His O-chem videos were good, but he does not cover all O-chem 2 reactions that are in Kaplan BB and he also just kinda skims over carbs/proteins/lipid/etc.
Depending on how you look at it this can be good since you focus more on the things that are likely to show up. But just know that if you only study what's on his videos, there's chance you could be underprepared. Personally, Chad covered just about everything that was on my ochem section. However, I wouldn't use only his videos unless I were really short on time.
