AP Calculus topics Nova covers

Pick any area below and Nova will walk you through it at your pace — explaining, asking questions, and checking your work until it clicks.

Limits & Continuity

Formal definitions, one-sided limits, and the IVT. Nova is patient with the epsilon-delta formalism when your class glosses over it.

Differentiation (power, chain, product, quotient)

Implicit differentiation and related rates — the FRQ topics that show up almost every year on AB.

Applications of derivatives

Optimization, linear approximation, and MVT justifications. Nova drills the 'show that' justification language examiners look for.

Integration (Riemann sums, FTC, u-sub, by parts)

BC students: Nova covers IBP, partial fractions, and improper integrals. She'll drill the tabular IBP trick until it clicks.

Series (BC only)

Taylor, Maclaurin, radius of convergence, and the Lagrange error bound. The highest-leverage BC topic — Nova spends extra time here.

Parametric, polar, vector-valued functions (BC)

Speed vs. velocity, arc length, and polar area. Nova shows you how to avoid the sign errors that burn BC students.

FRQ strategy & justification language

How to phrase a 'because f'(x) changes sign' justification to earn the mark. Most students lose points to wording, not math.

How Nova helps

AP Calc is 50% math and 50% communication — the FRQs ask you to justify your answer, and College Board readers have a very specific vocabulary they reward. Nova has graded thousands of released FRQs against the scoring commentary, so she knows exactly which words earn points: 'because', 'by the Fundamental Theorem', 'since f' is continuous on [a,b]'. When you submit an FRQ to Nova, she scores it the way a real reader would, then shows you which phrase you needed to write to earn the missed point. That's what turns a 3 into a 5.

Frequently asked

Does Nova cover both AB and BC?+

Yes — just tell her which exam you're taking and she'll scope the topics accordingly. She also handles the Calculus C (multivariable) extensions some schools teach.

Can Nova grade my FRQ against the rubric?+

Yes. Photograph or paste your FRQ response and Nova scores it point-by-point using the published College Board rubric and scoring commentary.

Is Nova good at series for BC?+

Series is one of Nova's strongest topics — she can generate unlimited convergence-test practice and walks you through Taylor error bounds more carefully than most textbooks.
