If you are not quite sure which test to take, then you have not done enough homework on the schools to which you are applying. To determine which test to take, you need to see what test scores your schools of interest will accept. Though the SAT is more widely accepted, some schools require ACT test scores, while others will accept scores from either test. Be sure to check if you will need to supplement either SAT or ACT scores with SAT II subject test scores. If you are applying to a multitude of schools your best bet is to take both the SAT and the ACT tests to cover all bases.

Selective schools use these scores to determine acceptance along with grades, class rank and extra curricular activities, colleges use SAT scores to determine whose application to accept or reject. Colleges that receive more applications than they can accept can afford to be more selective and tend to rely heavily on SAT scores. In that regard, SAT scores do matter if you are set on attending a selective or top rated school.

Differences between the SAT and the ACT though both the SAT and the ACT help colleges assess your academic accomplishments, the two tests are structured a bit differently from each other. The ACT measures scholastic proficiency in English, mathematics, reading, and science, while the SAT focuses on logic and reasoning in math, critical reading and writing tests. The ACT has an optional Essay question, whereas the SAT has a mandatory essay question.

As expected, the tests have their own scoring methods. The ACT awards up to 36 points for a given section and the SAT awards points up to 800 per section. The SAT also subtracts partial points for incorrect answers, and the ACT does not.
