toni Morrison\u2019s novel <\/span>The Bluest Eye<\/span><\/a>, African-American characters hold themselves to white European standards of beauty, which leads them to much suffering and self-harm. A central idea in many of these works is cultural\u2013and therefore personal\u2013identity. The value curricula such as the IB place on these types of perspectives is that they push students to consider perspectives outside of what they themselves encounter daily or, especially in the case of students in Hong Kong, to reexamine those daily encounters with fresh eyes. Even students who never experienced life in British Hong Kong live in its shadow.<\/span>\r\n\r\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span> Even so, these types of relationships between cultures are far from a recent phenomena. We can take PoCo back hundreds of years to when the people of the British Isles were on the receiving end of imperialism for a change. <\/span>Beowulf<\/span><\/a> is one of the earliest known texts in the English language although you might not think so when you look at it. This narrative poem comes from the Geats, a people from what is now Sweden, but is written in English. Were the Geats trying to force their culture onto the local English people, or were the English actively taking elements of the Geats\u2019 culture for their own?<\/span>\r\n\r\n \u00a0\u00a0\u00a0\u00a0\u00a0\"lord-of-the-flies<\/a>\u00a0\u00a0<\/span> This is just one example of the breadth postcolonial perspectives can take. Certainly we can look at the indigenous people affected by empires and colonial powers, but we can also examine those same expansionist powers through the same lens to consider their values and drives. Rudyard Kipling\u2019s \u201c<\/span>The White Man\u2019s Burden<\/span><\/a>\u201d, about the struggle of white Europeans to bring \u201cculture\u201d and Christianity to the world, seems quite silly and sad in the light of William Golding\u2019s <\/span>Lord of the Flies<\/span><\/a>, which details the descent of western schoolboys into primitive savagery when they are removed from the general society.\u00a0<\/span>Similarly, <\/span>On Beauty<\/span><\/a> considers in part the effect that increased power and autonomy on the part of colonized people has on the traditional figure of colonization: the white European male. It does not go well.<\/span>\r\n\r\n \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span> While the postcolonial perspective is powerful and certainly useful in the IB curriculum<\/a>, it is far from the only philosophy that students can leverage to not only improve their scores but also better understand literature as a whole. Examining these social power structures opens the door to more subtle movements and philosophies, which in turn create a greater understanding of not only the written arts but also the greater experience of the human condition.<\/span>\r\n\r\n ","excerpt":"By Steve Leech (Test Prep (ACT\/SAT\/SSAT), English Literature, English Builder tutor at The Edge Learning Center) \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 In my experience, a major issue a lot of students have with literature is that they overthink it and get intimidated.

      It shoul\"normal-breakfast-the-edge-test-day-tips\"<\/a>d come as no surprise then that despite all the documentation out there on the subject, one of the most common questions we hear from our students as test day approaches is \u201cHow do I avoid test anxiety?<\/em>\u201d While the best way to avoid it is to be as prepared as possible, there are some other things you can do which will help to reduce the amount of stress you feel.<\/p>\r\n\r\n

