SAT vs ACT: Which test should you take?
US universities accept the Digital SAT and the Enhanced ACT equally, with no admissions preference for one over the other. The right choice depends on which test format plays to your strengths.
This guide walks through the differences in 2026, with practical advice on how to decide.
We pride ourselves on being relationship-driven, walking alongside students and their families through the admissions process and continuing to celebrate their successes well into college and for years to come.
College admissions is an important milestone, and we’re honoured to help turn it into a journey of growth, discovery, and lasting impact.

This guide walks through the differences in 2026, with practical advice on how to decide.
SAT vs ACT at a glance
Both tests are computer-based, both are accepted at every US university that requires standardised testing, and both run internationally throughout the year. The differences come down to format, scoring, and section content.
How the Digital SAT works
Since March 2023 internationally, and March 2024 in the US, the SAT has been fully digital. Students take it on a laptop or tablet using the College Board's Bluebook app at an authorised test centre.
The Digital SAT has two main sections:
- Reading and Writing: two modules, 64 minutes total, scored out of 800
- Math: two modules, 70 minutes total, scored out of 800
Total testing time is around 2 hours 14 minutes, plus a short break. Section scores combine for a composite out of 1600.
The Digital SAT is adaptive: the difficulty of each section's second module depends on how the student performed in the first. Calculators are allowed throughout the Math section, with the Desmos graphing calculator built into Bluebook.
How the Enhanced ACT works
The ACT introduced significant changes from September 2025 (the ACT Enhancement) that made the test shorter and more flexible.
Under the current format, the ACT Composite Score is based on three core sections:
- English: 35 minutes, 50 questions, scored out of 36
- Math: 50 minutes, 45 questions, scored out of 36
- Reading: 40 minutes, 36 questions, scored out of 36
The Science and Writing sections are now optional. Each section is scored out of 36, with the composite (also out of 36) averaged from the core sections. Optional Science and Writing scores are reported separately.
Test length depends on which optional sections you choose:
- Core only (English + Math + Reading): around 2 hours 5 minutes
- Core plus Science: around 2 hours 45 minutes
- Core plus Science and Writing: around 3 hours 25 minutes
From February 2026, the ACT also has fewer questions and shorter passages overall. Internationally, the ACT is delivered in computer-based format at authorised test centres.
We generally recommend students take Science alongside the core sections, particularly for STEM applications. We don't usually recommend Writing unless a specific target university explicitly requires it.
SAT and ACT myths worth clearing up
Myth: Universities prefer one test
Both tests are accepted equally at every US university that requires standardised testing, including all Ivy League and elite schools.
Myth: There's a pass mark
Neither test has a pass/fail threshold. Scores are evaluated alongside grades, recommendations, essays, and extracurriculars as part of holistic admissions review.
Myth: Test-optional means scores don't matter
Many universities are now test-optional, but a strong score still strengthens an application; submitting a competitive score gives admissions teams an additional data point and can be particularly valuable for international applicants whose academic systems differ from the US.
How to decide between the SAT and the ACT
Most UK students decide which test to focus on by the end of Year 11 or early Year 12, leaving 9 to 18 months for focused preparation.
The clearest path is to try both:
1. Take a free full-length practice test for each (about 2 hours 15 minutes for the SAT, up to 3 hours for the ACT depending on optional sections).
2. Compare your current scores against typical thresholds for your target universities. A practice test shows where you are today, not where you'll end up; with focused preparation, students typically lift that score significantly before test day.
3. If you're still unsure, talk to a counsellor about your strengths, timeline, and target schools.
Extra time and accommodations
Students who receive extra time on UK school exams may be eligible for accommodations on the SAT or ACT, but the application processes differ between the two boards and can be complex. Plan well in advance, as accommodations approval typically takes several weeks. For detailed UK-specific guidance, see our SAT/ACT Accommodations article.
Your SAT vs ACT questions, answered
Neither test is objectively easier. Both are designed to be equally rigorous and are calibrated against the same percentile rankings. What matters is which format suits your individual strengths. Students who prefer shorter, discrete reading passages and a less time-pressured pace often gravitate to the SAT; students who are confident in science content and prefer immersive longer passages often prefer the ACT.
No. Every US university that requires standardised testing accepts both tests equally. Ivy League and similarly competitive universities have no preference. Submit whichever test you score best on.
For most students, no. Preparing for both spreads your time and energy thinly. We recommend choosing one, preparing thoroughly, and aiming for a strong score. The exception is students who genuinely score similarly on practice tests of both, in which case sitting one of each and submitting the higher score can be worthwhile.
For Ivy League and similarly competitive US universities, students typically aim for SAT scores of 1500+ out of 1600, or ACT composites of 33+ out of 36. For top-50 institutions more broadly, 1400+ SAT or 32+ ACT is a strong target. Both tests are weighted alongside academic record, essays, recommendations, and extracurriculars.
The SAT went fully digital internationally in March 2023, and in the US in March 2024. There is no longer a paper SAT outside of accommodations exceptions.
The ACT Enhancement took effect in September 2025. The Composite Score is now calculated from three core sections (English, Math, Reading), with Science and Writing optional. From February 2026, the ACT also has fewer questions and shorter passages overall.
Most UK students prepare for 3 to 9 months, depending on starting score and target. Students aiming for top-tier scores often start at the end of Year 11 with a foundation phase, then ramp into focused practice in Year 12.
There are around 25 SAT test centres across the UK, with the densest cluster in London and the South East. The ACT is offered at four UK centres, primarily in London. See our SAT Test Centres UK and ACT Test Centres UK pages for full details.
