How ACT suggests planning your ACT prep

  1. Look through Preparing for the ACT Test to see what each section covers.
  2. Take a practice test to find the subjects that are hardest for you.
  3. Spend most of your study time on those, and review the content areas that make up big parts of the test.
  4. Take another practice test under real timing to check you’ve improved.
