Built around the eight units that actually move your AP Calculus AB score.
AP Calculus AB hinges on three big ideas — limits, derivatives, and integrals — but the score breakdown is dominated by Units 4 and 5 (analytical applications of derivatives and contextual rates of change). Our coverage front-loads those units with worked examples drawn directly from released CB free-response prompts, so the first time you see 'a particle moves along the x-axis…' you've already done it twice.
Most students lose points on AP Calc AB not because they can't compute a derivative, but because they can't translate an English-language scenario into the right setup. Every interactive lesson here ends with a translation drill: a short word problem, the model setup, and a step-by-step rubric so you can self-grade against the AP scoring guide.
154+ interactive lessons, diagnostic assessments, flashcards, daily questions, and competitive challenges — everything you need to score a 5.
Step-by-step lessons covering limits, derivatives, integrals, and all AP Calc AB topics with practice problems.
Quick assessment across all Calc AB topics to identify your strengths and weak areas with AP score prediction.
Drill a single AP unit at a time. 6 units · 4 different variations each — perfect for end-of-unit review.
Review derivative rules, integral formulas, theorems, and key AP Calculus AB concepts.
Challenge other students in real-time calculus battles — derivatives, limits, and integrals.
