Should I take the ACT or SAT?

Most students select their preferred test as the first step in the test prep process and then prepare for that test exclusively. Both the ACT and SAT test for "college readiness". We recommend students take a practice test of each to obtain baseline scores, and then compare them to determine which test is the better option. Some students naturally do better on one of the tests, while other students earn comparable scores but prefer the content and timing of one of the tests.

You can compare your scores using the official Concordance Table published by ACT and the College Board.

When should I take my test?

The ACT is typically offered 7 times a year: September, October, December, February, April, June, and July. The SAT is also typically offered 7 times a year: August, October, November, December, March, May, and June. In 2020, there is also a September SAT scheduled.

Students taking the ACT often take it in February or April of junior year, with the option to take it again in June, July, or September. Students often take the SAT for the first time in March of junior year, with the option to retake it in May, June, August, or October. Because junior year is typically quite demanding, some students prefer to get an early start and take their tests in the fall or winter of junior year.


What is a good score?

While some students aim for a particular target score, others simply want to do the best they possibly can. Many colleges publish score data (such as the range, average, or 25th and 75th percentiles) of admitted applicants on their admissions websites. This gives you a sense of how your score compares to those of admitted students. Your official test score report will indicate your national percentile (e.g., if you score in the 80th percentile, that means you scored better than 80% of test takers). You can view official data on percentiles for the ACT and the SAT on their websites.


Should I take my test more than once?

Many students these days choose to take the ACT or SAT multiple times. Others take it just once. Many colleges "superscore" the SAT by considering the best score for each section across multiple test dates. Several colleges "superscore" the ACT. While some colleges request all test scores, others give students the option to select scores to send. Research your target schools to learn their specific requirements. Their admissions websites often explain if they superscore, offer score choice, or require the optional essay.


Will my official score report show which questions I answered incorrectly?

Students can receive standard score reports or order reports that provide details on the test they took. ACT offers Test Information Release (TIR) for the April, June, and December test dates, providing a copy of the ACT test questions, the student's answers, and the answer key. For the SAT, the College Board offers the Question and Answer Service (QAS) for the October, March, and May tests, providing a copy of the test the student took with a guide that gives correct answers and scoring information. The report shows the level of difficulty of each question, along with the student's answers. For other test dates, they offer the Student Answer Service (SAS), a report with information on the types of questions, their level of difficulty, and whether the student's answers were correct, incorrect, or omitted. Students who plan to take either test more than once often find it helpful to know what they answered incorrectly.
