You are getting good advice here Collin. Please use it.
The only thing I want to add is do what you can to get some good sleep. It's hard. I was there as was a lot of people here. You need a solid sleep. Also try and eat properly. It helps keep your mind fresh and you don't faulter as much.
The person that you will spend the most time with in your life is yourself, so make yourself as interesting as possible.
