The SATs and the ACTs are the two different tests that students are required to take for admittance to an American university. The SAT is primarily for use by students who wish to apply for college-level programs in the United States. The ACT is also used by many colleges in the US as well as Canadian universities.
The main purpose of these tests is to help admissions officers assess applicants’ skills and knowledge levels. In order to get into any college or university in the United States, you need to take these tests.
International students who want to study in the US at the undergraduate level, they can apply for admission without taking SAT or ACT. But the majority of colleges require students to take them before the admission process begins. If you decide not to take these exams, you will need an official letter from your school stating that you were exempt from taking these exams due to specific reasons or because of disability status if that is true.
