I'd like to clarify something. There is the same amount of ochem II on it as there is the DAT (which requires OchemII). HOWEVER, scoring is different. There's 30 questions, just like gen chem and i'm sure you have seen that there is a 3-4 question cushion difference between the two. I don't have the table in front of me but lets say that 18/30 scores you a 300 on gen chem. On ochem, 18/30 would score you a 330. Again, I'm making up these scores because I don't have the table in front of me, but you get the point. That's why I say that it is VERY easy to up your score on ochem by taking ochem II.
