jhyamma and lostofdeal,
                                    Thanks guys. My GA is semester based. there is no hours specified for GA. GA just  included the tution reimbursement for 6 credits that i am taking this semester which in my last semester.

I am working with same professor for GA and  for the project. the project is also related with the university( i mean i got the payment from financial office of university during summer and its hourly based. I didn't have assistantship during summer thats why i worked full time. If i continue the project, they will pay same way. i got 15 hrs for project.

so here is the question, No specified hours for GA and i am not getting any cheque for GA i.e. it is just tuition reimbursement and i already got it. so what is next? please, your suggestions.

My professor is my buddy and he definitely helps me but i have to tell him all the procedures.
