The Question Every Singapore Student Asks
“Should I take the ACT or SAT?”
“Which one is easier?”
“Can I just take both?”
I’ve had this conversation hundreds of times with Singapore students and parents. And here’s the truth: neither test is objectively easier.
But one will almost certainly be easier for you specifically based on your strengths, weaknesses, and test-taking style.
I’ve worked with students who scored 1350 on the SAT and 33 on the ACT practice tests (equivalent to ~1450 SAT). I’ve also seen the reverse — students who excel on the SAT but struggle with the ACT’s pace.
This comprehensive comparison shows you exactly how the two tests differ, which one matches your strengths, and how to make the right choice for your university applications.

ACT vs SAT: The Big Picture Comparison
Let’s start with a high-level view.
| Feature | ACT | SAT |
| Total time | 2 hrs 55 min (3 hrs 35 min with Writing) | 3 hours (3 hrs 50 min with Essay) |
| Number of sections | 4 mandatory + 1 optional | 2 mandatory + 1 optional |
| Sections | English, Math, Reading, Science, (Writing) | Reading/Writing, Math, (Essay) |
| Science section | Yes | No |
| Calculator on all Math | Yes | No (only on one Math section) |
| Score range | 1–36 (composite) | 400–1600 (total) |
| Questions | 215 (without Writing) | 154 (without Essay) |
| Time per question | ~49 seconds average | ~70 seconds average |
| Reading passages | 4 passages, 40 questions | 5 passages, 52 questions |
| Math topics | Up to trigonometry | Up to advanced algebra/trig |
| Penalty for guessing | None | None |
First major takeaway: The ACT has more questions in less time. The SAT gives you more time per question but fewer questions overall.
Section-by-Section Breakdown
Let’s compare each section in detail.
📘 English (ACT) vs Reading and Writing (SAT)
ACT English:
- 75 questions in 45 minutes
- 36 seconds per question
- Tests grammar, punctuation, rhetoric, and style
- Embedded in 5 passages
- Straightforward grammar rules
SAT Reading and Writing:
- 54 questions total (combined) in 64 minutes
- 71 seconds per question
- Reading: 52 questions, passage-based comprehension
- Writing: Grammar and editing within passages
- More emphasis on evidence-based answers
Key differences:
| Aspect | ACT English | SAT Reading/Writing |
| Pacing | Very fast | More relaxed |
| Grammar difficulty | Moderate, rule-based | More contextual |
| Passage complexity | Medium | Higher (especially Reading) |
| Question style | Direct | Often requires inference |
Which is easier?
- ACT English is easier if: You know grammar rules well and can apply them quickly
- SAT is easier if: You’re a strong reader who thinks carefully about context and meaning
For Singapore students: Most find ACT English easier because Singapore’s English curriculum emphasizes grammar and rules, which aligns with ACT’s approach.
📐 Math (ACT) vs Math (SAT)
ACT Math:
- 60 questions in 60 minutes
- 60 seconds per question
- Calculator allowed for ALL questions
- Topics: Pre-algebra through trigonometry
- More geometry (circles, triangles, coordinate geometry)
- Some trigonometry (SOH CAH TOA, basic identities)
- Questions arranged from easy to hard
SAT Math:
- 58 questions in 70 minutes
- Two sections: No Calculator (20 min, 15 questions) + Calculator (55 min, 43 questions)
- Less geometry, more algebra
- Emphasis on problem-solving and data analysis
- Some advanced topics (quadratics, exponentials, rational expressions)
- Questions not strictly arranged by difficulty
Key differences:
| Aspect | ACT Math | SAT Math |
| Calculator use | All questions | Only second section |
| Geometry | ~30-35% | ~10-15% |
| Trigonometry | Basic trig | Minimal trig |
| Algebra | Moderate focus | Heavy focus |
| Word problems | More straightforward | More complex scenarios |
| Formulas provided | None | Some formulas given |
Which is easier?
