Orientation week rocks. If you have an ounce of sanity in your brain, go to every sponsored event that remotely interests you. Nine out of ten of them are wicked exciting, and every person there is looking to make friends just as much as you are.
For a school that has a ton of motivated print journalism students, the school's paper is almost universally hated for its biased stories and lack of fact checking.
If you are a film/TV major, and legitimately want to be come out of this school with enough hands-on experience to survive in the real world, you need, NEED to be a part of the Emerson co-curriculars. Play your cards right, you can work on a TV set every weeknight, and a film set every weekend. As a freshman, I worked my way up to a director position of a TV show going up in Studio A, and at least four producing spots on film sets. By comparison, the earliest I would get into Studio A on the normal track would be some time junior year, and the earliest I would be producing anything film related would be my Film II either late sophomore or early junior year. Best of all, you just need an interest in the organization to become a part of it, as opposed to registration for class, and you'll get taught by a bunch of students who probably have more experience than most of the professors. In short, join co-curriculars.
Dating happens more frequently than students will ever admit, but everyone has at least two or three incidents where the girl/guy you've been scoping out in History of Media Arts will A) have a serious drug problem, B) will judge you permanently based on your taste in music, or C) will be gay. Don't let that disappoint you, but if it does, hey, there's about thirty other colleges in Boston to try.
Drugs happen at Emerson. A lot. If you're in a lecture class, I promise you at least three of the kids in the back row are high as kites. That said, it's also totally ignorable, should you want to stick to partying with booze, or skipping it altogether. Emerson kids have a good habit of not forcing any substance on anyone, save the natural peer pressure of a situation.
If you're doing your job right, sleep doesn't happen at Emerson. That said, it's now 2 AM, and you're hungry. You have a few options. New York Pizza is delicious, cheap, fast, and close; open until 1 AM on weekdays, 3 AM on weekends. Chinatown, though notoriously sketchy, has restaurants open 24/7. The food is hit or miss, depending on where you go, but it's almost all for dirt cheap. Find upperclassmen to give you their personal recommendations for takeout and delivery. Finally, your year is not complete without a trip to South Street Diner. Open until 5 AM, the food is amazing, the servers hip, and the clientele varying quantities of insane. You won't realize how much you missed it until you get there.
It's more than possible to spend your four years and never attend a greek function, but most freshman at least go to the SAE frat house in Allston for a stereotypical "college party", complete with cheap beer and frequent cop busts. That's not to say there's nothing worthwhile about the greek scene, but if you fit the type they're looking for, they'll find you, not you find them.
