What have you used for practice?

I think the Official Guide in conjunction with the OG Companion (from gmatfix.com) gives the best DS practice.

When I studied, I broke DS and PS into specific topics (such as Number Properties, Linear Equations, Absolute Values, Rates, Percents, Triangles...) I used the OG Companion's reference section to figure out exactly which questions fit in each category.

Each day, I would study 2 or 3 specific categories by practicing out of the OG and then reviewing the thorough solutions and lessons in the OG Companion.

You can see a review of this book in another posting at www.tinyurl.com/OGC-review

If you've been through the OG11, consider getting the Quantitative Review Supplementary Guide or the OG12