- ACT Math is easier if: You’re strong in geometry and trig, prefer using a calculator, like straightforward problems
- SAT Math is easier if: You excel at algebra, can do mental math quickly, prefer deeper conceptual problems
For Singapore students: This is mixed. Singapore math curriculum is rigorous in all areas, giving students an advantage on both. However, students who struggle without calculators may find ACT Math more comfortable.
📖 Reading (ACT) vs Reading (SAT)
ACT Reading:
- 4 passages, 40 questions in 35 minutes
- 8 minutes 45 seconds per passage
- Passage types: Prose Fiction, Social Science, Humanities, Natural Science
- Always appears in same order
- Questions follow passage order
- More straightforward, detail-focused questions
SAT Reading:
- 5 passages (including 1 paired passage), 52 questions in 65 minutes
- 13 minutes per passage
- Passage types: Literature, History/Social Studies, Science (includes charts/graphs)
- Questions require more analysis
- Evidence-based questions (“Which lines best support your answer?”)
- More inference and synthesis required
Key differences:
| Aspect | ACT Reading | SAT Reading |
| Time pressure | Extremely high | Moderate |
| Question difficulty | Moderate | Higher |
| Passage complexity | Moderate | High (especially historical docs) |
| Question types | Direct comprehension | Evidence-based, analytical |
| Charts/graphs | None | Sometimes included |
Which is easier?
- ACT Reading is easier if: You read quickly, prefer straightforward questions, can skim effectively
- SAT Reading is easier if: You read carefully, enjoy analytical thinking, can handle complex texts
For Singapore students: ACT Reading is often harder because of brutal time pressure. Many Singapore students are careful, thorough readers — which the SAT rewards but the ACT punishes.
🔬 Science (ACT) vs No Equivalent (SAT)
ACT Science:
- 40 questions in 35 minutes
- 6–7 passages with graphs, charts, experiments
- Tests data interpretation, not science knowledge
- Three passage types: Data Representation, Research Summaries, Conflicting Viewpoints
SAT:
- No dedicated Science section
- Some science passages appear in SAT Reading
- Some data interpretation in Math section
Key difference:
The ACT has a separate Science section that tests your ability to read charts, interpret experiments, and compare scientific viewpoints. The SAT embeds these skills across Reading and Math.
Which is easier?
- ACT is easier if: You’re comfortable with charts/graphs and can process data quickly
- SAT is easier if: You prefer not having a time-pressured science reasoning section
For Singapore students: This is highly individual. Some students love the Science section because it doesn’t require deep science knowledge. Others panic at the data overload and time pressure.
Timing and Pacing: The Biggest Difference
Let’s look at time per question across both tests.
| Section | ACT Time/Question | SAT Time/Question |
| English/Writing | 36 seconds | 47 seconds (Writing) |
| Math | 60 seconds | 75 seconds (with calc), 80 seconds (no calc) |
| Reading | 52 seconds | 75 seconds |
| Science | 52 seconds | N/A |
The ACT gives you 30–40% less time per question on average.
This is the single biggest difference between the tests. If you’re a fast, instinctive test-taker, the ACT suits you. If you’re methodical and careful, the SAT may be better.
Scoring Systems: ACT 1–36 vs SAT 400–1600
ACT Scoring
- Each section scored 1–36
- Composite is the average of all four sections
- Science counts equally with English, Math, Reading
- Writing (if taken) scored separately, doesn’t affect composite
SAT Scoring
- Two sections: Evidence-Based Reading and Writing (200–800), Math (200–800)
- Total score is the sum of both sections (400–1600)
- Essay (if taken) scored separately, doesn’t affect total

Which Test Suits Singapore Students Better?
