Hi Aradhana, first of all congrats for your result. Generally IIM gives weightages separately to the 10th, 12th score as well as UG scores and work experience. It gives credit points individually for each and every criteria and on the cumulative basis they roll out calls.

Anyway you can have a better idea of the IIM path using our pathfinder - https://bschool.careers360.com/pathfinder/cat
