Joseph Hammerman

The author has a math degree from Johns Hopkins and more than 20 years experience tutoring ACT math and similar topics. He specializes in helping students get top scores of the math SAT and ACT and high grades in math honors classes. He has a documented history of helping students make huge improvements in test scores and grades. He wrote this because he needed advanced material for students already at a high score or had improved to a high score after working with him. The standard books were at about the same difficulty level as the real exam. He needed to assign large numbers of problems to get a few missed problems to go over. He needed a book that emphasized the advanced topics on the exam, so he created it.
