How Are SAT Subject Tests Scored
How Are SAT Subject Tests Scored  SAT / ACT Prep Online Guides and Tips  Picture this: you sit down to take an SAT Subject Test. You answer somewhere from 50 to 95 questions in an hour. A few weeks later, you log on to your College Board account and see a score for your test on a scale of 200-800.Somehow, the results from your multiple-choice test got turned into this final scaled score. But how did this happen? How are SAT Subject Tests scored?  In this article, Iââ¬â¢ll discuss how your raw score for the exam is calculated, how this is converted into your final score, and what SAT Subject Test scoringmeans for youin terms of setting- and meeting- a target score.      How Is Your Raw SAT Subject Score Calculated?  Your raw score is your point total on the SAT Subject Test before itââ¬â¢s been converted to your final score on the 200-800 point scale. So if there are 60 questions, the highest raw score you could get would be 60.  However, unlike with the regular SAT, your raw score isnââ¬â¢t based only on how many questions you get right but also onhow many questions you get wrong.This so-called "guessing penalty," which was designed to discourage random guessing, means that for every question you get wrong, a fraction of a point will be deducted from your raw point total for questions youââ¬â¢ve answered correctly.  The point deduction for answering a given question incorrectlyis based on the number of answer choices for the question:    -1/4 pointper incorrect five-choice question      -1/3 pointper incorrect four-choice question      -1/2 pointper incorrect three-choice question      0 points per question left unanswered    Most questions on SAT Subject Tests are five-choice questions, so the guessing penalty is usually just a quarter-point.  Subject Test raw scores are rounded to the nearest whole point. In other words, half-points and above round up, while anything below a half-point rounds down. So a 33.25 would round down to 33, whereas a 33.5 would round up to 34.  Your raw score, then, can be expressed as follows:    # of answers right âËâ (# of answers wrong x guessing penalty) =  raw score (rounded to nearest whole number)    If, on a 60-question Subject Test such as Literature, you get 45 questions right, get five wrong, and leave 10 blank, your raw score would be as follows:    45 answered correctlyâËâ (5 answered incorrectly x 0.25 guessing penalty) =  45âËâ 1.25 = 43.75  43.75 rounded to the nearest whole number = 44  Raw score = 44 points    To recap: SAT Subject Test scoring is based on both how many questions you get right and how many you get wrong. Once that number is established, though, how does the College Board come up with your 200-800 point score? Read on to find out!      The College Board: a pictorial representation.    How Your Final SAT Subject Test Score Is Calculated  If you've been taking practice tests usingThe Official Study Guide to ALL SAT Subject Tests,you might have noticed that there is a chart for converting your raw score on a practice test to a scaled score after each practice exam.  These charts can give you a loose ballpark as to how a certain raw score on one test might convert to a scaled score from 200 to 800, but they're not exact. There is no consistent formula you can use to convert a raw SAT Subject Test score to a scaled score.  This is because the College Board equates scaled scores to make it so thatscores are comparable between different administrations of the test.Equating accounts for small difficulty variations and minor differences in the skill levels of test takers on different test dates.  Basically, your individual score wonââ¬â¢t suffer if the people who took the Subject Test with you were unusually strong in that subject. (On the flip side, your score won't be better, either, if the people who sat with you were unusually weak in the subject.)  In other words, a 650 from the Math II test you took in November willreflect the same level of masteryas Anyaââ¬â¢s 650 score on the Math II test next May. Even if your test administration was full of state math-team champions and hers had mostly people who failed geometry, neither of these factors will influence your final scaled scores!  Equating works to your advantage- you donââ¬â¢t want to have to worry about who else is taking the test the same day as you, or whether your edition of the test will be a little harder than usual.  I do not, unfortunately, know the witchcraft (and by witchcraft, I mean statistics) through which the equating process occurs. Nor could I learn, unless I had access to lots of secret College Board test data.  What I do have is some advice on how to approach the relationship between raw scores and scaled scores.