Singapore students have unique academic strengths:
✅ Strong in math (rigorous curriculum)
✅ Solid grammar foundation (structured English education)
✅ Good with data and charts (science curriculum)
✅ Disciplined study habits
✅ Used to high-pressure exams
But also some common challenges:
❌ Reading complex literary texts under extreme time pressure
❌ Speed over depth (Singapore exams often reward careful thinking)
❌ Unfamiliar with American historical documents (SAT Reading sometimes includes founding documents)
Typical Patterns I See
Singapore students who prefer ACT:
- Strong in geometry and trigonometry
- Fast test-takers
- Comfortable with data interpretation
- Prefer shorter, direct questions
Singapore students who prefer SAT:
- Excellent at algebra and problem-solving
- Careful, methodical thinkers
- Strong vocabulary and reading comprehension
- Prefer more time per question
At Test Prep with The Princeton Review Singapore, students take diagnostic tests for both ACT and SAT before committing to one — the data always reveals which test suits them better.
Real Student Scenarios: ACT vs SAT Choices
Case 1: Wei Jie — The Fast Processor
Strengths: Quick mental math, strong grammar, loves charts and data
Weaknesses: Gets impatient with long passages, dislikes multi-step word problems
Diagnostic scores:
- ACT: 31 (English 33, Math 32, Reading 29, Science 30)
- SAT: 1380 (EBRW 680, Math 700)
ACT equivalent of 1380 SAT: ~29
Recommendation: Focus on ACT. His natural speed and data skills suited the ACT better.
Final ACT score after prep: 33
Case 2: Priya — The Careful Thinker
Strengths: Deep reading comprehension, loves algebra, excellent at spotting patterns
Weaknesses: Slower reader, doesn’t like time pressure, makes careless mistakes when rushed
Diagnostic scores:
- ACT: 28 (English 30, Math 31, Reading 24, Science 27)
- SAT: 1410 (EBRW 710, Math 700)
ACT equivalent of 1410 SAT: ~31
Recommendation: Focus on SAT. Extra time per question suited her thinking style.
Final SAT score after prep: 1480
Case 3: Marcus — The Balanced Student
Strengths: Good all-around student, no major weaknesses
Weaknesses: No particular strengths either
Diagnostic scores:
- ACT: 30
- SAT: 1400 (equivalent to ~31 ACT)
Recommendation: Slight preference for SAT based on higher diagnostic, but could succeed with either.
Strategy: Prepared for SAT but took one ACT as well to maximize options.
Final scores: SAT 1460, ACT 32 — submitted SAT to most schools, ACT to schools that preferred it.
Should You Take Both Tests?
Short answer: Maybe, but it’s usually unnecessary.
When taking both makes sense:
✅ Your diagnostic scores are nearly identical on both tests
✅ You have time for separate preparation for each
✅ Your target schools have different testing preferences (rare)
✅ You want insurance against a bad test day on one exam
When taking both is inefficient:
❌ One test shows a clear advantage (2+ point ACT equivalent difference)
❌ You have limited preparation time
❌ You’re already juggling school exams and other commitments
❌ You’re aiming for top scores and need focused preparation
Most students should:
- Take diagnostic tests for both ACT and SAT
- Compare scores using concordance tables
- Identify which test suits your strengths
- Commit to ONE test and prepare thoroughly
- Take multiple attempts of that one test to maximize score
How to Decide Which Test Is Right for YOU
Follow this decision-making framework:
Step 1: Take Diagnostic Tests for Both
Use official practice tests:
- ACT: Download from act.org
- SAT: Download from collegeboard.org
Take each under real timed conditions. No breaks, no phone, strict timing.
Step 2: Convert Scores to Compare
Use the concordance table above to convert your ACT score to SAT equivalent (or vice versa).
