Why misconception-targeted, not problem volume
Even in a calculus-based course, most AP Physics C: Mechanics points are lost to a small set of well-documented misconceptions: treating centripetal force as a separate physical force, sign errors in the work-energy theorem, misapplying the rotational analogs of Newton's second law, and confusing which moment of inertia belongs to a given axis.
If you hold a misconception, more practice with it intact reinforces it — the derivatives and integrals just sit on top of the same broken model. The fastest path from a 3 to a 4 is identifying which two or three misconceptions are costing you points and addressing them directly. That is what Mistake Master is built to do.
