I have the OG 12th Edition; I want to know if the 11th Edition helps any further?

I've read a few posts where people ask about the opposite, i.e. having 11 but wondering 12 is necessary - for me, it's the other way round.

I know there's an overlap of about 60-70 percent of the questions, but are the 300 questions that have been replaced worth going through the older OG as well?

I actually think OG 10 is a must for verbal basics ... over 260 SC questions ... i don't think u need the other OGs for quant atleast I did not need them!

IMO you don't need to buy OG 11.Even tough there are many problems which are in OG12,it ll be of same pattern covered in OG12.Instead of having OG11,go through OG 12 problems again and you are able to understand the problem quickly,solving it accurately.

The OG 11 only has 300 different problems. If you do end up getting this you can go to the Manhattan GMAT site and find the document that shows you where the different problems are. However, I think that you would be better off just buying the verbal and quant OG books if you need extra practice.
If my post helped you- let me know by pushing the thanks button ;)
