RC help needed!

Hello everyone,

Here's my situation:

My first attempt on GMAT was around 6 months ago after preparing 2 months using Manhattan set of 9 books, OG, CR Bible, MGMAT & GMATPrep tests and scored 640(Q49, V29) but I want to write it again next month to raise my verbal to 40 so that I can land my target score of 720.

However silly it may sound but when I took GMAT first time, I had to skip 2nd and 3rd RC passage completely to get my verbal section done on time. I did this on purpose because even if I could manage to read the passages, I was not able to get any RC answers correct (may be 1 out of 4)! Of course, my reading speed is bad and so are my comprehension skills (I started reading novels only recently and am a non-native english speaker).

I wrote a sample GMAT last week after revising the materials and still got almost all RC answers wrong! I have read a lot on this portal and a few others regarding the RC techniques and strategies but due to the speed issue, I am not able to apply any while writing a test. I can't let this spoil my overall score.

So, please suggest me some proven, dedicated coaching or guidelines for practising RC. Any suggestions or feedback would be highly appreciated.

Thanks a lot!
