Hello,

To have admission in diploma in business management you son is not eligible right now, because as per eligible criteria for diploma in business management candidate have to pass 10+2 or graduation with atleast 50% . So to tell diploma in business management admit your son to 11 and 12 th.

Or after 10th your son can choose diploma in business Administratiom of 3 year and then go for other graduation courses like BBA, B. Com  etc.

And further you can go for PG courses like mba.

All the best!!
