Hi gmatwithpooja,
From your post, I assume that you're not performing well when you deal with RC prompts/questions during a CAT.
To improve in RC, you actually need to improve in a few areas, including HOW you read (become an "active" reader), your note-taking, your ability to find the common 'clues' that many RC questions are based on (and move past the filler/details in the prompts), your understanding of the common question types and the typical wrong answers that often appear, etc.
You also have to consider the format with which you study. The GMAT is administered on a computer, so practicing out of a book or off of audio-files is NOT a realistic way to build those RC skills in the long run.
How long have you been studying?
What resources have you been using?
What is your goal score?
GMAT assassins aren't born, they're made,
