Hi,

Would be great, if someone could point out the difference in the content between OG 12 & OG 11. I have OG 11 and would prefer to purchase OG 12 only if the content is significantly different/enriched.

Thanks,
Pankaj

Hi Pankaj,

A while back, MGMAT prepared this comparison: https://www.manhattangmat.com/official-guide-12.cfm

The important info: Only 1/3 of the questions are new. Out of 907 problems, 607 are repeats.

I hope that helps,
Brent

I primarily only used OG11 for my studying. I borrowed OG12 for a day but didn't find the questions sufficiently different that I needed to go out and buy it. As Brent stated, there are new questions but unless you don't care about spending money on a very similar book, I wouldn't say it's necessary to go out and get it.

Thanks Brent & Linawangfang for your comments!!

One more thing, is it possible to get the error log for OG11? The one which is currently on the BTG website is for OG12.

Thanks!! :)
