Oh I hear your pain!
Originally when I started (August 2004) I SUCKED
at all LR-Must be True, Assumptions, Weaken, Strengthen, the works. LR was the only section holding me back from breaking the 160's (yup, my LR was that bad. For example, my first diagnostic I had 10 correct on the first section and 11 correct on the second section) Even after I took the Powerscore course, it was still my weakest area (and even then..I was *barely* breaking the 160's.) Before the full length course, I had already read and reread the LRB and I had taken another weekend course to master LR..I had (in sum) spent a shitload of money and time on understanding LR...but since Oct 2005,it's changed. I don't really struggle with finding the right answers. The questions just click now. Things sort of just pop out. Although it was damn hard to believe I would get better at LR, it did happen! It just took me longer than others. I'm no where near getting these sections perfect but on my last test I scored 22 on my first LR section and 23 on my second LR section.
So you are not hopeless! Keep on practicing the blasted LR questions and remember to review your errors and correct answers at a comfortable pace. Take long necessary breaks when you need to. But don't give up
You have a shitload of time till June..
