NEED ADVICE PLEASE

Hi house, my brother has just gotten admission into the dept of Banking&finance unical, but it is a consultancy programme and the issue is that they will not go for youth service but will be given nysc exclusion certificate. My problem is that the guy is just 19yrs old and will finish b/f 25yrs, and i don't even know the ground his execlusion is going to be based on.

I need ur advice cos the guy says i won't wait to write jamb again as he has written up to 4 times without making it. Do employers accept the so called execlusion certificate for young graduates below 30yrs.
thank for ur advice.
1 luv
