Impossible:) Everybody is drinking in the college, and it is rather funny to be the only one sober, but if you say that you don't drink, to make you drunk become everyone's goal number one.
Not really. It's your choice. If you don't want to, you don't have to. However it's always nice to wind down with your friends every once in awhile. College is suppose to be a social experience, no point being all uptight and strict. You don't have to drink. Just don't be a shut-in and you'll have a great time.
Student life is the most wonderful time. It is such an amazing feeling that you can do everything. But don't forget about your studies. Because then you will be like sitting on writing a dissertation and not understanding what they want from you. I spent so much time finding a good service with a custom dissertation that it would be better for me to study.
