The SAT and ACT are standardized tests commonly used by colleges and universities in the United States to assess a student’s readiness for college-level work. Both exams measure skills in areas such as reading, writing, and math, and some versions of the ACT include a science section. While not all colleges require these tests, many still consider them as part of the admissions process, scholarship eligibility, or academic placement. Taking the SAT or ACT can help students demonstrate their strengths and expand their college opportunities.
