Well.. there are two general advices for improving your reading skills.when you are studying for the lsat, working and/or going to school it is a little to late to suggest reading a lot to someone. for the most part, any free time outside of work and school is going to be spent studying lsat material not reading the economist in hopes of raising your reading comp score. with the test two months away, i would do a myriad of actual reading comp passages and really study what it is you are missing in the passage when you get a question wrong. sure it is easier said than done, but with such a short time left until test day i think that is our best bet.
1)Read alot. read everything and anything, read like you will never read tomorrow. read when you are in a bus, read when you brush your teeth (okay maybe thats's a bit too much) but you see my point. the purpose for this is to increase the speed of your reading. your eyes are trained to read a lot of materials so they move faster.
2)read the stuff that bores you. and fake the interest when you read them. Your brain processes information faster when you read something that excites you, even when you fake them (easier said than done though, it was very hard for me to fake interest when I read complex geological settings of somewhere in u.s.).
anyway, it is a natural tendency for all of us to skim the material even w/o really understanding it if it's something boring to us. so yeah, fake the interest.
I read these advices from this word file someone created back in 2003. She scored 176 in LSAT and had created a general advisory word file (33 pages) that was really helpful.
with two months remaining, I actually did read alot of outside materials. I subscribed to International Herald Tribune and read the opinion section, disecting the arguments, every day. I also got back issues of scientific american from my friend's bathroom and read an article every time I had a chance (maybe every other day)
My RC score improved throughout my practice exams. and no,I cannot say that it was necesarrily the outside reading that contributed to the incline, but it might have been. like all we know, these are all subjective views/advices. so take what you need and leave what you don't need.
