Dear Saurabh, You haven't mentioned your Category. Neverthless, to be honest, your 10th and 12th marks may not favour you. But your Graduation aggregate is fantastic. When the IIMs shortlist candidates for WAT, they consider factors like your Academic profile, your CAT score, diversity factor, etc. Few IIMs also consider Work experience. Now 4.8 CGPA and 69% in 12th, you will not gain much points on the rating scale. With 90% in Graduation, you might get 8-9 points. But with your 10th and 12th marks, you may get 2-4 points on the rating scale. And considering these 3 scores, your points might be between 12-14. Which means when IIMs shortlist Candidates for the next round based on your Category and all these factors, you might lag a little. But let's say you scored 95 percentile in CAT, you may have it to your advantage but no offense and hope  none is taken, you might fall behind in being selected. But there is an advantage here that you are studying CA. Professional courses like CA, MBBS, etc get additional points because of the diversity factor. If you want to get into an IIM, you should finish CA Final and use it to your advantage to secure a seat in the shortlist. Meanwhile as you have already completed your Graduation, if you can join a job, your work experience will show up and it will add few more points to your profile. Then access to study in  any of the IIMs becomes much easier. Inspite of all this if you get a call from an of the IIMs with this current profile, nothing better than that.
