ACT - Mathematics -: 2026 New Edition

By Dr. Timothy Chae

Most ACT math books teach shortcuts. This one teaches students how to think.

Dr. Timothy Chae is a former university professor and Math and Statistics specialist who reveals a proven method for raising standardized test scores without endless memorization or gimmicks.

After decades of teaching and research, Dr. Chae uncovered the real reason even straight A students underperform on exams like the ACT, SAT, PSAT, GRE, and GMAT. The problem is not intelligence. It is how math is learned and how test thinking is trained.

Dr. Chae has coached AMC competition students and served as a statistical consultant for U.S. Department of Education funded research projects. His ACT Math series is built on solid research, real classroom results, and over 20 years of university level teaching experience.

This book does not rely on tricks that stop working under pressure. It builds the exact skills the ACT actually tests:

Critical reasoning and logical thinking
Strong foundations in algebra and geometry
Data analysis and mathematical modeling
Speed, accuracy, and confidence under time pressure

Parents and students choose this series because it produces real, lasting improvement, not short term score bumps.

Inside this book, you will find:

High impact ACT question types that appear again and again
Step by step methods that eliminate careless mistakes
A structured practice system that builds mastery fast
Clear thinking frameworks that transfer beyond the ACT

If you are serious about raising your ACT Math score and building real math power that lasts beyond test day, this book was written for you.
