The SAT is a globally recognized college admission test that lets you show colleges what you know and how well you can apply that knowledge. It tests your knowledge of reading, writing and math — subjects that are taught every day in high school classrooms. Most students take the SAT during their junior or senior year of high school, and almost all colleges and universities use the SAT to make admission decisions.
The ACT test assesses high school students’ general educational development and their ability to complete college-level work.
The multiple-choice tests cover four skill areas: English, mathematics, reading, and science.
The Writing Test, which is optional, measures skill in planning and writing a short essay.
