A good SAT score depends on the colleges you are targeting, but nationally the average total sits near 1050, per College Board score data.
Scoring 1200 or higher generally places you above the 75th percentile, 1400 is competitive for selective universities (roughly the 95th percentile), and 1500-plus is highly competitive for the most selective institutions.
The most useful benchmark is a school's published middle-50% range: aim for the upper end of that range to strengthen your application.
Because many colleges are now test-optional and lean more heavily on your GPA, submit scores when they help rather than hurt your profile, and keep your classroom grades on track with a grade calculator so your academic record supports the rest of your application.
