Once I am done with all math exercises from OG11, would you recommend to buy the OG10 and go thru it? What is the real difference btwn OG11 and OG10? (except for the fact that OG11 has the latest retired questions from gmat).
cheers!

If you are done with all the math questions from OG11, buy Math Quant OG book for more practice.

If you are referring to the OG11 review (green/purple book) I already bought this one too. I was wondering about the OG10. Are you familiar with it?
