Lesson: Chapter - 13

Taking Advantage of the Test’s Regularity

Imagine an eleventh grader named Sylvie Pascal sits down at her desk and takes an SAT II Math IC practice test. Because it makes this example much simpler, imagine she takes the entire test and gets only one question wrong.

The question Sylvie missed dealt with parabolas—she had misidentified the vertex. Sylvie realizes she doesn’t have a firm understanding of how to graph parabolic equations, so she takes a few minutes to study up on coordinate geometry. She learns the basics of conic sections and what causes a parabola’s vertex to shift from the origin. All this takes about ten minutes, after which Sylvie vows never again to miss a question involving parabolas.

Analyzing Sylvie Pascal

Sylvie wasn’t content simply to see what the correct answer was and get on with her day; she wanted to see how and why she got the question wrong and what she should have done, or needed to know, to get it right. She spent a little time studying the question, discovered her mistaken understanding of parabola graphs, and learned the subject thoroughly. If Sylvie were to take that same test again, she definitely wouldn’t get that question wrong.

Skeptical readers might say, “But she’ll never take that test again, and she’ll never see that particular question again, so wasn’t figuring out her mistake a waste of time?”

No! It’s definitely not a waste of time. If you take the time to learn why you got a question wrong and to learn what you need to know to get it right, you’ll probably remember what you learned the next time you’re faced with a similar question. And chances are excellent that you will be faced with a similar question.

Sylvie and You

What if you take a practice test and get 15 questions wrong, and your errors span many of the major topics in math? Do exactly what Sylvie did. Take your test and study it. Identify every question you got wrong, figure out why you got it wrong, and then teach yourself what you should have done to get the question right. If you can’t figure out your error, find someone who can.

A wrong answer on SAT II Math IC identifies a weakness in your test-taking, whether that weakness is an unfamiliarity with a particular topic or a tendency to be careless. As you study each wrong answer, you are actually learning how to answer questions that will appear in similar form on the real SAT II Math IC. You are discovering your exact weaknesses and addressing them, and you are learning to understand not just the knowledge behind the question, but also the way that ETS asks questions.

True, if you got 15 questions wrong, studying your first practice test will take some time. But if you invest that time and study your practice test properly, you will be eliminating future mistakes. Each successive practice test you take should have fewer errors, meaning you’ll spend less time studying those errors. More important, you’ll be pinpointing what you need to study for the real SAT II Math IC, identifying and overcoming your weaknesses, and learning to answer an increasing variety of questions on the specific topics covered by the test. Taking practice tests and studying them will allow you to teach yourself how to recognize and handle whatever SAT II Math IC throws at you.
