{ "item_title" : "SAT -Mathematics -", "item_author" : [" Timothy Chae "], "item_description" : "Dr. Timothy Chae is a former university professor and SAT math specialist with over 20 years of experience helping students dramatically improve their standardized test scores. Through decades of teaching, tutoring, and research, Dr. Chae uncovered a surprising truth: even straight A students often underperform on exams like the SAT, ACT, PSAT, GRE, and GMAT not because they lack knowledge, but because they have been trained to follow rigid procedures instead of developing flexible reasoning and visual thinking skills.In addition to preparing students for college admissions tests, Dr. Chae has coached AMC competition students and served as a statistical consultant for U.S. Department of Education funded research projects. His approach is not guesswork; it is grounded in real classroom experience, cognitive science, and data driven insights. This SAT Math book is designed to help students improve their scores by strengthening core skills and building efficient problem-solving strategies. It is carefully structured to guide students through essential concepts, targeted practice, and step-by-step explanations, allowing them to study in the most effective and time-efficient way possible. - Table of Contents - Chapter 1 Algebra1.