Setting a Target Scaled Score for an SAT Subject Test  To reiterate what we've gone over so far, each SAT Subject Test is equated to give you a final scaled score on a scale of 200-800. The SAT Subject Test score you should aim for ultimately depends on what scores the schools you're applying to are looking for.  To figure out what your goal score should be, look up the average or recommended SAT Subject Test scores of admitted applicants for each of your schools. For example, if you're applying to the Ivy League,this guide goes over the scores you should aim for on each Subject Test (depending on your major). You can also look up SAT score info on schools' official websites or contact schools' admissions offices and ask them what you should aim for.  Note that more and more schools merely recommend SAT Subject Test scores and don't require them. That said, if you're applying to a highly selective school, you should still try to submit Subject Test scores since a high score can greatly boost your chances of admission.  If you can't find exact score data for a school, estimate what score you'll need to get based on how selective the institution is.Competitive schools generally want to see SAT Subject Test scores in at least the 700s- sometimes 750+.  Once you've filled out your chart, look for the highest score on it. This will be your goal (scaled) score for that SAT Subject Test.Get this score, and you'll have an excellent shot at getting into all the schools you're applying to. In the example above, a perfect 800 would give you your best shot at getting into these top-tier schools.  But what raw score should you aim for on your SAT Subject Test?    How to Set a Target Raw Score for an SAT Subject Test  You might be wondering what raw score you should be targeting based on your target scaled score. Due to the equating process and variations among tests, thereââ¬â¢s no way to determine exactly what raw score you'll need in order to get your target scaled score. That said, there are ways to give you a rough idea.    Option 1: Consult Raw Score Conversion Charts in the Official Guide  For starters, if you have The Official Study Guide to ALL SAT Subject Tests(which I highly recommend if you're taking any Subject Tests!), you can flip to the raw score-scaled score conversion chart at the back of the practice test for your subject to geta decent approximation of what raw score you should be aiming for to get a certain scaled score.  For example, on the Literature test, you can see that a raw score of 55 out of 61 possible points converts to 770. Meanwhile, on Math Level II, 46 (out of a possible 50 raw points) converts to 800. And so on.  Here's an abbreviated conversion chart we've put together for those who don't have access to the official SAT Subject Tests guide. Though this chart will not work perfectly for every Subject Test, it should still be able to give you an estimated raw score to aim for:        Raw Score  Lit  US Hist  W Hist      95  -   -   800      90  -   800  800      85  -   800  800      80  -   800  800      75  -   770  780      70  -   730  750      65  -   700  720      60  800  670  690      55  770  650  670      50  730  620  640      45  690  600  610      40  650  570  580      35  610  540  560      30  570  520  530      25  530  490  500      20  490  460  470      15  450  440  440      10  410  410  410      5  370  390  380      0  below  200-330  230-360  220-360                Raw Score  Math I  Math II      50  800  800      45  760  800      40  720  760      35  670  700      30  620  650      25  580  610      20  510  580      15  470  540      10  430  500      5  390  460      0  below  250-350  300-410                Raw Score  BioE  BioM  Chem  Phy      85  -   -   800  -       80  800  800  790  -       75  780  790  760  800      70  750  760  740  800      65  720  730  710  800      60  690  700  690  800      55  670  670  670  770      50  640  640  640  730      45  610  620  620  700      40  580  590  590  670      35  550  560  570  630      30  520  530  540  600      25  480  490  520  560      20  450  460  490  530      15  410  420  460  490      10  370  390  430  460      5  340  350  400  420      0  below  220-320  240-330  270-370  270-390                  Languages-  Listening      Raw Score  Chinese  French  German      85  800  800  770      80  800  800  750      75  770  800  730      70  740  760  700      65  720  730  680      60  690  690  650      55  670  660  620      50  640  630  590      45  620  600  570      40  590  570  540      35  560  540  520      30  540  520  500      25  510  490  470      20  490  460  450      15  460  430  420      10  430  400  390      5  410  370  360      0  below  220-380  200-330  270-330                Languages-  Listening      Raw Score  Japanese  Korean  Spanish      85  -   -   800      80  800  800  780      75  770  780  740      70  730  750  700      65  690  720  650      60  640  690  620      55  600  660  590      50  560  630  550      45  530  600  530      40  490  570  500      35  460  540  470      30  430  510  440      25  400  480  410      20  370  450  390      15  340  410  360      10  300  380  340      5  270  350  310      0  below  200-240  200-320  200-280                  Languages -  Reading      Raw Score  French  German  Modern Hebrew      85  800  800  800      80  800  780  770      75  800  750  700      70  770  720  640      65  730  680  600      60  700  640  560      55  670  610  530      50  640  570  500      45  610  540  480      40  590  510  460      35  560  480  440      30  530  450  420      25  510  430  400      20  480  400  390      15  450  380  370      10  430  360  350      5  400  330  320      0  below  230-380  200-310  200-290                Languages -  Reading      Raw Score  Italian  Latin  Spanish      85  -   -   800      80  800  -   780      75  770  -   750      70  740  800  720      65  710  790  680      60  680  750  640      55  660  720  600      50  630  680  560      45  600  650  530      40  570  610  500      35  540  580  470      30  500  540  450      25  460  510  420      20  430  480  400      15  400  460  380      10  370  430  360      5  330  410  340      0  below  200-300  270-390  200-310            Raw veggies are just like raw scores- only greener.    Option 2: Use SAT Subject Test Percentiles  You can also check out the percentiles for all SAT Subject Tests.These tell you what percentile rank each scaled score corresponds to. They wonââ¬â¢t tell you the corresponding raw score, but you can still get a solid idea of how many questions you can afford to get wrong for a top score.

