Is it possible to pay the principal on my student loans while I am still in school, without paying the interest first?

I have student loans through FedLoan, and am currently deferring while in school. I am wondering if I can pay down my principal before paying down the interest. Obviously this would be beneficial, because my interest won't capitalize for a while. Is it possible, or do I need to pay the interest first?
