ACT Guide: Complete Preparation for a Top Score
Published July 7, 2026 · 15 min read
The ACT is an alternative to the SAT for college admissions in the United States. While both tests are accepted by all US universities, the ACT has a different format and emphasis. This guide covers everything you need to prepare effectively.
ACT Format
The ACT has four sections: English (75 questions, 45 minutes), Mathematics (60 questions, 60 minutes), Reading (40 questions, 35 minutes), and Science (40 questions, 35 minutes). There is an optional Writing section (40 minutes). Composite score is the average of the four sections, scored 1-36.
Scoring
A composite score of 30+ is competitive for top universities. The average ACT score is approximately 20. Ivy League universities typically expect 33+. The ACT is known for its faster pace — you have less time per question than on the SAT.
Preparation Strategies
English
Focus on grammar, punctuation, sentence structure, and rhetorical skills. Practise identifying errors in context.
Mathematics
Covers pre-algebra, elementary algebra, intermediate algebra, coordinate geometry, plane geometry, and trigonometry. The ACT allows a calculator for all questions.
Reading
Four passages: prose fiction, social science, humanities, and natural science. Practise reading quickly and identifying main ideas and details.
Science
The Science section tests data interpretation, research summarisation, and conflicting viewpoints — not specific science knowledge. Practise reading graphs and tables quickly.
