Yes, ACT Science is mostly reading and data interpretation, not memorized science. The section tests whether you can read graphs, tables, and experiments and reason from them. Once you understand that, your whole prep approach can change for the better.
What the section actually asks
The vast majority of questions are answerable straight from the figures and passage. You'll identify trends, read data points, compare experiments, and interpret results. These skills are closer to Reading and Math than to a science class, and that's actually great news.
The small amount of outside knowledge
A handful of questions per test may assume very basic science (states of matter, simple biology, density). It's a minor share, so don't spend prep memorizing facts. Spend it on data skills instead.
Why this is good news
Because it's a reasoning section, you can improve quickly without relearning chemistry or physics. The fastest gains come from reading figures efficiently; see how to read graphs faster on ACT Science.
How to prepare accordingly
Treat Science like a data-and-reading section: go to the figures first, track variables and units, and practice spotting relationships. Build a repeatable method with the best ACT Science strategy.
The exception: conflicting viewpoints
One passage, Conflicting Viewpoints, is genuinely reading-heavy, with little or no data. Treat it like an ACT Reading passage: understand each viewpoint and compare them using textual evidence.
Practice the right skills
Drill data-interpretation passages on thirty-six rather than reviewing science textbooks. For the full plan, see how to improve your ACT Science score.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
