A-
Safety Above All Else
Honestly, you're not going to get arrested for drinking or anything. The whole policy is one of keeping students safe, making sure no one dies, and making sure Tufts isn't a police state. Some cops are really just absolutely ridiculous (a girl was pulled over in the middle of an intersection for not letting the cop go first), but all in all, police are there to make sure you're safe.
Very strict academically. So make sure you do your own work and you'll be fine. But that should be a given at a school like this.
No one's going to call your parents or tattle on you for little things. You're an adult and you can make your own decisions, good or bad. The administration will, however, occasionally email your parents about the increased consequences for attending a formerly permitted school-wide event.
