As a former grad that went to college 900 miles away from home seeing this makes me feel obligated to try and share what I can.

Don’ts

1. Skip class - this one’s been said a lot already and pretty straightforward so I don’t think I need to say much on it
2. Eat out EVERYday - sure a couple days here and there are fine especially since you’re still adjusting but a lot of that food isn’t good for you and gets expensive very quickly. I’m assuming there’s a kitchen at your apartment so I’d suggest getting some sort of setup going. If you don’t like/are not good at cooking there’s plenty of easy and simple things you can find on YouTube
3. Forcing yourself to be friends with your roommates - I’m not saying you can’t be friends with them, but if there’s an obvious difference in interest/hobbies/etc don’t feel like you have to force a friendship. Being able to live together peacefully is the most important part (sharing cleaning responsibilities, having or not having other people over at certain times maybe, respecting each other’s things/spaces, on and on)
4. Put too much pressure on yourself - Things aren’t always going to go as planned or expected but when don’t try to remember to not be so hard on yourself. You’re in a completely new environment and experience so there’s going to be a learning curve. Move at your own pace

Do’s

1. Have a routine - this one might take a while to figure out what works and what doesn’t but I feel like having a general schedule (built around your classes which you’re gonna go to) can bring some stability to a somewhat nerve-racking situation. Setting certain hours to study, work on papers, go to the gym, clean, etc helped to me be more efficient with what I was doing. Don’t forget to schedule in breaks too; burning yourself out isn’t going to help with anything
2. Take advantage of everything - any services/events/etc your school may offer use them. They are there for you so might as well get the most out of them while you can
3. Find a club - Any interest/hobbies/activities you may enjoy there’s probably a club for it. This is one of the easiest ways to get engaged and also meet new people. If you’re up for it feel free to try something completely new or that you wouldn’t normally do. Worst comes to worst you go once to see what it’s like and you don’t have to go back.

Hope that some of this might be of help. Best of luck to you
