RE: the O Chem II final:
I abused the index of the book and found that many of the questions were rephrased directly from the chapters. Like I found the specific sentence that was represented by the question. I think it is open book because many of the questions are so trivial that no matter how well you know O Chem, you would be unlikely to retain that particular detail. At first, I found most of the questions to be pretty easy if you actually had read the chapters / studied... but there were a handful that were just too esoteric. Then, I realized, they had given me 4 hours to do 100 questions, and that I'd be a fool if I didn't look up any of them where I was uncertain. So, question about protein folding (for instance)? Check the index... yes, discussed on these three pages. Flip, flip, flip... hey, look, there is the VERY question written as a statement, including the particular answer choice.
It felt a little cheap, really, but I'd already been admitted and this last class was just a formality. I didn't even need a high score... just to pass it. And I was following the rules of the exam to the letter. I don't even feel wrong about sharing this, because I haven't mentioned any specific exam content, just discussed the published terms of the test set up and my approach to working within that framework.
Over all, I'm not sure that I learned much, if anything, in the course that would have been important for MCAT that I didn't learn elsewhere, other than a handful of NMR interpretation factoids that are already gone from my head now. It was just the last hoop I had to jump through, after I was already conditionally admitted. My O Chem I instructor at community college covered most of the material for the first half of this course, and my biology / biochem coursework in the past covered most of the latter half, so in many ways it was just a review / survey course for me.
In the same circumstances, I'd absolutely take this course again, as the ability to knock out a 16 week course in just about a month of actual effort, at my own pace and from home, was an incredible benefit. But if I were coming to organic chemistry with no prior knowledge / experience / interest, and really needed to learn it from scratch, I'd stick with my local community college. There would be a hands on lab and interactive lecture, which can be helpful for mastering new concepts, and at 1/3 the cost. But then, I have a great local CC with moonlighting profs from the surrounding universities. YMMV.
