Study OG Solutions or Do More Questions?

[modesto2]

I scored 670 on my first GMAT attempt and am preparing to take the test again in two weeks. I completed OG12 and Kaplan Premier and have identified CR and DS as my weakest areas.

In the next two weeks, should I focus on...

(1) studying the OG questions and solutions

or

(2) try to do more questions from other sources?

From what I've gathered, it seems that I should be focused on the OG solutions. For verbal, that's studying the right and wrong answers, and for math, that's studying the solutions.

What are your experiences with making a log of your errors, etc... I think I should focus more on recording my mistakes and ensuring that I don't repeat them.

Thoughts? Thanks for your help.

It might help if you were able to identify with more specificity what types of CR weakness you have i.e. is it strengthen, weaken, or inference questions that get you. Same with DS: is it number properties, inequalities, percents, that defeat you. If you can ID more specifically what topic of quant and verbal rather than generally what type of question bothers you you can really focus on that. If inequalites DS are a problem you can really spend a day on that and clean it up. I think that is a more effeciant use of your time than just generally doing all types of DS.

Hope this helps.
