Hi Olivia700,
Before you focus this energy on one subject, I'd like to know how you're performing overall. There might be other issues that are MORE important to your overall score than becoming stronger at dealing with RC.
1) What is your goal score?
2) How long have you been studying?
3) What materials have you been using?
4) How have you been scoring on your practice CATs (including the Quant and Verbal Scaled Scores)?
5) Do you have a pacing problem in the Verbal section? Do you have to guess on a bunch of questions just to finish at the end (and how many?)?
6) When are you planning to take the GMAT?
Even though RC can be 'tough', the design of RC passages and the accompanying questions (and even the answers) fall into predictable patterns, so you CAN train, improve and score at a higher level.
GMAT assassins aren't born, they're made,
Rich
