SAT vs ACT: Which Test Should You Take?
Every four-year college in the US accepts both the SAT and ACT equally. There’s no advantage to one over the other in admissions. The right test is simply the one where you score higher relative to the test’s scale. Here’s how to decide.
Side-by-Side Comparison
| Feature | SAT (Digital) | ACT |
|---|---|---|
| Total score range | 400-1600 | 1-36 (composite) |
| Sections | Reading & Writing (combined), Math | English, Math, Reading, Science, optional Writing |
| Time | 2 hours 14 minutes | 2 hours 55 minutes (3:30 with Writing) |
| Questions | 98 | 215 |
| Time per question | ~1 min 22 sec average | ~49 sec average |
| Math calculator policy | Calculator allowed on all math | Calculator allowed on all math |
| Math content | Algebra-heavy, some advanced math, data analysis | Broader — includes more geometry and trigonometry |
| Science section | No dedicated section (data analysis in Reading/Math) | Yes — tests graph/data interpretation, not science knowledge |
| Format | Adaptive digital (difficulty adjusts based on Module 1 performance) | Linear (same difficulty for everyone) |
| Score release | ~2 weeks | ~2-8 weeks |
| Cost | $68 (fee waivers available) | $68 without Writing, $93 with (fee waivers available) |
| Offered | 7 times/year | 7 times/year |
Which Test Favors Which Student?
Take the SAT If You:
- Excel at algebra and data analysis — SAT math is heavily weighted toward algebra, linear equations, systems, and word problems with data tables
- Prefer adaptive testing — the SAT adjusts difficulty based on your performance in Module 1, which can feel less overwhelming
- Want more time per question — SAT gives roughly 40% more time per question than ACT
- Are comfortable with the digital format — SAT has been fully digital since 2024
- Dislike science-style passages — no dedicated science section
Take the ACT If You:
- Are strong in geometry and trigonometry — ACT math covers a broader range of topics including more geometry
- Read quickly and efficiently — ACT requires much faster reading across all sections
- Enjoy or don’t mind data interpretation — the Science section tests reading graphs and experimental design, not science facts
- Want a straightforward, predictable format — linear test, same difficulty for everyone
- Are aiming for a specific superscore composite — some schools superscore the ACT (taking highest section scores across test dates)
The Decision Method: Take a Practice Test for Each
This is the only reliable way to decide. Don’t guess based on personality — take a timed practice test for both and compare.
How to compare scores:
| SAT Score | Equivalent ACT Score |
|---|---|
| 1600 | 36 |
| 1530-1560 | 35 |
| 1490-1520 | 34 |
| 1450-1480 | 33 |
| 1400-1440 | 32 |
| 1350-1390 | 31 |
| 1310-1340 | 30 |
| 1260-1300 | 29 |
| 1220-1250 | 28 |
| 1170-1210 | 27 |
| 1130-1160 | 26 |
| 1090-1120 | 25 |
Use the College Board’s official concordance table for exact conversions.
Where to take free practice tests:
- SAT: Bluebook app (College Board’s official practice) — full adaptive format
- ACT: ACT.org offers free full-length practice tests
Take both within the same week to minimize preparation bias. Compare converted scores. Go with whichever is 2+ points higher on the ACT scale (or 40+ points on the SAT scale).
Test-Optional: Should You Submit?
As of 2026, many selective colleges remain test-optional, but the trend is shifting back. MIT, Georgetown, Purdue, and others have reinstated requirements. Even at test-optional schools, submitting strong scores helps.
Submit if:
- Your score is at or above the school’s 50th percentile
- Your GPA is slightly below the school’s median (strong test scores compensate)
- You’re applying for merit scholarships (many require scores)
Don’t submit if:
- Your score is below the school’s 25th percentile
- Your GPA and extracurriculars are strong enough to stand alone
- Testing causes extreme anxiety that affects other parts of your application
Rule of thumb: At test-optional schools, 40-60% of admitted students still submitted scores. Students who submit strong scores have higher admit rates. If you can score well, submit.
Preparation Strategy
Timeline
| When | What |
|---|---|
| Sophomore spring | Take a practice SAT and ACT to decide which test to focus on |
| Summer before junior year | Start prep (2-3 months of consistent study is enough for most students) |
| Fall of junior year | Take PSAT/NMSQT in October for SAT practice + National Merit eligibility |
| Spring of junior year | Take official SAT or ACT (March-June) |
| Fall of senior year | Retake if needed (last chance for most application deadlines) |
Prep Resources
| Resource | Cost | Best For |
|---|---|---|
| Khan Academy SAT Prep | Free | SAT fundamentals, personalized practice |
| ACT Academy | Free | ACT practice from the test maker |
| Official practice tests | Free | Both SAT (Bluebook) and ACT (ACT.org) |
| Princeton Review / Kaplan | $100-$1,500+ | Structured courses with instructors |
| Private tutoring | $50-$200/hour | Targeted improvement on weak sections |
For most students: 2-3 months of consistent free prep (Khan Academy or ACT Academy) plus 3-4 full practice tests is sufficient. Don’t overspend on prep courses unless you’ve plateaued with free resources.
Key Takeaways
- Take a practice test for both — compare converted scores — go with the higher one
- SAT favors algebra-strong students who like more time per question
- ACT favors fast readers who are comfortable with broader math and data interpretation
- Even at test-optional schools, strong scores help — submit if above the 50th percentile
- 2-3 months of free prep is enough for most students
