Hey Aditya! 

I would say, it's normal to score in this range during the initial or middle of the preparation. And, you are doing the best step by analyzing your shortcomings and trying to overcome them. Just try to go back to the particular section in VA/RC you are making mistakes, understand where you are misinterpreting and practice that section multiple times. Then, go back to the exam section of the same section and try to give the 15 or 30 min mock test of the similar pattern. Secondly, don't stress yourself much, especially on the exam day. The question paper will be much easier than your mocks, just proper decision-making skills and calmness is required.
