I think it depends on how well you think you've learned and internalized the material from Orgo 1. The MCAT generally focuses more heavily on concepts from the first semester of orgo, and if you understand these very well, that will be an advantage. The key concepts from orgo 2 are more memorization heavy, although for most of them a good understanding of the behavior of carbocations, nucleophiles and electrophiles will help you comprehend what is going on, rather than just memorizing. I agree with previous posters that Orgo 2 tends to get a bit more unmanageable than Orgo 1, but keep in mind that the MCAT does not require the level of memorization you would need for your orgo final -- it's much more oriented toward facility with the concepts, rather than rote memorization. Anyway, think about how comfortable you feel with orgo, and how much time you can devote to the MCAT. I do think it's possible. Good luck! 🙂
