Sorry about the 27. I took my first and got a V42. Afterward I picked up
OG 11(havent touched it yet) Kaplan 800 and
MGMAT SC. The kaplan 800 is good for CR, helps you think a little more critically. I've been through about one third of the SC book and its great. I just did a GMAT prep and got V47, and I think after the SC book is finished will score even better. I would strongly suggest that one if you do not have it. And, as you have the quant down so well I would look at the SC like math. Memorize all the rules and apply them. I find as the SC questions get harder you definitely cannot rely on how they sound. I had a few where the correct answer was downright akward, I would not write nor speak that way, yet the test makes you choose the bizaare option. And the test is tricky. I got two of the exact same type of SC wrong. Damn them. Wont make that mistake again. So I think you could use a system of sorts. The other helpful tip that many have provided is to paraphrase the RC sections. I personally do not read them. I read the question and then look for the relevant section/answer. When I took the real GMAT I finished with 20 minutes left. Of course I ran out on Quant and only had 41!
I think with a little practice your verbal score will soar. You obviously have the brainpower based on your quant.
Best of luck.
