Just keep telling yourself "it's only until (insert month here)". It can be difficult at first, people have more energy to party at the beginning of semesters, but soon it quiets down and everyone is just focused on studying. I had a noisy roommate once who always blared the TV, so I spent a lot of time in the library, and some workshop-type classrooms were open 24/7, so sometimes I'd sleep there. But like I said, the majority of college students are decent, hardworking people, so you should survive.
A few tips: always try and be civil, even when you're annoyed at your roommate's habits. Otherwise, if everyone's already stressed out about school, it can build into a negative atmosphere which is hard to escape from.
Keep nonperishable food, and anything you value, in your room.
Try and keep the place relatively tidy, but don't clean up other people's mess, otherwise they will expect you to do it again.
Communicate with your roommates if there is any specific time that you really need quiet, or when you want to use the bathroom, etc. Most people are accomodating.
If you really don't like your living situation, then you can always check into shared accomodation once you're there. I once rented a room in the house of an elderly couple-very quiet, and more comfortable.
Good Luck!
