Thanks for the responses. I Meant to say that the amount of info given won't be required, just an overview would be okay. but I have time so I'll stop being lazy and read it again carefully or I'll try and get an hang of ek orgo book and read it from there, I did read the BR topic earlier last month.
It is actually not that much. However, I will say this, the AAMC topics list is pretty vague. If you're shooting for a high score you NEED all the practice you can get and you need to see material presented in different ways. Not only does this increase general knowledge, but it also increases critical thinking skills and you can apply things from old passages to new ones. If an arrow pushing mechanism has been established in the literature for a reaction and the reaction is on the AAMC topics list, then I would know the mechanism. Likewise, if there is a lab technique listed, I would know EVERYTHING about that technique.
The only techniques in the AAMC topics list I see is:
-TLC
-Gas liquid
-Paper chromatography
then there is distillation and extraction. and that's about all, but then you can kinda mix in IR, NMR, mass spec, and boiling point into that. maybe even HPLC, not explicitly on there, but its similar to the other purification techniques so why couldn't it be on there? all in all, there is about less than half a page about lab purification techniques, but i wouldn't leave anything to chance.
its best to be familiar with something, or even have seen it once instead of seeing it on the test the first day and just having the WTF look.
all in all, the curve for a high score is very steep. if you want to guarantee yourself higher than a 33+ then you NEED to know pretty much everything (no one should be aiming for a 30+ "cuz that's all i need w/ my gpa" or w/e, you need to aim for a 45). you might not need to memorize it all, but be familiar with the concepts. at the end of the day its up to you, but my advice would be to not skimp on anything.
