The strongest story in the dataset is engagement.
In the broad cohort of students who completed at least three full tests and 250 question attempts, 52.0% improved 10+ points and 29.2% improved 15+ points. When we tighten the lens to students who reached five tests and 500 question attempts, those figures climb to 61.5% and 35.6%.
That is exactly the kind of pattern you want from a serious prep platform. More exposure to full tests, more drilling, and more review do not just create activity. They create better odds of real score movement.
The same platform gets more compelling as students use more of it.
