ACT Preparation — frequently asked questions
What is the difference between the SAT and the ACT?
The SAT (digital) has two sections: Math and Reading & Writing. The ACT has four sections: English, Mathematics, Reading and Science Reasoning, plus an optional Writing essay. The ACT Science section tests data interpretation and experimental reasoning, not science knowledge. Both are accepted by all US universities. Students often score better on one than the other — taking a practice test for both helps identify which to pursue.
What is ACT Science Reasoning?
ACT Science is not a test of science knowledge — it is a data interpretation test. Students interpret graphs, tables and research summaries and answer questions about experimental design, data trends and conflicting viewpoints. Strong IGCSE or IB science students typically find it accessible if they understand the format.
What ACT score is competitive for top US universities?
Composite scores of 34–36 are in the top 1%. Scores of 32–33 are competitive for selective universities (top 25 nationally). Many strong programmes admit students with 30+ composite scores. Individual section scores matter too — weak scores in any section may flag to selective admissions offices.