Example:
- ACT diagnostic: 28
- SAT diagnostic: 1360
- ACT 28 = ~1300 SAT
- Conclusion: SAT shows 60-point advantage (about 2 ACT points) → focus on SAT
Step 3: Analyze Section Strengths
Look deeper than just composite/total scores.
| If you scored better on… | Then… |
| ACT English vs SAT Writing | ACT may suit you |
| ACT Math vs SAT Math | ACT may suit you |
| ACT Reading vs SAT Reading | ACT may suit you |
| ACT Science was comfortable | ACT advantage |
| SAT felt less rushed overall | SAT may suit you |
Rule of thumb: If you score 2+ points higher (ACT) or 60+ points higher (SAT) on one test, focus on that test.
Step 4: Consider Your Testing Style
Answer these questions honestly:
- Do you work better with time pressure or more thinking time?
- Do you prefer direct questions or analytical questions?
- Are you stronger in geometry/trig or algebra/problem-solving?
- Do you love or hate interpreting charts and data?
- Do you read quickly or carefully?
Your answers will point you toward the right test.
Common Myths About ACT vs SAT
❌ Myth 1: “The ACT is easier”
Truth: Neither is easier overall. Each suits different students.
❌ Myth 2: “Top universities prefer the SAT”
Truth: All US universities accept both equally. No preference.
❌ Myth 3: “The SAT tests smarter skills”
Truth: Both tests measure college readiness. Neither tests “intelligence” — they test learned skills.
❌ Myth 4: “You should take both to maximize chances”
Truth: Quality preparation for one test beats mediocre preparation for two tests.
❌ Myth 5: “The ACT Science section requires science knowledge”
Truth: ACT Science tests data interpretation, not biology or chemistry content.
Tutor Pro Tips for Choosing Your Test
🎯 Pro Tip 1: Trust the Diagnostic Data
Your diagnostic scores reveal more than your gut feeling. Don’t choose based on which test “sounds easier” — choose based on your actual performance.
🎯 Pro Tip 2: Consider Your Prep Timeline
If you have only 2–3 months to prepare, focus on ONE test. If you have 6+ months, you could explore both — but most students still benefit from focusing on one.
🎯 Pro Tip 3: Check Your Target Schools
While 99% of schools accept both, verify your specific universities. Some scholarship programs may have test preferences.
🎯 Pro Tip 4: Don’t Switch Tests Mid-Prep
If you’ve been preparing for the ACT for 2 months and suddenly want to try the SAT, you’re resetting progress. Commit to your choice unless there’s strong data-driven reason to switch.
🎯 Pro Tip 5: Remember Score Choice
Both ACT and SAT allow you to choose which test dates to send to universities. You can take either test multiple times and only report your best scores.
FAQs: ACT vs SAT for Singapore Students
Q: Do Singapore schools teach to the ACT or SAT?
Neither specifically. Singapore schools teach strong foundational skills that apply to both tests, but students need test-specific preparation.
Q: Is one test more accepted in the US than the other?
No. All accredited US universities accept both ACT and SAT equally.
Q: Can I send both ACT and SAT scores to universities?
Yes, but it’s usually unnecessary. Send whichever score is higher based on concordance tables.
Q: Which test is better for merit scholarships?
Both are treated equally. Focus on achieving the highest score on whichever test suits you better.
Q: Does the ACT Science section give an advantage to science students?
Not necessarily. ACT Science doesn’t test science content knowledge — it tests data interpretation, which any student can learn.
Q: If I’m applying to engineering programs, should I take the ACT?
Either test works for engineering. Choose based on your personal strengths, not your intended major.
Final Thoughts: There’s No Universal Answer — Only Your Answer
Here’s what I want you to remember.
The question isn’t “Which test is easier?”
The question is “Which test is easier for ME?”
And the only way to answer that question is with data from real diagnostic tests.
Take both diagnostics. Compare your scores. Analyze your strengths. Consider your test-taking style. Then commit to one test and prepare thoroughly.
The students who score highest aren’t the ones who chose the “easier” test. They’re the ones who chose the right test for their strengths and prepared strategically.
You now have all the information you need to make that choice. Go take those diagnostics.
