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. Taking the SAT is the first step in finding the right college for you — the place where you can further develop your skills and pursue your passions. But SAT scores are just one of many factors that colleges consider when making their admission decisions. High school grades are also very important. In fact, the combination of high school grades and SAT scores is the best predictor of your academic success in college.
