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 However, the OG 11 is outdated.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.

Thank you for creating it.
One comment I can see is the "Intro" sheet - it still has OG 12 information.

Also a question - on the Error-Log Tab - I see there are 788 questions and on the Analysis Tab, I see 807 - is that because the 807 refers to OG 12 or ?

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

I was looking for something like this!

Thanks!

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

This is quite useful .. do u have this for OG10 / OG12 as well?

Unfortunately I do not have the OG12 to 10 comparison
