Kaplan Math Vs OG Math supplements

[gennatay]

I need a lot of help with the quantitative section and I want to buy get a supplement. I have the OG 11th and Kaplan 2009. Which supplement would someone recommend? Are the questions in the OG supplement the same questions that are in the OG?

The Kaplan book breaks down the different quant sections and provides strategies and tips while the OG Q book only has problems without any strategy or real breakdown of questions (although it provides a very basic math review section, but if you have the OG11 book, it contains the same math review). The OG Q and OG11 do not have overlaps. If you want to really cover the basics and fundamentals, go with the Kaplan book.
