Which loan should I choose?

I recently applied for 3 loans for college. I was approved first for two loans, each of which were half of the amount I needed to pay my bill. Since that happened, I accepted them. Now, I was approved for the third loan, which provides the full amount of my bill. The problem is though that my bill is due on Wednesday, and for the third loan I still need to send them paperwork. So should I choose the third loan and risk not getting it in on time? or choose the other two loans and have more safety ?
