Take the SAT and/or ACT—If you feel like you can improve on your initial winter SAT and/or ACT results, take the SAT and/or ACT for the second time in the spring of junior year.
Take SAT Subject Tests for courses ending in the spring—SAT Subject Tests, which are required for some colleges, are best taken immediately after you’ve taken the relevant class and while the material is still fresh in your mind.
Take AP Exams—AP Exams, which provide an opportunity to earn college credit, are offered each year in May. If you need tutoring or extra help – get started in March for the May exam.
