About this app

Killer Math is a learning app that compiles and displays only "killer" and "near-killer" math questions from mock exams and the CSAT administered to 1st, 2nd, and 3rd-year high school students since 2023. Instead of skimming the entire curriculum, you can study by selecting only the high-difficulty questions that differentiate students' abilities, featuring clear formulas, diagrams, and step-by-step explanations.

No registration or login is required. You encounter the problems immediately upon opening the app, and content downloaded once can be accessed even offline.
