I passed parts 1 and 2 with only the Gleim book, but part 3 for me was a 1,000 times harder. After a few attempts using the entire Gleim part 3 package, I finally I broke down and bought the ExamMatrix software. I believe the combination is what finally helped me pass.
My struggle was that I had no background in accounting or finance whatsoever. Looking back now I probably could have done it with just the Gleim package (as many do), but after failng I lost confidence in them. I really liked ExamMatrix. Their questions are very different and will help you understand the material. I never gave up on Gleim though, as some days I would study it and then switch back over to ExamMatrix. Bottom line: Gleim and ExamMatrix are BOTH good if you really put your mind to it!! I do not think purchasing both systems are necessary or practical for most people.
Take it from me, you cannot just memorize answers for the math questions. You must understand the material to some degree as they are different on the test.
