Each book in the series contains 1,000+ carefully organized problems, built to take students from core concepts all the way through advanced applications and AP/IB-level work.
This series was built as a learning path, not a random collection of practice questions. Each volume covers one grade level, with problems organized by type and difficulty so students build understanding progressively rather than jumping around.
Every volume contains over a thousand rigorously selected questions, organized from foundational to advanced. Students get consistent, high-volume practice without repetition for its own sake.
The series is designed with AP and IB curriculum standards in mind. Students using these books alongside our courses are covering the same concepts they will face on those exams.
Problems progress from concept review through to cross-chapter integration and complex application. Students are not just drilling. They are learning how to think through harder problems.
Sophia Li is a North American AP and IB math educator with decades of experience in international curriculum teaching and university admissions guidance. The series reflects what she has seen students consistently need, and consistently struggle with, across years of working with students from Grade 5 through university entrance.
