I need advice of experienced test takers (i.e., those who have already prepared and taken the GMAT) on the best source of identifying weak areas in both quant and verbal.
The question is not on using an
error log but on books/courses that are most representative of the actual GMAT requirements and that are able to test your ability in these areas (at least to some extent).
In order to save OGs for the latter stages of my preparation, I plan to start with Kaplan Premier 2009. Do you think that this source is good enough to identify blind spots and weak areas in both verbal and quant?
If not, what is in your opinion the best way to identify blind spots and weak areas (what courses/books are the best for that)?
