Yes the books are quite expensive. Sadly, I purchased the books at the full price at Barnes and Noble before noticing the discounts offered through this site.
Anyway, prior to using the MGMAT books, my CAT avg'd an embarrassing score of 360 (yea, really, really bad and this was after going through Kaplan's Math Foundations book). After using the bk 1, 2, and 5 MGMAT quant books I was on a 620-650 scale, but after 3 weeks of no studying (long story) I've been averaging 550-560. Which isn't great. But once I go through book 3 and 4, then I can accurately let you know where I stand in terms of the practice CAT's but for now;
After the 3 weeks away from the GMAT books (not my fault!)
It was way too late for me to change my test date, which I sat for today and ended up with a 550, Q40 V26.
Not great but, I know that if I had gone through the Word Translations book (which is my greatest Math weakness, it gives me headaches) and learned the VIC's, my Quant score would have been much higher, along with some much needed practice to refresh what I learned from the previous MGMAT books.
While with Verbal, the score can pretty much tell you that I didn't even study the Verbal questions except for the ones I went through while taking the CAT tests. Again, time was against me, and with my schedule off by 3 weeks, I was unable to cover the subjects I needed help with. Anyway, I plan to take the test in December, which should be enough time to spend getting accustomed to the Verbal questions and its nuances.
Oh yea, I noticed yesterday that on the MGMAT student center page, you can generate an assessment report based on the past practice tests (I wish I had known that earlier!) because it breaks down how well you are doing under each subject. Great tool to help you figure out and fix your weaknesses.
Right now, I'm just going to take a break for a month, then go over every crook and cranny of the MGMAT books, reset my MGMAT CATs, take all 6 tests with one week apart. Once I get my scores to an average of 700+ then I'll take the GMAT prep questions to see if my scores remain on the same range as MGMAT. Then I will re-take the test. (Hopefully, I will be done with this by December, I really don't want to deal with the GMAT next year)
