About Math Zen: Exam Prep & Drill
SAT is October 3, PSAT is mid-October: drill the exact question types with 41 SAT-style problem sets.
Math Zen is a math practice and drill app built for real exam performance, not a calculator that does your homework for you.
Work through algorithmically generated problems that cover the topics and skills tested on real exams. The adaptive mastery-based progression system tracks your accuracy and adjusts difficulty automatically: struggle with a concept, and it comes back for review; master it, and you advance. Practice offline, anytime, with zero distractions.
EXAM PREP
Math Zen includes exam-style problem sets for major standardized tests:
- AP Calculus AB: 30 templates: particle motion, optimization, related rates, FTC, and accumulation functions.
- SAT Math: 41 templates with word problems, real-world contexts, and data interpretation.
- Gaokao Mathematics: 43 templates in formal Chinese math style.
- Suneung Math: 12 templates for the Math I and II common section.
- A-Level Maths: Pure and Statistics, covering calculus, trigonometry, vectors, probability and hypothesis testing. Mechanics is not covered.
- Also available: AP Calculus BC, Abitur, Kyōtsū Tesuto, Baccalauréat, Selectividad, EXANI-II, ENEM and GSAT exam paths.
Exam prep problems include multi-part questions, where each part builds on the one before it.
24 TOPICS, 570+ PROBLEM TEMPLATES
Six sections covering math from arithmetic through university-level content:
Algebra: Arithmetic, Algebra, Complex Numbers, Logarithms
Precalculus: Functions, Graph Analysis, Hyperbolic Functions, Sequences & Series
Calculus: Limits, Derivatives, Integrals, Differential Equations, Partial Derivatives, Parametric Equations, Polar Coordinates, Multiple Integrals, Laplace Transforms
Geometry & Trigonometry: Geometry, Trigonometry
Linear Algebra: Vectors, Matrices, Abstract Algebra
Discrete Math: Probability, Statistics
156 subtopics. 570+ algorithmically generated templates. Every session is different.
KEY FEATURES
Mastery-Based Progression: A five-level bucket system tracks your accuracy within each subtopic and advances you from easy to hard as you demonstrate understanding. Think of it as a private math tutor that always knows what to drill next.
Theory Built In: Every subtopic carries the rules its own problems need, with worked examples. Tap Show the rule the moment an answer comes out wrong, or open it from the header mid-problem.
Mistake Journal: Every wrong answer is captured automatically. Come back later and retry that exact problem type with fresh numbers, until the concept clicks. Resolve them all for a small celebration.
Visual Problems: Interactive graphs, geometric diagrams, and animated transformations.
Offline First: The whole app works without internet. Practice on a plane or subway; progress syncs when you reconnect.
No Ads, Ever: Clean, focused, distraction-free. No ads, no coins, no lives.
11 Languages: English, Russian, Chinese (Simplified and Traditional), Jap
