American College Testing — Complete Guide

The ACT (American College Testing), administered by ACT Inc., is a widely used US undergraduate admissions test accepted by every four-year college and university in the United States, alongside the SAT. Following a 2025 redesign the test is shorter, the Science section is now optional, and there is an optional Writing (essay) section. It is scored on a 1–36 composite scale.

Why ACT is important

🎓

US University Admissions

The ACT is accepted by all four-year US colleges and universities as an alternative to the SAT.

  • Accepted everywhere the SAT is
  • A strong composite (30+) is competitive for selective schools
  • Some students find the ACT format and pace suit them better than the SAT
🔬

Science Reasoning Option

The ACT is the test that offers a dedicated Science section (now optional), which can suit STEM-focused applicants.

  • Science tests data interpretation, not memorised facts
  • Useful signal for science and engineering applicants
  • Optional since the 2025 redesign — take it if your programme values it
💰

Scholarships

Many US universities and private scholarship programmes accept ACT scores for merit-based awards.

  • Widely used for merit scholarship eligibility
  • A high composite can unlock significant funding
  • Interchangeable with the SAT at most institutions
🌏

International Recognition

ACT scores are recognised by some universities outside the US as evidence of academic readiness.

  • Accepted by select institutions in Canada and beyond
  • Useful when applying across multiple countries
  • Results are reported on a clear 1–36 scale

How to prepare for ACT

1
Take a practice ACT and SAT
Both are accepted almost everywhere, so sit a timed practice test for each and take whichever suits your strengths and pace.
2
Master pacing
The ACT moves quickly. Practising under strict time limits is the single biggest driver of a higher score.
3
Use official ACT practice material
Free official practice questions and full-length tests are the most reliable preparation resource.
4
Decide on Science and Writing early
Since 2025 both are optional. Confirm whether your target universities want them before you register, and prepare accordingly.
5
Target your weakest section
Identify your lowest-scoring section from practice tests and give it the majority of your study time.

Frequently asked questions

ACT vs SAT — which should I take?
Both are accepted by virtually all US universities, so there is no universally "better" test. The ACT is slightly faster-paced and offers an optional Science section; the SAT leans more on evidence-based reasoning. Take a timed practice test for each and choose the one you score better on and feel more comfortable with.
Is the Science section still part of the ACT?
Since the 2025 redesign, the Science section is optional rather than a required part of the composite. Take it if your intended programme or university values a science reasoning score — check their requirements first.
How long is an ACT score valid?
Most US universities accept ACT scores taken within about 5 years. Always confirm the policy of the specific institutions you are applying to.
Can I take the ACT internationally?
Yes — the ACT is offered at authorised international test centres. International students register through the official ACT website, where availability and fees for your country are listed.
