GMAT Strategy

I need to improve my verbal score by at least 5 points. I am getting 30 on avg, and I want 35.

I am slow in the verbal and after 20th question I see that I do more mistakes because of the time pressure. I see that I spend much time in the RC, and do not get all the question right.

My question is: Is it okay to just blindly guess all the four questions, if I find just by reading few lines of RC that its hard? This can save me 12 minutes, and I can use this time to correctly answer other question. I know I'll be penalized if all the four question goes wrong.But how hard will be the penalty?

Will it matter a lot even if I do this at the 20th question ?
I have the test in 15 days and want to finalize my strategy.

Please help.

RCs u have to get adjusted to them. U have to take around 3 min for a short one and 4 min for a long one to read and make some notes n 1 min for each question.
