Updated February 2026 

Choosing between the SAT and ACT can feel overwhelming, especially when both tests are accepted by virtually every US university. The truth is, there’s no universally “better” test—only the test that’s better for you.

Both exams have undergone significant changes recently. The SAT moved to a fully digital, adaptive format in 2024, and the ACT rolled out its “Enhanced” version throughout 2025, making both tests shorter and more student-friendly than ever. This guide reflects those updates and will help you understand the key differences so you can make a confident decision.

Key Differences That Matter

Pace and Timing

This used to be a major differentiator—but not any more. Both tests have become significantly shorter and more manageable:

• SAT: 2 hours 14 minutes for 98 questions, giving you roughly 71 seconds per Reading & Writing question and 95 seconds per Maths question.
• ACT: 2 hours 5 minutes for 131 core questions. The enhanced format gives around 18% more time per question than the old ACT—roughly 42 seconds per English question, 67 seconds per Maths question, and 67 seconds per Reading question.

The SAT still gives more time per question overall, but the gap has narrowed considerably. Both tests now offer enough breathing room that pacing alone shouldn’t drive your decision.

Test Format and Delivery

The SAT is now exclusively digital, taken on a computer or tablet using the College Board’s Bluebook app. It uses multistage adaptive testing, meaning your performance on the first module of each section determines the difficulty of the second module. This means two students sitting side by side will likely see different questions.

The ACT offers both digital and paper options—you choose. Unlike the SAT, the ACT remains a linear test: every student gets the same questions in the same order, regardless of how they perform.

Mathematics Content

SAT Maths: 44 questions across algebra, problem-solving and data analysis, advanced maths, and some geometry and trigonometry. Calculator is permitted throughout (with a built-in Desmos graphing calculator). A reference sheet of formulae is provided.

ACT Maths: 45 questions covering a broader mathematical scope, including pre-calculus. Calculator is permitted throughout, but no formula sheet is provided. Maths answer choices have been reduced from five to four options.

Strong in advanced maths? The ACT might play to your strengths. Prefer algebra and having formulae provided? Consider the SAT.

Science Reasoning

SAT: No dedicated science section, though scientific concepts and data interpretation appear within Reading & Writing passages.

ACT: The Science section is now optional (fully rolled out as of September 2025). When taken, it tests interpretation of data, graphs, and experimental design—but it no longer counts towards the composite score. Instead, it contributes to a separate STEM score alongside Maths.

Our recommendation: If you’re applying to science, engineering, or medical programmes, we’d encourage you to take the optional Science section. It provides a STEM score that can strengthen your profile, and some universities may value seeing it.

Reading and Writing

SAT: The Reading and Writing sections are now combined into a single section featuring shorter passages (25–150 words), each followed by a single question. This is a significant departure from the old SAT’s lengthy multi-question passages. Questions focus on evidence-based reasoning, vocabulary in context, grammar, and rhetorical analysis.

ACT: English and Reading remain separate sections, each with shorter passages than previous versions. English focuses on grammar, usage, and rhetorical skills. Reading covers prose fiction, social science, humanities, and natural science passages with more straightforward comprehension questions.

Essay Component

SAT: No essay option (discontinued in 2021).

ACT: Optional 40-minute essay presenting your perspective on a contemporary issue.

Most UK students won’t need the essay component, but always check your target universities’ specific requirements.

How to Decide: A Practical Approach

Consider Your Academic Strengths

Consider the SAT if you…	Consider the ACT if you…
Excel at close reading and textual analysis Are stronger in algebra than advanced maths Like having formulae and a built-in graphing calculator Are comfortable with digital, adaptive testing Prefer shorter, self-contained passages	Want the flexibility of optional sections (Science, Writing) Are comfortable with advanced maths (trigonometry, pre-calculus) Prefer choosing between digital and paper formats Want a straightforward, non-adaptive question format Want to showcase STEM strengths with an optional Science score

 

Think About Your Test-Taking Style

Methodical and analytical? The SAT’s adaptive format and reasoning-heavy questions tend to reward students who enjoy working through problems carefully and considering evidence before answering.

Efficient and decisive? The ACT’s linear, curriculum-based approach can suit students who prefer to move through questions at a steady pace without second-guessing.

Anxious about technology? The ACT’s paper option may provide reassurance. That said, most students find digital testing intuitive after a couple of practice sessions.

Understanding Scoring and Superscoring

SAT Superscoring: Many universities will take your highest Reading & Writing score and highest Maths score across multiple test dates to create your best possible composite. The digital format delivers results within days rather than weeks.

ACT Superscoring: With the enhanced format, superscore composites are now calculated from your best English, Maths, and Reading scores (Science is excluded from the composite). Your highest section scores can come from any test event—whether taken under the old or new format.

Important note: While most universities superscore, policies vary. A small number of institutions (including Harvard) have indicated they will only superscore within the same ACT format version. Always verify individual university policies.

Both tests can be retaken multiple times, and most students see score improvements with targeted preparation between sittings.

Preparation Strategies

For the SAT

• Practice in Bluebook: The College Board’s Bluebook app offers official adaptive practice tests—essential for getting comfortable with the digital format and tools.
• Khan Academy: Free, personalised practice linked to the College Board.
• Focus areas: Reading comprehension, vocabulary in context, algebra, and evidence-based writing.
• Timeline: 3–6 months of consistent practice.

For the ACT

• Official ACT Prep: ACT has released updated practice tests reflecting the enhanced format.
• Focus areas: Advanced mathematics, shorter reading passages, and English grammar and rhetoric.
• Key decision: Whether to take the optional Science section (recommended for STEM applicants).
• Timeline: 2–4 months of intensive practice.

For Both Tests

1. Take your first practice test untimed to gauge content knowledge.
2. Then practise under timed, realistic conditions.
3. Focus on your weakest sections, but don’t neglect your strengths.
4. Take multiple full-length practice tests before the real thing.
5. Compare your SAT and ACT practice scores using official concordance tables to see which test gives you the stronger result.

Special Circumstances

Learning Differences

Both tests offer accommodations for students with documented learning differences, including extended time, separate testing rooms, large-print materials, and assistive technology. The digital SAT also includes built-in accessibility features such as text-to-speech options. Apply for accommodations well in advance through your school’s learning support department.

International Availability

Both tests are available internationally, but availability varies. ACT test centres can be less common outside the US, though the enhanced ACT’s digital option is expanding access. The SAT’s fully digital format means it’s widely accessible wherever you can bring an approved device. Check availability in your area when planning your test timeline.

Test-Optional Trends

While many universities adopted test-optional policies during and after the pandemic, there has been a notable shift back towards requiring or strongly recommending standardised test scores. Several highly selective institutions—including Yale, Dartmouth, and others—have reinstated testing requirements. Our strong advice: always submit a competitive test score if you can. Even at test-optional universities, a strong score meaningfully strengthens your application.

Making Your Final Decision

With both tests now shorter, more flexible, and more student-friendly, your choice should come down to personal fit. Here’s our recommended approach:

1. Take a practice test of each. Use official materials: Bluebook for the SAT, and the updated ACT practice test.
2. Compare your scores. Use official concordance tables to see which test produces the stronger result.
3. Consider comfort level. Which test felt more natural? Which format suited your working style?
4. Check your target universities. Verify any specific testing requirements or preferences.
5. Factor in logistics. Consider test dates, preparation time, and centre availability in your area.
6. Register early. Book at least 6–8 weeks in advance to secure your preferred date and location.

 

Remember: the “best” test is simply the one where you can achieve your highest score. Universities genuinely treat the SAT and ACT equally, so don’t overthink it—focus on finding the right fit for you.
