I read this about national open university .
PT: So now what happens to the people who graduated previously without going for NYSC or law school?

Adamu: I am a teacher. We have the list of NOUN students who have graduated but could not go for NYSC. They are given exemption certificates and we are taking care of that. The only problem are those who are not up to 30 years who couldn’t collect exemption letters. Maybe by the time the process of amending the Act is over they will be up to 30 and then we give them exemption letters.
Does this mean those who are below 30yrs are wasting their time in Open University