        \r\n \t
      1. Eat a normal breakfast<\/strong> - In other words, do not change your eating habits just for the test. If you don\u2019t drink coffee regularly, don\u2019t start right before exam.<\/li>\r\n<\/ol>\r\n
          \r\n \t
        1. Get plenty of rest<\/strong> - Many students will stay up late worrying over the test, cramming for the test, or just relaxing and watching tv before the test. Avoid all of these and make sure you get at least 8 hours of rest the night before the exam.<\/li>\r\n<\/ol>\r\n
            \r\n \t
          1. \"wake-up-early-the-edge-test-day-tips\"<\/a>Wake up early <\/strong>- Try to give yourself plenty of time to prepare the morning of the test. The earlier you wake up, the less rushed you will feel. This will make you far more relaxed come test time.<\/li>\r\n<\/ol>\r\n
              \r\n \t
            1. Leave early <\/strong>- Give yourself the peace of mind knowing that you will arrive on time and not be rushed through the registration process. Plan on leaving 30 minutes before you would normally leave so that you can account for any unexpected delays in your commute.<\/li>\r\n<\/ol>\r\n
                \r\n \t
              1. Dress comfortably<\/strong> - Sometimes the rooms can be hot or poorly ventilated. Make sure you dress in layers in something which is very comfortable for you. There are few things more frustrating than being stuck\r\nin a hot room wearing an itchy sweater you can\u2019t take off.<\/li>\r\n<\/ol>\r\n
                  \r\n \t
                1. Bring the correct documents and tools<\/strong> - Ensure that you bring your sign-up form from the test vendor and your appropriate government ID. They will not allow you to take the exam if you forget these. Additionally, prepare your pencils and erasers the day before. We suggest that you actually pack these in a closed folder the night before so that you only need to remember to bring the folder.<\/li>\r\n<\/ol>\r\n
                    \r\n \t
                  1. Bring a watch <\/strong>- While they usually do have a clock for you to look at, having your own watch can bring a sense of familiarity.<\/li>\r\n<\/ol>\r\n
                      \r\n \t
                    1. \"check-your-email-the-edge-test-day-tips\"<\/a>Check your email<\/strong> - You may be asking yourself why this one makes the list.

                      (Test Prep (ACT\/SAT\/SSAT), ESOL, English Builder, Latin\u00a0tutor at The Edge Learning Center<\/a>)<\/p>\r\nThe current version of the <\/span>SAT<\/span><\/a> now has a greater focus on math \u2013 800 of the total 1600 points compared to only 800 of 2400 previously \u2013 so scoring high on the math sections of the test is necessary for a good overall score. While there is no replacement for a solid fundamental knowledge of mathematical concepts, it\u2019s also important to realize that the SAT is (largely) a multiple choice test, and you can often use this to your advantage.<\/span>\r\n\r\n\"sat-math-test-prep\"<\/a>The SAT is different from your high school math tests: you don\u2019t get points for showing your work, there\u2019s no partial credit, and usually you simply have to pick the correct answer from a list of 4 choices. These differences can sometimes mean that a straightforward, algebra-based approach to solving difficult questions is not always the most efficient way forward. Let\u2019s look at a difficult algebra question from one of the practice exams provided by <\/span>Khan Academy<\/span><\/a>.<\/span>\r\n

                      \"fxgx\"<\/p>\r\nThe polynomials f<\/em>(x) and g<\/em>(x) are defined above. Which of the following polynomials<\/a> is divisible by 2x + 3 ?\r\n

                      A) h<\/i>(x) = f<\/i>(x) + g<\/i>(x)<\/span><\/p>\r\n

                      B) p<\/i>(x) = f<\/i>(x) + 3g<\/i>(x)<\/span><\/p>\r\n

                      C) r<\/i>(x) = 2f<\/i>(x) + 3g<\/i>(x)<\/span><\/p>\r\n

                      D) s<\/i>(x) = 3f<\/i>(x) + 2g<\/i>(x)<\/span><\/p>\r\nThis question seems rather intimidating, and many students won\u2019t really have a good idea of how to tackle it and find the correct answer quickly. The \u201cproper\u201d way to solve this question using fundamentals of algebra is to do the following: First, notice that <\/span>f<\/span><\/i>(x) can be rewritten with a common factor of 2x removed: \"fx\"<\/span>\u00a0Then, using <\/span>substitution<\/span><\/a>, rewrite <\/span>f<\/span><\/i>(x) as 2x <\/span>\u2022<\/span> g<\/span><\/i>(x). Finally, evaluate the answer choices with this substitution in mind, and notice that answer choice B, <\/span>f<\/span><\/i>(x) + 3<\/span>g<\/span><\/i>(x), becomes 2x <\/span>\u2022<\/span> g<\/span><\/i>(x) + 3<\/span>g<\/span><\/i>(x). Removing the common factor of <\/span>g<\/span><\/i>(x) leaves 2x + 3, which is the factor we\u2019re looking for.<\/span>\r\n\r\nLuckily, this is not the only way to answer the question. For algebra questions like this one with a variable in the question stem and the answer choices, it\u2019s often simpler to pick a real number for <\/span>x<\/span><\/i> and solve using actual numbers rather than variables.<\/span>\r\n\r\nSo let\u2019s pick a number for <\/span>x<\/span><\/i> and see if we can make this problem simpler. The domains of these functions are unrestricted, so we can choose any value we like for <\/span>x<\/span><\/i>. Let\u2019s make the math as easy as possible and just say <\/span>x<\/span><\/i> = 1. Plugging 1 for <\/span>x<\/span><\/i> into the functions defined by the question gives us the following:<\/span>\r\n

