Hi,

Your son is definitely eligible for MBA. Even, if the top IIMs doesn't consider, as they even consider the past academic marks. But, few new IIMs as well as colleges like IIFT won't consider his engineering percentage or past academic marks. Tell him to give his best shot and ace it.

Yes, he is definitely eligible for CAT and other management entrance exams. Kindly advise him to start his preparations if has'nt yet. Hope this helps.

All the best!
