SAT is the most widely used college admission test.
The SAT score is between 400 - 1600. SAT was redesigned in March 2016, and score now consists of the sum of 2 sections:
Superscore is best of Evidence-Based Reading and Writing test score and best of Math test score—and then calculate a “super composite” or superscore based on these scores.
Many schools (and the common application) will ask you to list this score.
