TEST PREP
ACT Preparation
The ACT is an alternative to the SAT for US undergraduate admissions, accepted at every college that accepts SAT scores. Many institutions have moved to test-optional policies. Verify your target schools' requirements before preparing.
Who should consider ACT?
ACT is relevant for US undergraduate admissions at institutions that require or consider standardised tests. Confirm requirements before starting preparation.
Students applying to US universities that require a standardised test
All US colleges that accept the SAT also accept the ACT. If your target schools require a test, you can choose either. Compare both formats and sit the one that better suits your strengths.
Students with strong Science and analytical reasoning skills
The ACT includes a dedicated Science Reasoning section that does not appear in the SAT. Students who perform well in STEM subjects often find the ACT's section structure a natural fit.
Students applying to test-optional schools who want to strengthen their profile
Where test submission is optional, a strong ACT composite score can strengthen an application — particularly if your academic profile is otherwise competitive. Verify the score range for admitted students before submitting.
Students applying for merit scholarships that use ACT scores
Some scholarship programmes — both institutional and external — use ACT (or SAT) scores as part of their eligibility or ranking criteria. Confirm requirements with each scholarship separately.
What the test measures
Four sections scored 1–36 each. Composite is the average of all four section scores.
English
- Tests grammar, punctuation, sentence structure, and rhetoric
- 75 questions, 45 minutes
- Scored 1–36; contributes to the composite score
- Focuses on editing passages rather than isolated grammar rules
Mathematics
- Covers pre-algebra through trigonometry
- 60 questions, 60 minutes
- Scored 1–36; contributes to the composite score
- Calculator permitted throughout the entire section
Reading
- Passage-based comprehension across four genres: prose fiction, social science, humanities, natural science
- 40 questions, 35 minutes
- Scored 1–36; contributes to the composite score
- Tests literal and inferential comprehension — no external knowledge required
Science Reasoning
- Interprets data, research summaries, and conflicting viewpoints
- 40 questions, 35 minutes
- Scored 1–36; contributes to the composite score
- Does not require advanced science knowledge — tests data interpretation and analytical reasoning

Unique to ACT — not in SAT
When ACT makes sense
Your target US college requires standardised testing
All institutions that require the SAT also accept the ACT. If testing is required, compare sample questions from both tests before committing. The ACT's Science Reasoning section and time pressure per question differ meaningfully from the SAT.
You prefer the ACT format after comparing both tests
The ACT tends to be more content-based and straightforward in question style; the SAT emphasises analytical reasoning. Students with strong science backgrounds or those who prefer reading-based data analysis often score better on the ACT.
You are applying for scholarships that use ACT scores
Some merit scholarships use ACT scores as part of eligibility or competitive ranking. Check each scholarship's requirements — whether SAT and ACT are interchangeable or one is preferred.
You are applying 8–12 months before the deadline
ACT preparation typically requires 2–4 months for meaningful improvement. International students should verify test centre availability and registration deadlines in advance, as the ACT is less widely available outside the US than the SAT.
Preparation approach
1
Compare ACT and SAT before choosing
Take a short sample of each test before committing to either. The ACT has a Science Reasoning section, stricter time limits per question, and a different maths scope (including trigonometry). Your relative performance on the two tests — not a general preference — should drive the decision.
2
Take an official full-length practice test
ACT Inc. provides official practice tests at act.org. Take one under timed, full-test conditions to establish a reliable baseline composite score and identify which sections need the most work.
3
Prioritise time management on Reading and Science
Reading (35 minutes, 40 questions) and Science Reasoning (35 minutes, 40 questions) are where students most often run out of time. Practise section pacing from the start of your preparation, not only during full practice tests.
4
Review errors by category, not just by question
Categorise wrong answers by section and question type. ACT Science errors are often a pacing problem or unfamiliarity with data interpretation formats rather than scientific knowledge gaps. Address the actual root cause.
Common mistakes to avoid
Preparing for ACT without verifying that your target institutions actually require or benefit from a standardised test score
Choosing ACT or SAT based on general reputation rather than taking sample questions from both to assess your own relative performance
Underestimating the Science Reasoning section — it tests data interpretation, not science content knowledge, and requires specific preparation
Not practising with official ACT materials — unofficial mock tests may not reflect real section timing or difficulty accurately
Running out of time on Reading and Science sections — pacing is a distinct skill that requires deliberate practice
Submitting a below-median ACT score to a test-optional institution — this rarely helps and may weaken the overall application
Frequently asked questions
Is ACT accepted at the same colleges as SAT?
Yes. All US colleges that accept SAT scores also accept ACT scores. You do not need to submit both — choose one. Some students sit both tests and submit whichever score is stronger.
What is a competitive ACT score?
This varies significantly by institution. Highly selective US colleges typically report middle 50% ACT ranges of 33–36. Mid-tier universities may report ranges of 24–30. Research the reported score ranges for admitted students at each of your target institutions rather than targeting a single generic composite.
What is the Science Reasoning section?
Science Reasoning is a section unique to the ACT that does not appear in the SAT. It presents data tables, research summaries, and conflicting scientific viewpoints. It does not test specific knowledge of biology, chemistry, or physics — it tests your ability to read, interpret, and reason about scientific information. Students who are comfortable working with data and graphs often perform well with focused preparation.
Do international students still need IELTS or TOEFL if they take ACT?
Generally yes. The ACT is an admissions test, not an English proficiency test. Most US universities require a separate English proficiency test (IELTS, TOEFL, or DET, depending on the institution) from international students whose first language is not English, regardless of ACT performance. Confirm requirements with each institution.
How many times can I retake the ACT?
ACT can be retaken as many times as you wish. Most colleges that consider ACT scores will look at your highest composite score. Some schools superscore — taking the highest section scores across multiple sittings — but policies vary. Check each institution's approach to multiple ACT scores before deciding how many times to sit the test.
