What is the ACT Diagnostic?

The ACT Diagnostic is a full-length ACT administered under real test conditions — the same timing, format, and question types you'll face on test day. At the end, you receive a composite score along with individual section scores for English, Math, Reading, and Science. Those results become the foundation for identifying exactly which subjects and skills to prioritize in your prep.

  • 2

    Timed under official test conditions

  • 3

  • 4
