After that, one RC passages came and I checked the time at 20th questions and the difference between time taken and target cumulative time were 7-8 min.
And it's the case that you specifically lost all of that time on the RC passage and questions? Or were some of the others too long as well? For the RC, did you spend too much time on the first question (which includes your initial read-through)? The later questions? All of the above?
Note: for RC, expect the read-through + first question to be anywhere from 3 to 5 minutes, depending on length of passage and whether the question is general or specific.
For later questions, expect to average around 1m for general questions and 1.5 to 2m for specific questions.
Agreed that you don't want to skip one entire RC passage. But if RC is your weakest area scoring-wise, then you could skip one RC question within the passage - then you can spend a little more time on the other questions and yet still not be behind on the whole passage.
You can make more than 6-7 mistakes on verbal. That's your weaker area, so your quant is what's going to be pulling your score up. On verbal, you're likely going to be in the 60% correct range, so 40% wrong = 15-16 questions!! Yay! :) You just want to make sure that you're getting the hard ones wrong - in other words, you're choosing which ones to skip and get wrong, rather than being forced to guess at the end and get a bunch wrong in a row, some of which you could've gotten right with better timing.
Also, buy a can of tennis balls. Keep them on your desk or with you when you're studying. When a problem just isn't happening, pick a ball up, say "Nice shot!" and then get ready for the next point. (That is, move on.)
Finally, here are some RC resources:
