The short answer: two or three
There is no limit on how many times you can take the SAT, and colleges do not penalise multiple attempts. In practice, most students find that two or three sittings capture almost all of their improvement. The first sitting removes test-day novelty; the second usually shows the gain from targeted preparation; a third makes sense when one section is still below your practice-test level and your colleges superscore.
Why the first retake helps the most
Students typically gain the most between the first and second sitting, often 30–80 points, because the first attempt exposes what actually goes wrong under real conditions: pacing, nerves, a content area you thought you knew. The Digital SAT’s adaptive structure adds a specific lesson: being careful on Module 1 decides whether you get the harder Module 2, and that is a habit you learn by doing it once.
When to stop
Stop when your official scores match your practice-test average. If your last three official practice tests and your last sitting are all within about 30 points of each other, another sitting will most likely land in the same place. Time spent on a fourth attempt is usually better spent on essays, activities and grades.
Planning the dates
A common pattern is spring of junior year (March or May), then August or October of senior year. That leaves a full summer for preparation between them and gets scores back before regular-decision deadlines. Use the score predictor after each practice test to see whether the gap to your target is closing, and the improvement guide to decide what to work on between sittings.
