So I bought the OG 11
two years ago thinking I would start studying for the GMAT. It ended up just collecting dust and this time I am serious about studying. I recently purchased the MGMAT 4th edition set of 8 and I plan on starting to study soon.
I know that on the MGMAT website there are conversion tables for OG 11
with the 4th edition book. However, is it worth it to just buy the OG 12
? Will the money be better spent on buying the newest verbal and quant book? Please give me some advice!
