Hey,

To be very honest I think your academic scores are little low, so it is advisable to score as high as possible in CAT in order to increase your chances of selection into top B schools. I think a score above 95 percentile will help you to get calls from good B schools.Still will suggest you to aim as high as possible. For more clear idea you can go to the website of top B Schools and can look for their selection criteria.

All the very best .

Thank you
