I passed my class 12th one year ago with 75% with 80% in class 10th from up board. Should I stop thinking about iima now?
Although you have an average academic record in 10/12, assuming you are from General Category I still believe you can get a call from either of IIM A B C , with a strong score in CAT (99.7+) , an excellent academic record in Graduation, followed by a great GD/PI and WAT.
