In many cases students are not advised to take full advantage of the college entrance test opportunities available during the junior year.  In the present competitive admission climate, juniors are wise to sit for an administration of both the SAT and ACT, to gain familiarity with both tests and to have the fullest possible information for college planning.  Almost all college-bound students take one or the other of the two tests more than once, so trying both in Grade 11 gives the student obviously useful information about which test to retake and also about areas to focus on in follow-up test preparation.  Moreover, many juniors postpone the SAT Subject Tests until senior year who should take them for the first time late in the junior year.  Students taking advanced-level courses or who plan to apply to highly selective colleges will benefit themselves by using one of the spring test dates for Subject Tests, which can then be repeated in the fall of Grade 12 to improve scores.  In some cases students assume that a Subject Test is redundant if they will take the Advanced Placement examination in the same subject, when in fact preparing for an AP exam can significantly benefit the student taking the corresponding Subject Test.  As for the AP exams themselves, in my experience the most under-utilized is the English Literature and Composition exam, which allows test-takers flexibility in choosing literary examples from their own experience of studying literature and not strictly from texts dictated in the test questions.  Students who have done well in an English curriculum emphasizing literary criticism and critical writing should seriously consider taking the English Lit & Comp AP, along with any other AP tests for which their curriculum has prepared them.  The Subject Tests and AP exams are definitely not for all college candidates, but with a thoughtful testing strategy they can reward the student considering selective schools.
