OAT Organic Chem

Hey everyone!

I have a quick question with regards to the organic chemistry section.

Last semester in organic chemistry we took the ACS exam as our final- which some of you may have also taken as well.

My question is: how does the organic chemistry section on the OAT compare to the ACS? Or are they completely different?
I would just like to know so I know how much time to spend on reviewing ochem. Thanks in advance!
