Your CAT weightage is considered only upto 40-60% based on the IIM that you are applying for. Each IIM has its own selection criteria. Even the baby IIMs require CAT percentile 40-60% and the rest is considered from your 10th and 12th, Graduation marks and diversity factor. Most IIMs will need atleast 18 months of work experience. Considering all these factors, a call from any IIM will be difficult even with 95 percentile. Because only 60% of your CAT score will be considered for shortlisting your profile for next rounds. In that case, you will losr out on your 10th marks and work experience.
