I used Gleim to study for the CMA exam last summer. Putting in about 50-100 hours of study per part I was able to pass each of the four parts on the first try. In addition to passing, I earned the highest cumulative score for the four-part test for Summer 2010 and will be awarded the Johnson & Johnson Gold Medal by the IMA. I couldn’t have done it without the Gleim materials and strongly recommend them to anyone who wants to pass the exams.