                      \"f1g1\"<\/span><\/p>\r\nNow we have real number values for <\/span>f<\/span><\/i>(x) and <\/span>g<\/span><\/i>(x). \u00a0The question wants to know which answer choice is divisible by 2x + 3, which is now 5 since we picked 1 for <\/span>x<\/span><\/i>: 2(1) + 3 = 5. If we substitute <\/span>f<\/span><\/i>(x) = 12 and <\/span>g<\/span><\/i>(x) = 6 into the answer choices, we\u2019re looking for a value that is divisible by 5.<\/span>\r\n

                      A) <\/span>h<\/span><\/i>(x) = <\/span>f<\/span><\/i>(x) + <\/span>g<\/span><\/i>(x) = 12 + 6 = 18 <\/span>\u2717<\/span><\/p>\r\n

                      B) <\/span>p<\/span><\/i>(x) = <\/span>f<\/span><\/i>(x) + 3<\/span>g<\/span><\/i>(x) = 12 + 3(6) = 30 <\/span>\u2713<\/span><\/p>\r\n

                      C) <\/span>r<\/span><\/i>(x) = 2<\/span>f<\/span><\/i>(x) + 3<\/span>g<\/span><\/i>(x) = 2(12) + 3(6) = 42 <\/span>\u2717<\/span><\/p>\r\n

                      D) <\/span>s<\/span><\/i>(x) = 3<\/span>f<\/span><\/i>(x) + 2<\/span>g<\/span><\/i>(x) = 3(12) + 2(6) = 48 <\/span>\u2717<\/span><\/p>\r\nOnly answer choice B, 30, is divisible by 5, so it must be the correct answer. <\/span>\r\n\r\nPicking a small number for <\/span>x <\/span><\/i>in questions like this can turn a seemingly unsolvable puzzle into nothing more complicated than simple multiplication and addition of small <\/span>integers<\/span><\/a>. While this kind of approach won\u2019t work on every SAT math question, it\u2019s always worth considering whether you can pick a number to simplify a difficult algebra problem.<\/span>\r\n\r\n\"you-can-do-it-sat-math-test-prep\"<\/a>","excerpt":"By James Rodkey (Test Prep (ACT\/SAT\/SSAT), ESOL, English Builder, Latin\u00a0tutor at The Edge Learning Center) The current version of the SAT now has a greater focus on math \u2013 800 of the total 1600 points compared to only 800 of 2400 previously \u2013 so scoring high on the math sections of the test is necessary […]","link":"http:\/\/theedge.com.hk\/test-prep-strategies-picking-numbers\/","category":"Edge Insights","catIcon":"http:\/\/theedge.com.hk\/wp-content\/uploads\/2014\/11\/announcement-logo.png","background":"http:\/\/theedge.com.hk\/wp-content\/uploads\/2015\/03\/JamesRodkey-300x221.jpg","date":"

                      \u00a01.\u00a0<\/strong>Memory and Learning\u00a0<\/strong><\/h2>\r\nStudents usually retain the large amount of content at the end of a lesson, as shown in Figure A. The amount of recall of the knowledge gradually reduces with time. This reduction is most likely due to the function of the brain in that the short-term memory<\/a> can only temporarily store the information. In order to strengthen the memory, we need to review what we have learnt so that the amount of information recalled can be held for a longer time and also clarify some points that making recall higher than before\u00a0 (Figure B). However, the amount of highest recall can be obtained with constant in time\u00a0 by strategic revision (Figure C). Thus, short-term memory transitions into long-term memory, which can store the information permanently in the brain. This movement to long-term memory<\/a> storage is the ideal outcome of learning for students.\r\n\r\n\"memory-graphs\"<\/a>\r\n
