I used a combination of Princeton Review (Cracking the GMAT, Cracking Quant, Cracking Verbal) but stopped after reading through those once as I found the questions were too easy and not reflective of the actual test. I did find some of their methods helpful. I also used the Kaplan GMAT 800 once I felt comfortable trying to tackle harder material; I used
the Official Guide for most of my nightly practice questions. I used CATs from all of these providers as well as 6 from Veritas Prep. I feel part of the reason I did so poorly I had trouble creating a rigid study guide and schedule; I also only made an
error log for my CATs but did that later in my studies. I'll be sure to do both from the onset of my second attempt.
I would say that for half I did the full CAT and the other half I only did the Quant and Verbal sections. I took them at my office every Saturday afternoon since I was most often the only one there and would try and mimic the testing conditions as close as possible (i.e. no music, one screen, etc.) I've taken several licensing exams at Pearson testing centers so I am fairly familiar with the environment and don't think that was an issue. However, I took the actual exam in the morning and my practice tests in the afternoon which I think could have affected me (I am definitely not a morning person). There were a few times my browser would crash during a CAT and I'd have to pause the exam but overall I tried use the CATs to get used to the pace of the test. I think nerves, timing on Quant, and overlooking the IR section are where I really struggled.
I don't have all the scores for my practice CATs (again, I know I should have done an
error log) but I've listed the ones I recorded below in chronological order:
1.) Princeton Review: Q39/V33/T590
2.) Princeton Review: Q33/V33/T580
3.) Veritas: Q37/V34/T590
4.) Veritas: Q40/V40/T650
5.) Veritas: Q40/V42/T680
6.) Veritas: V44/V42/T690
7.) Manhattan: Q38/V38/T640
8.) GMAC: Q38/V40/T650
When I switched to Veritas I noticed the Quant material was substantially harder than PR so I really honed in on my weaknesses and tried to understand why I was getting the question wrong/making careless mistakes rather than how to answer and saw an improvement. I think some of it honestly may have been blind luck as I failed to address timing issues and focused more on content; I also found a lot of careless errors were made due to overlooking exactly what the questions were asking for (i.e. solve for x, mistake for value of y). I really don't know how or why my score dropped of so substantially in the actual exam but I'm confident I can score in the high 600's. Ideally, I'd like to score at least at 700 but know it may take a few tries. The schools I'm interested in are Darden (UVA), Kenan-Flagler (UNC), McCombs (Texas), Wake Forest, Jones (Rice), Freeman (Tulane), and Goizueta (Emory). Many of these are a reach but I'm especially interested in Rice and Tulane.
Thanks again for any advice and help.