Let's take a look.  If an 800 is a 99th percentile score, as it is for Literature and Math Level I, the curve is going to be much steeper than it is for a test like Math Level II (in which an 800 is only a 79th percentile score). That means that to get an 800 on Math II, you have to score better than only 80% of test takers, while to get an 800 on Math I, you have to score better than 99% of test takers!  Basically, the higher the percentile number is for an 800 score, the fewer questions you can afford to get wrong for a score at the top of the range. This also means that a top score for these exams really stands out.    Option 3: Look at Average SAT Subject Test Scores  A final option is to look atthe average scores for each SAT Subject Test.Here's an overview of the current averages for each test:        SAT Subject Test  Average Score      Literature  607      US History  640      World History  622      Math Level I  605      Math Level II  693      Ecological Biology  618      Molecular Biology  650      Chemistry  666      Physics  667      Chinese with Listening  760      French with Listening  668      German with Listening  618      Japanese with Listening  703      Korean with Listening  761      Spanish with Listening  662      French  628      German  620      Modern Hebrew  612      Italian  666      Latin  626      Spanish  647        Source: The College Board  A high average score doesnââ¬â¢t necessarily mean the test is easy, though- it could also mean that the students who take it tend to have a high skill level in the subject. Moreover,on tests with high averages, it can be hard to differentiate yourself from the pack, so thatââ¬â¢s something else to keep in mind.  Overall, thereââ¬â¢s no secret way to know what raw score will correspond to a given scaled score when you sit down to take an SAT Subject Test. However, you can get a ballpark idea of how to meet your target scaled score by using official SAT conversion charts and recentpercentile rankings.      Stand out like the ballerina in the front.

Meeting a Target Raw Score on an SAT Subject Test  Due to the guessing penalty, meeting a raw target score isnââ¬â¢t as simple as answering a certain number of questions correctly. You also need to think about the points youââ¬â¢ll lose from incorrect answers.  The guessing penalty doesnââ¬â¢t mean that you should never guess if you arenââ¬â¢t completely sure of the answer. The more answer choices you can eliminate, the better your chances are of getting the right answer and avoiding the penalty.  Letââ¬â¢s go over the math. Most SAT Subject Test questions have five answer choices. Ifguessing randomly, you'll have a 20% chance of getting the question right. Thus, you would most likely get onein fivequestions correct if randomly guessing.  But if for every correct answer you get 1 point and for every four questions wrong you lose 0.25 points, this comes out to a penalty of 1 point per question.This means you'll net zero points! More importantly, though, it means youââ¬â¢ve wasted time. Clearly, random guessing is not a great strategy.  But what if you could eliminate one answer choice per question? Assuming youââ¬â¢ve eliminated the answer correctly, this gives you a slightly higher 25% chance of getting the question right, or an average of one in four questions right. In this case, you'll get 1 point for every correct answer and lose 0.25 points for every three questions, resulting in a penalty of 0.75 points per question. Thatââ¬â¢s a net of 0.25 points!  Is this really worth it, though? Remember that raw scores round to the nearest whole number, so if you're guessing on four questions, your 0.25 points wonââ¬â¢t help you go up a point- theyââ¬â¢ll just round back down. Unless you guess on eight questions with one answer choice eliminated per question, you are not likely to net any gains to your raw score this way.  Itââ¬â¢s a different story if you can eliminate two answer choices per question. If you guess on three five-choice questions and can eliminate two answers each for those questions, you'll have a 33% chance of getting each question right. Chances are, youââ¬â¢ll get one of those three questions right. Thatââ¬â¢s 1 point. Youââ¬â¢ll get penalized for your two wrong answers by 0.25 points each. Thatââ¬â¢s -0.5 points.  One point gained - 0.5 point penalty = a net of 0.5 points. Since raw scores are rounded to the nearest point, that adds a point to your raw score! Awesome. And your chances only go up the more answer choices you can eliminate.  Keep in mind that this is just probability. Depending on whether youââ¬â¢re lucky or unlucky, you could get better or worse results. But the math is definitely on your side for guessing if you can eliminate two or more answers. This will boost your raw score and help you meet your target score.    Key Takeaways: SAT Subject Tests Scoring  SAT Subject Test scoring is a little unusual because your score doesnââ¬â¢t just account for how many questions you answered correctly- it also includes deductions for questions you answered incorrectly.  Your raw score is calculated by subtracting the penalty for each question you got wrong from the points ofquestions you answered correctly, rounded to the nearest whole number.  The College Board then converts your raw score to a scaled score via a process called equating so that scores from different administrations of the test are comparable with each other.  Because of this, itââ¬â¢s hard to say with total certainty what raw score you'll need in order to hit a particular scaled score. That said, you can get a general idea using the conversion charts in The Official Guide to ALL SAT Subject Tests and the most recent Subject Test percentile rankings.  When you're trying to hit your target raw score, remember that on questions you aren't totally sure of, the more answer choices you can eliminate, the better your chances are of guessing the correct answer and avoiding a penalty.
