Prerequisite-aware sequencing across 13 AP STEM subjects. Every question calibrated to close your exact knowledge gaps.
Limits, derivatives, integrals, and the Fundamental Theorem — targeted to your gaps.
Series, parametric, polar, and advanced integration techniques with AB prerequisite awareness.
Exploring data, sampling, probability, and inference — with emphasis on interpretation.
Polynomial, rational, exponential, logarithmic, and trigonometric functions.
Cell biology, genetics, evolution, ecology — with lab-based reasoning practice.
Atomic structure, bonding, reactions, kinetics, thermodynamics, and equilibrium.
Ecosystems, biodiversity, pollution, and sustainability with data analysis focus.
Kinematics, dynamics, energy, waves, and circuits — algebra-based.
Thermodynamics, fluids, optics, electrostatics, magnetism, and modern physics.
Calculus-based mechanics: kinematics, Newton’s laws, energy, momentum, rotation.
Calculus-based electrostatics, circuits, magnetism, and electromagnetic induction.
Java programming, OOP, data structures, algorithms, and recursion.
Computational thinking, abstraction, data, algorithms, internet, and impact of computing.
A 10-question diagnostic identifies your weakest skills. The engine maps prerequisite dependencies — if you struggle with derivatives, it checks your limits foundation first.
Skills transfer across AP STEM subjects. Master stoichiometry in AP Chem and those quantitative reasoning skills carry into AP Bio and AP Environmental Science.
The engine tells you when you’ve mastered each skill. No wasted practice on concepts you already own — every question moves you forward.
Our adaptive engine has been validated across three independent datasets. The same prerequisite-aware sequencing that works for SAT Math powers every AP STEM subject.
Master derivatives in AP Calc AB and those skills carry into AP Physics C. Algebra skills from Precalc transfer to Statistics. Switch subjects anytime — your progress comes with you.
