What makes the difference between ACT and SAT?
The ACT 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, but required by most colleges, measures skill in planning and writing a short essay. The test is administered in one session of three hours and thirty minutes including the essay.
The SAT Reasoning Test measures critical thinking skills students need for academic success in college. Primarily in multiple-choice format, the three sections of the SAT are Critical Reading, Math and Writing. The mandatory essay is always the first section of the three-hour and forty-five minute testing session. The SAT Subject Tests are one-hour tests in specific subjects measuring knowledge of particular subjects and the ability to apply that knowledge. Many universities require or recommend one or more of these tests for admission or for placement – determine the requirements of colleges under consideration.
