How can I get into XLRI with 8.0 GPA in 10th and 76% in 12th (MPC) and 6.5 in engineering? Will these marks affect my admission into XLRI or IIM even if I score well in XAT and CAT?

This depends on the score in XAT and CAT. If you are aiming for IIM Ahmedabad or IIM Bangalore or IIM Calcutta, then a CAT score of close to or more than 99.8 percentile is needed for a general category student.

You may get a call from other new IIMs such as IIM Kozhikode, IIM Indore, IIM Lucknow, and IIM Shillong. As far as 2nd and 3rd generation IIMs are concerned, then a score of more than 96 percentile is enough to secure the interview call.

For XLRI Jamshedpur a XAT score of more than 98 percentile is enough to get a call for the interview process. The institute gives somewhere in the range of 10% - 15% weightage to 10th, 12th, and graduation marks.

Next is your performance in the WAT and PI which will determine your eventual admission.
