I was fortunate enough to purchase the MGMAT books, OG11 and the Verbal and Quant books for $20. However, the OG 11 is outdated. GMAT Club did such an amazing job providing us with a guide to the OG. I wanted to create one for the 11th edition. I leveraged the 12th edition one to do so. I began this process 2 weeks ago. The following day, I attended a school visit for CBS. They also had a GMAT presentation by the MGMAT folks. Long story short, at the end of the presentation they raffled off a course and I was the lucky winner. Couldn't help but think that this was some good karma my way for preparing a guide for the OG 11th Edition.

I have now completed this comparison and I hope you find it useful. If I have missed something please let me know so I can correct it.

The intro page was not updated... looks like the analysis tab didnt pick up the changes as well... however the error log is correct as it stands and it is for the 11th edition ... will work on the other two tabs tomorrow

Updated version... analysis tab and into has been updated to reflect 11th edition.

Unfortunately I do not have the OG12 to 10 comparison
