I've been awarded 4 year scholarships from the army and navy, both for villanova university. Navy is my preferred choice, but i accepted the army one because i got it a while before the navy one. I would go ahead and drop the army scholarship except that i haven't yet received medical clearance from the navy. I don't want to risk being denied by the navy, and being without either scholarship. My question is, can i "accept" both at the same time? I need to respond to the navy within about 20 days or else its gone. Of course once i found out about the medical i would drop one of them.
