GMAT Verbal score improvement help?

[scn]

Hi Erin

I am quite new here and need some help in verbal. I have dozens of GMAT books!!
OG,Kaplan, PR, ARCO, Cliffs, Barrons and Petersons. But due to little time, been
practising the Official Guide and a oocasional review of PR and Kaplan. I have found that my
weakest are the reading comprehension and the SC. I get about 30/33% wrong on these two sections,
any help suggestions to increase the scores on these two would be welcome.

On the PS/DS/critical reasoning I consistenly get about 3%,5% and 10% wrong respectively so my
priority is to improve the reading comprehension and SC section scores.

Thank you very much!
