Worth Reading chapter 11-13 of MGMAT Sentence Completion?

can you link me to the GMAT notes you are taking about...there are way too many lol

I would focus on the weak spots. Where can you improve the most? Sometimes those chapters may be helpful and sometimes you may need to go back to chapters 2, 3, 4 and go over them again. I would focus on your weaknesses.... and when you ask this question, you should probably mention what you trade off is.... if you expect a good answer. e.g. what else you have to do in those 2 weeks you have left?

thanks bb, everything else seems pretty solid, my quant average is about ~Q48-49, my verbal average is about V30,
my RC and CR are pretty solid - i get about 80% of medium questions correct and 50% of hard questions correct,

However my SC averages at about 6-7 questions correct out of ~14.
I feel like SC is such an easy thing to improve. However, I am on online forums and Facebook all day, and I feel like I have picked up a lot of bad habits, especially because of lazy speech habits from Instant Messaging Programs.

I've read the MGMAT SC a couple of times. I think its easy to identify the errors at the end of each chapter because I know what I'm looking for; but when I am given a random SC problem, I kind of freeze because I'm not sure what to look for.
