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 mathematics. Designed and executed by the College Board, almost all colleges and universities in US use the SAT to make admission decisions for placements. Taking the SAT is the first step in finding the right college or university for you — the place where you can further develop your skills and pursue your higher education.
The redesigned SAT will be executed beginning March 2016 onwards by College Board. A small reformation has been done on its structure. The new structure follows:
4 parts: reading, writing and language, math, and the optional SAT Essay
400–1600 score scale
3 hours and 50 minutes with the SAT Essay — or 3 hours without the optional essay
4 answer choices
