Once I am done with OG11, does it make sense to buy OG10 (used maybe)? Is there any major difference btwn them?

OG11 and/or OG10?!?

I'd go with the OG V and Q books and the Kaplan 800 books first before resorting to the OG10. There is definitely overlap between the OG10, PowerPrep, GMATPrep, OG11 and the paper tests. Studying with new material is better in my opinion.

OG10 is too old to be useful in my opinion. As mayo said, get the current V and Q official workbooks instead.
