Covered on the exam
ACT Science (enhanced ACT, 2025 — this section is now OPTIONAL) — 40 multiple-choice questions in 40 minutes across passages in three formats: Data Representation (graphs/tables), Research Summaries (experiments), and Conflicting Viewpoints (competing hypotheses). Tests interpretation and reasoning, NOT memorized science facts. Reported as a 1–36 section score.
Data Representation
reading graphs and tables · interpolation and extrapolation · identifying trends
Research Summaries
experimental design · comparing results across trials · identifying variables
Conflicting Viewpoints
comparing two or more hypotheses · identifying points of agreement/disagreement · evaluating evidence for a viewpoint
ACT Science rewards students who've seen the question patterns, not just the definitions. Budget half your prep for recall and half for applying concepts to scenarios.
Before you study anything, know where you stand. You'll get a readiness signal, a weakest-unit callout, and an estimate of hours to ready. No signup.
Don't re-watch content you already know. Drill the 1-2 units flagged as weak. Exam-format flashcards + MCQs give you the question patterns, not just terms.
Simulate the real exam under time pressure. Miss it, and you'll know exactly which unit to revisit.
