SAT vs ACT: Key Differences and How to Choose the Right Test

If you’re a high school student (or parent of one) gearing up for college admissions, you've likely asked: “Should I take the SAT or the ACT?” While both exams are accepted equally by colleges across the U.S., the right test for you depends on your strengths, learning style, and future goals.

Let’s break down the key differences — and help you make an informed decision.

Content Differences

  • Reading:

    SAT reading often features older or more literary texts. ACT reading is more straightforward but faster-paced.

  • Math:SAT leans toward algebra and data analysis, with more multi-step word problems. ACT includes a broader mix — including more geometry and trigonometry.

  • Writing/English:Both test grammar and sentence structure. The ACT English section is more direct and predictable.

  • Science (ACT only):This section doesn’t require specific science knowledge — instead, it tests how well you interpret charts, graphs, and experiments.

Timing & Pacing

One of the biggest differences is time pressure:

  • SAT allows slightly more time per question across all sections.

  • ACT requires faster pacing — especially on the Reading and Science sections.

If you process information quickly, ACT might be a better fit. Prefer time to think? The SAT might feel more manageable.

Who Should Take Which?

Consider the SAT if you...

  • Are stronger in algebra than geometry/trig

  • Prefer a slower pace

  • Do well with graphs, charts, and evidence-based reading

  • Like using Desmos — it’s built into the digital SAT!

Consider the ACT if you...

  • Are a fast reader and test taker

  • Enjoy science or interpreting data

  • Have a strong grasp of geometry and trigonometry

  • Want an optional science score for STEM programs (coming soon to ACT online)
