Here's some good tips to make moving and living on campus a lot easier:
TV/Entertainment: If you have roommates, each of you can pitch in to buy a small TV, like 30" or 40" should be enough, and at the end of the year whoever keeps it can just pay the money back to the others. As for other entertainment, like I said earlier bringing an older console is a great idea, newer ones are a bit more iffy since if they break it's a significant amount of money being lost. Another advantage is that more people will be familiar with older consoles and will be less hesitant about joining for games. Also, you won't need to bring a ton of movies since you're more than likely to have unlimited free wifi on campus to download
torrented legally purchased movies to your hearts content.
A nice deck of cards is also a great thing to have as they make for great evenings with alcohol. Just being able to relax around the table with some drinks and play a few rounds of poker is a great way to spend time. Bringing board games is also always appreciated, both when sober and when inebriated. Games like Cards Against Humanity, bananagrams and the like (basically
srk1214's post) are great ways to invite people over and get to meet them. The best entertainment in college/university is with other people, and breaking the ice is important. The better you get at that the easier the next 4 years of your life will be.
Bedsheets: Some dorms provide them, but it's better to bring your own since university ones will likely be shit tier. Probably bring 2 sets and swap them each week. Good sleep makes for good marks. It's also best to bring your own pillow.
Cookware: Buy a decent pot and a decent frying pan or cast iron. Between the two of those you should be able to make a ton of different meals on the cheap. As for glasses, cups, plates and the like, it's best to bring 1 or 2 of each. Even if you get a meal plan, cooking your own meals is always the best way to go. It costs less, it's healthier and being able to cook is a life skill and getting as much practice as you can is great. Also it's a great way to make friends because who doesn't like good food? You can also impress girls/guys with your cooking, so there's that. Your school might also have a small grocery store that accepts meal plans so it might not even have to be an out of the way trip to buy groceries.
Clothing: Don't bring all your clothes! Seriously, the dorms aren't that big, pack maybe 10-15 shirts (not including dress shirts), 5-8 pairs of shorts and 5 pairs of jeans. Throw in a couple sweaters, jackets or whatever based on the weather of the area you're in and you're good to go. Also make sure you bring enough underwear and socks.
Miscellaneous: Sometimes a safe is worth bringing, especially if you have valuables like jewellery. A small safe isn't
too expensive, but again it's entirely optional. Things can go missing during a party, and if you're worried about something like that then a safe is a great option. Alternatively a lockbox is a solid option as well. Cellphone chargers are important, though nowadays it's really not so hard to bum one from your roommates. A fan is invaluable during the early parts of the year when summers just ending, or if you live in a muggy area. Dorms aren't always air conditioned so having a fan can be the difference between waking up in sweat and waking up well rested and ready to seize the day. A desk lamp is also good to have, though your room might come with one. House sandals are pretty good to have as well, though you can always just walk around in socks.
**This part pertains to drugs and alcohol and sex**
It isn't the greatest idea in the world to bring a bong to your dorms, but most people probably don't care about drug use. The stoners will love you and congrats, you just added a cool little group of friends to your life. If your roommates don't want drugs in the house, just leave your drug related items at home or somewhere else. That being said, drugs are a fun way to socialize and are a great complementary addition to any of the the aforementioned activities. Avoid hard drugs like cocaine, heroin and learn your limit. No one cares how much you smoke, it's not cool to green out or pass out. Just make sure to keep an open mind about these things. If you don't feel comfortable taking them, say no. If you are okay with them but it's your first time, let the people around you know so that they know not to let you do too much.
When it comes to alcohol the same basic rules apply. If your roommates don't want alcohol in the house, respect that. You can drink at pretty much every residence building on campus, so it's not like it kills the fun. Don't drink during exam times, unless it's to celebrate. Drinking away the misery is just setting yourself up to fail. Learn your limits, taking 4 shots and not making an ass of yourself is better than 12 and throwing up. The best parties are the ones you can walk away from without cringing. If you are going to be drinking, always have water on hand. Also if you see someone who looks like they're going to pass out/throw up, make sure they're okay. Get them some water and bread, and tell them to lie down on their side. Another important thing to remember:
you can not consent when you're not sober. I shouldn't even have to mention that, but dumb fucking people always seem to forget.
And lastly the issue of sex and school. To be honest, this doesn't really have to do with "moving in", though I feel like it's worth knowing anyway. Sex isn't as hard to find as you think, and it's better to be safe than sorry. So make sure to bring condoms with you, though you're student center might also have free ones. Some schools also provide kits which have the basic information and things you need to safely have sex. It's not a social taboo like a lot of high schools treat it as, just make sure you and your partner are both mentally and physically prepared for it. If one of you aren't ready, just wait. Blue balls sucks, but so does fucking up a relationship because you couldn't wait to smash privates.
