SAT vs. ACT: Which Test Should You Take?

Do You Even Need to Take a Standardized Test?

Before diving into SAT vs. ACT, it's worth asking whether you need to take either. Many schools remain test-optional following the pandemic, and some have gone test-blind (meaning scores won't be considered even if submitted). Check the current policy for every school on your list — policies have been changing rapidly.

If a school is test-optional and your scores would hurt your application, don't submit them. If your scores are strong, submitting them can strengthen your application even at test-optional schools.

Key Differences Between the SAT and ACT

Both tests cover reading, writing, and math. The main differences:

• Science section: The ACT has a dedicated science section (data interpretation, not biology/chemistry knowledge). The SAT does not.
• Math: The SAT's math section is more heavily weighted and goes deeper into algebra and data analysis. The ACT math covers more topics (including some trigonometry) but at a shallower level.
• Timing: The ACT is faster-paced — more questions per minute. Students who work quickly tend to prefer the ACT; those who prefer more time per question often prefer the SAT.
• Essay: Both tests have optional essays that are rarely required by colleges.

How to Decide

Take a full practice test for both (available free at collegeboard.org and act.org) under realistic conditions. Compare your scores after converting to a common scale (concordance tables are available online). Most students perform similarly on both, but some have a clear preference based on the format and pacing.

How to Prepare Effectively

The most effective preparation is consistent practice with official materials. Khan Academy offers free, personalized SAT prep linked to your PSAT results. For the ACT, the official ACT prep guide is the most reliable resource. Third-party prep books vary in quality — stick to official materials first.

Practice under realistic conditions: full-length timed tests, no phone, at a desk. Reviewing your mistakes carefully is more valuable than doing additional practice without understanding why you got questions wrong.

How Many Times Should You Take It?

Most students see improvement from a first to second attempt, and some see improvement from a second to third. Beyond three attempts, the marginal benefit is usually small. Many colleges superscore (use your best section scores across attempts), which makes multiple attempts more valuable.
