This is something that you'll need to determine based on the school you're applying to. The vast majority of colleges do not prefer one test over another. However, if your prospective school does require a specific test, then you'll be left with no choice but to take that test. If your school does not require the ACT or SAT, you still have the option to complete and submit a test. This gives you the opportunity to choose the exam that best suits your abilities and prospective college major. The vast majority of colleges do not prefer one test over another. Which test you take should also depend on your career path. Below are some examples to consider. Science-focused majors: Unlike the ACT, the SAT does not have a dedicated science section. If you are seeking a career in the sciences, it may be beneficial to take the ACT over the SAT. Writing-intensive majors: The ACT also has a dedicated section, although optional, for writing. This area is meant to test how well you understand and evaluate complex problems and turn your assessments into thorough analysis. If you feel this may be an added benefit to your college admissions based on your major, then the ACT may be a better option. Math-focused majors: The SAT prohibits calculators on certain math questions, where you are required to show your work. Therefore, the SAT may be more appealing to math majors who are looking to test their skills in this area. Here are some other things to consider before choosing your test. The ACT costs $3 more for the basic test and another $15 for the essay portion. The ACT is also longer if you include the writing portion. Both tests allow you to use a calculator for the majority of the math portions.
