Beat me to this :)

You beat me to the punch ;) I just found the set of Sal's videos, where he goes through every one of the PS and DS problems in the 11th edition OG.

Unfortunately, for me I am using the 12th edition OG, not sure if we can bribe Sal in some manner to go through the 12th edition :D

In a few cases, I think Sal just blasts through the question with brute math when there is a quicker way to tackle the question with a quick chart or grid.

Overall, these videos are great. Sal explains the questions very well, this guy is awesome! Thank you for posting the link.

Anytime Bynddrvn!
How are you finding OG12?
Have you seend OG11? Assume you have?
Is OG12 much different?

My approach is to just to annihilate all OG11 questions. Since I have that and not OG12. Once I have fully understood all those questions Ill move onto OG12 for more practise!

OG 12 is more challenging than the OG 11

Hi Tam,

Actually, I was able to see both versions. My OG 11 was misprinted so I returned it for an OG12 version. The math section is more challenging in the OG 12th edition.

The Manhattan GMAT website has a really good breakdown of all the changes:
