The SAT and SAT Subject Tests are a suite of tools designed to assess your academic readiness for college. These exams provide a path to opportunities, financial support and scholarships, in a way that's fair to all students. The SAT and SAT Subject Tests keep pace with what colleges are looking for today, measuring the skills required for success in the 21st century.
The ACT is a national college admissions examination that consists of subject area tests in English, mathematics, reading and science. The ACT Plus Writing includes the four subject area tests plus a 30-minute Writing Test. ACT results are accepted by all four-year colleges and universities in the U.S.
The ACT includes 215 multiple-choice questions and takes approximately 3 hours and 30 minutes to complete, including a short break (or just over four hours if you are taking the ACT Plus Writing). The actual testing time is 2 hours and 55 minutes (plus 30 minutes if you are taking the ACT Plus Writing).
