I took the Kaplan 9-class course from Nov to Dec - during this time, I was pretty much trying to complete the required assignments, and I wasn't too focused on correcting my errors. Huge mistake, of course. So although the course motivated me to get back into study mode, it didn't really help me as much as I expected.
That's when I discovered GMATClub and the techniques that some people here use, esp. the
error log. I purchased OG11 in Jan and that's all I used throughout Jan until my test day yesterday. I wasn't too diligent about planning out my studies, but I would try to do at least 10 questions a night from each of the 5 sections, if not, at least I would focus on a random area I was having trouble with in math and work on that. I feel like I could have really worked on improving my weak areas if I had more time though - instead, I really felt flustered and unsure of how to improve certain topics.
I also bought the
MGMAT Word Translations book and completed that which was a huge help, esp in rates and work problems. And I did a bunch of SC1000 problems a week before the test - it was my strongest area but I wanted to really nail it down.
Also, I think I did about 12 CATs from Dec until my test date - Kaplan at first (these REALLY discouraged me until I read about its inaccurate scoring on the forum), then PowerPrep,
MGMAT and GMATPrep.
Bottom line is that I definitely wished I was more focused - if I attempt this again, I will really maximize the usage of the
error log and plan out a study schedule next time!
