Hii,

The final Admission to the IIM's depends on the CAT Score, Academic Marks, Written Ability Test(WAT), Group Discussion and Personal Interview. Your Academic  Marks are quite Impressive and will help you in the admission process. You need to get a Decent Percentile of 95 and More to Crack IIM's. After securing a good percentile if you can perform well in the GD and PI then you will get admission in IIM's for sure.
