To be honest, Your expectations are exceeding to what you have already delivered. Even going ahead with the anticipated results that you will achieve, the selection criteria is so different. Every part of your academics has been allotted a sectional marking scheme. Each IIMs have different weightage assigned to different academic milestone events. Presuming you don't have any prior work experience, you will not get a single marks in work experience part. Similarly, your 10th, 12th and graduation marks will be evaluated against a nominal scale with defined weightage. Apart from it, the CAT percentile has maximum weightage which will surely help you out in overcoming the patchy past. Even you can work alongside with your preparation for getting an extra edge in the work experience section. I hope I answered all your queries. You can write me back if you get some extra doubts.
