ACT Science is really a misnomer. The test should be called the “reading with very confusing big words and tricky visuals” section. The reason ACT Science does not force you to memorize AP level Bio or complete IB Physics HL problems is that not everyone takes all of that math in high school. For ACT Science to be a fair standardized test for all high school students, the test asks you about basic science concepts in tricky or confusing ways.
If you're one of those people who runs away from Math and Science Questions or considers themselves a writer or artist rather than a scientist or mathematician, do not fear! You can still get a 36 on ACT Science.
