You can still dislike your roommate, but it is to both your advantages to make every effort to get along amicably. If you really can't stand your roommate, you can look into moving somewhere else, or depending upon the agreement, kick out your roommate and look for another more suited individual.
On the Roommate Pairs page of the NYU Housing Portal, a registrant can create a new roommate pair using the “Create Pair” button in the lower left corner. On the following page, they will create a Roommate Pairing name and password, which they should share with their prospective roommate.
We encourage you to take the Roommate Agreement seriously - schedule time to sit down with your roommate and talk through each of the points. It is important that you are honest and clear with your roommate during this time, and don't just say what you think your roommate wants to hear!
If you are planning on becoming roommates with your best friend in college, this is your time to revisit that decision or be sure you create strong boundaries with your friends to limit any tension or miscommunication. Always remember to think deeply before making any long term decisions like this one.
Incoming first-years do not choose their roommates.
Many colleges have a matching system to pair you with your future roommate. If they do not, they might do it manually within their housing department. If you are going to an in-state college or going to a college with someone you know, you have the opportunity to choose your future roommate if you so wish.
