Applying for a bursary

Q: I am a post graduate student. My question is regarding a scholarship which I applied for and wanted to ask if it is ok for me to take.

I am presently studying in a different state and this scholarship is from the central govt. but I needed a proof of residence of this state for the application. So I got in contact with an agent and he managed to get my application approved for which he is taking a part of the scholarship money.

Anyway, generally I never applied for scholarships in my schooling or college or bachelors but because I have a few unplanned heavy expenses related to my education course, I applied for it thinking it would help. But I am in a dilemma whether to use it or dispose it or just use it for this particular purpose and dispose the remaining or use it for my other personal expenses and if not, then how do I dispose it?
