ACT Mastery diagnoses exactly which skill is costing you points across English, Math, Reading, and Science — then builds a practice plan around only those gaps.
All four sections covered from day one. No credit card required.
English tests grammar and rhetorical strategy. Reading tests comprehension and inference analysis. A student can be strong in one and weak in the other. Most prep doesn’t distinguish them precisely enough.
ACT Science primarily tests data interpretation and experimental reasoning — not biology or chemistry. Students who study content are studying the wrong thing.
ACT Mastery tracks which skills you answer slowly and targets those specifically — not just which ones you get wrong.
A 22 in Math tells you nothing actionable. ACT Mastery tells you: polynomial operations are solid, trigonometry is your gap, and coordinate geometry is slow.
One account covers SAT Mastery and ACT Mastery. Run both diagnostics and see which test suits your skill profile before committing.
