BR orgo lab techniques overdone much?

Do I need to even be "familiar" with all of that? I studied all/most of that in my science classes but assume I don't remember it. I see most of the practice passages laying out all the info but just wanted to ask the more knowledgeable!
 
On an exam where many passages are based on an experiment, lab techniques (not just in o chem but all sciences) are essential. Look at the AAMC topic list and you'll see how much they expect.
 
I thought it was one of if not the best chapters but I've also taken a very rigorous Orgo lab course so almost everything was familiar.It's probably one of the less important topics on BS so if you're pressed the time maybe study something more important.
 
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.
 
i swear i would have left it if it wasn't for SDN and all the supportive people out there in the same boat as me!
But EK seems good for me in that area as i feel like i have the basics of all these techniques so EK then BR for passages...life will be so awesome if I could get 35+ on the real deal
 
Meh, i didnt feel EK did a good enough job covering all the techniques as BR did. When I did my passage practices with EK I basically relied on my own lab experiences, not what EK taught me to answer the questions. I did pretty well so I just went over what I got wrong and reviewed those sections while glancing at everything else.
 
Better safe than sorry, you paid good money for your TBR books. You will kick yourself if you forget some basic laboratory concepts on the real deal. The chapter on orgo techniques is much shorter than all their other chapters anyways.

And for topics you should be "familiar" with, refer to the AAMC topic list.
