As someone who has worked for a college the last couple years, I can say that I wouldn't have it any other way. Sure the pay isn't great but the flexibility cannot be beat and the learning that takes place is immeasurable. The experience gained gives a huge leg up on any competition for a better position.

I'm sure you will do great. Peer advising is wonderful because with each person you talk to, you learn something you may not have already known. Besides, when you talk to an adviser, you get their professional input. However, a peer adviser can offer more practical information that students need to hear.
