SAT and ACT scores are standardized test results used for college admissions in the United States. The SAT is scored on a scale of 400 to 1600, while the ACT ranges from 1 to 36. These tests assess a student's readiness for college by evaluating skills in areas such as math, reading, and writing. Colleges and universities often use these scores as part of their admissions process, alongside other factors like high school grades and extracurricular activities. Many institutions have specific score requirements, and some may be test-optional, meaning students can choose whether to submit their scores.
