Why AP prep is different

AP exams have prerequisites.
Most prep pretends they don’t.

01

Concepts depend on each other

You can’t integrate a function you haven’t differentiated. You can’t balance a redox equation without understanding oxidation states. AP Mastery tracks which prerequisite is missing and surfaces it before the downstream concept.

02

The exam tests application, not recall

AP exams don’t ask you to recite definitions. They ask you to apply concepts in novel contexts. Knowing it when explained is completely different from applying it independently under time pressure.

03

Coverage without mastery is wasted time

Most AP prep covers everything. AP Mastery covers what you haven’t mastered yet. When the evidence says you’ve mastered a concept, we move on. No review of things you already know.
