College Admissions Calculators

Most US colleges accept either the SAT or ACT — you don't need both. The PSAT/NMSQT is taken in 10th or 11th grade as a practice test that also qualifies juniors for National Merit Scholarships. AP exams are subject-specific tests that can earn you college credit before you even arrive on campus.

SAT vs ACT. The SAT is adaptive (Module 2 difficulty changes based on Module 1 performance), shorter (2 hours 14 minutes), and uses a built-in Desmos calculator on all Math questions. The ACT is non-adaptive (everyone gets the same questions), longer if you take Science, and historically more straightforward in pacing. As of April 2025, the ACT made Science optional. Students who excel at adaptive testing and dense reading passages tend to favor the SAT; students who prefer predictable pacing and broader content coverage tend to favor the ACT. Take a full-length practice test of each — pick whichever you score better on.

Do I need to take the PSAT? If you're a junior aiming for National Merit Scholarships, YES — the October PSAT/NMSQT is the only qualifying test. If you're not chasing National Merit, the PSAT is still useful as a practice run for the SAT (same format, same scoring scale). Sophomores can take it for practice but cannot qualify for National Merit until they retake it as juniors.

Are AP exams required? No — AP exams are optional. They're taken to earn college credit (a 3, 4, or 5 typically qualifies for credit at participating schools) or to strengthen your college application by demonstrating academic rigor. Most selective colleges look favorably on AP coursework, but you don't need a specific number of APs to apply.

The most efficient testing path for a typical student aiming for selective colleges: PSAT in 10th grade (practice), PSAT/NMSQT in 11th grade (National Merit + practice), SAT or ACT in 11th-12th grade (admissions), and 3-5 AP exams across junior and senior year (credit + rigor signal). Use the calculators above to track your progress on each.

Every standardized college admissions test uses some version of raw score → scaled score conversion. Your raw score is the number of questions you got right. None of these tests penalize wrong answers, so always guess on every question.

Your raw score is then converted to a scaled score using a process called statistical equating. The test publisher adjusts the conversion for each specific test form so that scaled scores remain comparable across different test dates. A 1400 SAT in May 2026 means the same thing as a 1400 SAT in October 2025, even though the specific questions were different.

The SAT and PSAT now use Multi-Stage Adaptive Testing (MSAT). Your performance on the first module of each section determines whether you see harder or easier questions in the second module. The harder Module 2 lets you reach the maximum section score; the easier Module 2 caps your score around 600 (SAT) or 560 (PSAT).

The ACT is not adaptive — every test-taker gets the same questions on a given test date. Section scores are averaged into a composite, rounded to the nearest whole number.

AP exams combine multiple choice and free response into a composite percentage, then map to a 1-5 score using cut scores set each year. Cut scores account for exam difficulty — if a particular exam was harder than usual, the cut scores are adjusted downward.

The result: your scaled scores are meaningful across test dates and against other students, but the raw numbers behind them are not directly comparable.
