Acquire SAT Subject Test practice tests either online from sites such as College Board or at a bookstore and familiarize yourself with the types of questions that will appear on the exam. You can also contact your guidance counselor or career counselor for advice. According to the University of Texas Guide for Prospective Students, the SAT Subject Tests consist of multiple choice questions.
Familiarize yourself with all of the material from your notes from your classes and from your textbooks. The curriculum of your freshman, sophomore and junior years is intended to prepare you for the SAT Subject Tests. For example, the Math I and II Subject Tests each include 50 questions of material from algebra, geometry, trigonometry and statistics, according to the University Language Service website. The U.S. History exam, meanwhile, is designed to test your broader understanding of historical trends rather than simple memorization of names and dates.
Study one subject each day and take a different practice test each week to review the material. After you finish, check your answers; don't correct yourself during the test, as this takes up time.
Note which subjects you have the most difficulty with and focus on them first. Set aside a one-hour study period each day when you aren't taking a practice test.
Test yourself under timed conditions. This will acclimate you to the hour-long time limit used during the actual exams.
Focus on resting for the test for the last two nights beforehand. Avoid any last-minute cramming.
