Would like to get your feedback/opinion on whether there is a value-add in going over the supplementary OG - Verbal and Quant guides in addition to the Big Book?
Wondering if there is a heavy overlap and if it is worthwhile purchasing them in addition to the Big Book....Any responses/guidance will be of help! Thanks...
This depends of how well you need to do on the test. If you're going for the high 600's and above, this might not be enough.
But if you're looking for more material, it's better to use the extra OG's than questions from other books.
