Absolutely none. ZERO. The ACT “science” section doesn’t require any pre-existing knowledge of physics, chemistry, biology, or any other scientific discipline. It should really be called the ACT “comparing graphs and tables and using common sense” section. For instance, a question might ask, “during which year were mercury levels in X lake the highest?” Then they’ll show you a graph of fish deaths over multiple years in the lake, and explain that mercury leads to dead fish. Put two and two together and you have your answer. If you’re not a strong science student, don’t worry – the ACT requires zero actual science knowledge to master – just proper strategy.
