So, everyone has a different MCAT, obviously. I had taken physiology, had taken a prep course, and had studied my butt off for all sections. I wasn't worried about the Bio section because I *love* organic chem, and my understanding of bio was really good- even though I'm a post-bac student, I've had a LOT of anatomy/phys, bio courses throughout my life.
My bio section had a TON of biochem-based passages. Probably 7 out of 11. Although I could glean a lot of the info from the passages to answer questions, after I took biochem this past summer, I realized how incredibly helpful the class would have been on the MCAT. Yes, I scored in the double-digits on bio anyway, but not as high as I feel I could have.
So, that being said, I think the more tools and understanding you have coming into the MCAT, the more prepared and confident you will feel.
The most important thing about the MCAT is a) don't second guess yourself and b) don't panic.
And yes, EK is great for bio prep. Make sure you have some carbohydrate chemistry behind you at least.
