Most students take the SAT during their junior or senior year in high school. At least half of all students take the SAT twice — in the spring of their junior year and in the fall of their senior year. Most students also improve their score the second time around.
For the SAT Subject Tests, most students take them toward the end of their junior year or at the beginning of their senior year. In general, you should take tests such as World History, Biology E/M, Chemistry or Physics as soon as possible after completing the course in the subject. Students tend to do better on other tests like languages after at least two years of study.
Students have the option to choose which scores you send to colleges. If you decide not to use Score Choice, all of your scores will be sent to your recipients. Students should still feel comfortable sending all scores, since most colleges consider a student’s best score.
