Hi Anirudddh,
As BB has pointed out, there are a number of 'issues' with how you worked through that section, so there's no practical way to define your current 'Verbal ability' or likely Verbal Scaled Score based on these results. Based on what you have described, I assume that you have NOT taken any FULL-LENGTH practice CATs yet - and you really should take one. That score will give us a good sense of your natural strengths and weaknesses and will help provide a basis for comparison as you continue to study. A FULL CAT takes about 3.5 hours to complete, so make sure that you've set aside enough time to take it in one sitting. Once you have those scores, you should report back here and we can come up with a study plan.
I'd like to know a bit more about your timeline and goals:
1) What is your goal score?
2) When are you planning to take the GMAT?
3) When are you planning to apply to Business School?
GMAT assassins aren't born, they're made,
