# GMAT Official Guide

I’ve classified all of the Quant Problems in the 2017 Official Guide for GMAT Review by content area. There’s a lot of overlap (e.g. triangles inscribed in circles), but I think that, fundamentally, it works. As you work though the OG the first time (yes, there will be more than one time) you should follow this classification.
