GST on Distance education courses

Hello,

We are an institute that offer higher education courses like BA, BCom, BBA (graduation) & MBA, MSC, MA (Post graduation courses). These courses are from UGC approved universities. 

When a student takes admission through us we have 2 components 

1. University Fee

2 Our Fee (learning center fee)

University does not collect any GST from us for the Fee paid to us as they are exempted from GST (I think under HSN code 999241) 

Need guidance how we should create the bill & generate invoice for the student so that we pay GST on our fee & not on the university fee. 

It will be great if we can discuss this with an expert & get paid advise also

Thanks
