It sure does. However, in my opinion it also very relative. If you took Orgo classes in school recently and are familiar with material, then EK is great. However, Kaplan can be beneficial if you are not familiar ( also be aware that Kaplan has some extra info that you really don't need for MCAT). Hope this helps. Also doing EK and Kaplan simultaneously is not a bad idea.
I think EK Organic is enough, but then again my studying for organic was minimal to say the least since I had finished ochem 2 two months before taking my exam. My review was basically passage practice. That being said no matter what books you use for organic, pay attention to:
- SN1/SN2, E1/E2 and all their nuances.
- Naming, drawing from the names and naming from the drawn compounds.
- Common lab techniques such as distillation (simple and fractional), chromatagraphy (column, gas, liquid), recrystallization, etc.
- Common identifying techniques such as UV/Vis spec, IR spec, NMR, and mass spec.
- Proteins, carbohydrates, and lipids. This is where biochem helps a lot, I think this is also where EK doesnt give enough details if you're weak on macromolecules.
-Common syntheses reagents and reactants, the ones that you dont need to know the mechanism for, but still have to know what the product/starting materials are and a general idea of how they work. For example, you should instantly know what reagents such as H2/Ni, LAH, Jones, or KMNO4/HCl do to different starting materials and how things can change depending on the starting material.
Organic chemistry is a lot of understanding why and how, and not a lot of pure memorization at all. If you were ever good at it, I think learning it again is like relearning how to ride a bike. Its simple, and can be as little as looking over mechanisms again firing up connections in your brain that make you remember 'oh yeah, that works because of this, this, this, and this' even though you only have a few words written down in your old notes.
