Any camping tips for me?

going on school camp next week.. this is a new school and their camps are very 'outdoorsy'! aka, no running water, toilets, electricity etc. we are pretty much going to be in the middle of nowhere in the freezing cold and cooking for ourselves for a week. we have to take all our food and plan meals etc. too. i have never done anything like this before! so if anyone has any tips for me that would be great! thanks :)
