What are the best ACT Science prep books?

Answer 1

ACT Science doesn't really required to know scientific knowledge.

Basically, you need to practice to analyze given data and interpret it to find answer.

I recommend to use "Official ACT prep guide" (Red book) to start.

They have diagnostic test with 3-4 practice test. They also have score guide with answer explanation to help you see your level.

Hope this is helpful!
