Official Guide (10 or 11) vs. Real GMAT

Hi everyone,

I have some questions for those who have taken the gmat and score very well (above 90th percentile) and used the Official Guide (OG) as the study tool:

1. When you practiced using the OG, did all of you always answered 90+% of the questions in each section correctly? I understand that most of the questions in OG are in the Easy-medium difficulty level, and that we should put more attention to the harder level questions. However, I was just wondering weather the performance in OG can be used as a predictor of the performance in the real gmat.

2. How many of you had problems with some of the difficult questions (especially in the PS and DS Math sections), and still did very well in the real gmat?

3. For those of you who had consistently answered 90+% of the questions in each section correctly, how many of you didn't get above 90th percentile in the real "gmat test".


I'd like to thank all of you in advance for answering these questions. I just want to see how the OG really helps with the score.
