SAT vs ACT

Comparison

SAT or ACT? Which Exam Should I Take? — 2025 Comparison

Quick Summary (TL;DR)

The SAT (1600-point scale, Reading & Writing + Math) and the ACT (36-point scale, English + Math + Reading + Science) are two different standardized exams. Every US university accepts both equally. Reading-heavy students tend to prefer the SAT, while fast test-takers strong in science lean toward the ACT. Research your target university's average admitted score and focus on the exam where you score highest.

Which One Is Right for You?

SAT is right for you if

Reading & Math focused

  • You are strong in Reading (long-passage reading + reasoning)
  • You want to use a calculator throughout all of the math
  • You are comfortable with adaptive testing (each correct answer makes the next question harder)
  • Fewer questions → each question carries more weight (60+ seconds/question)
  • You want a shorter exam

ACT is right for you if

Includes Science too

  • The Science section is an advantage for you — if you are a biology/physics/chemistry student
  • You are strong at thinking and answering quickly (high time pressure)
  • Trigonometry in Math comes easily to you
  • If you dislike the digital format, a paper alternative exists
  • You hold up well over a longer exam

Which exam is easier?

A common misconception: neither the SAT nor the ACT is 'easy.' The ACT is a race against the clock, while the SAT demands complex reasoning. It depends on your profile. According to ETS data, a 1500 SAT is roughly equivalent to a 34 ACT.

Which one do universities prefer?

All 4-year universities in the US accept both equally. Even STEM-heavy schools like MIT and Caltech accept the ACT just as readily as the SAT. Don't ask 'which one does my university want?' — it wants both.

Which is more advantageous for international students?

Many international students choose the SAT because: (1) it is more widely available through test centers such as IDP / British Council, (2) the Reading & Writing section aligns well with many national curricula, and (3) the absence of a Science section means less deviation from the standard curriculum.

Frequently Asked Questions

Can I take both the SAT and the ACT in the same year?▼
Yes — many students try both and apply with their higher score. Universities use the 'best score' or 'superscore'.
Does the ACT Science section require real science knowledge?▼
No. It measures your ability to quickly interpret the graphs, tables and experiment summaries provided. It tests reasoning, not specific scientific knowledge.
On which one is it easier to get a higher score?▼
It depends entirely on your profile. If you read fast and are strong in math, the ACT; if you are strong at long-passage reading + writing, the SAT.
What is a test-optional policy?▼
Many US universities (apart from Harvard, MIT, Princeton) apply a test-optional policy — they don't require an exam score. However, a high score strengthens your application.
