go to clubs and events. they're a great way to make friends, especially if you go to one actually related to your interests. like, i found most of my closest friends from college in the video game club. even if it's not your first choice of things you want to do, you'll meet a lot of people by going to these gatherings and it's the best way to break into a friend group.
don't start out with too big of a workload. trust me, taking more work than you're prepared for in college is a terrible idea and will make your grades worse than they would have been if you had taken less classes/easier classes. allow yourself to ease into the different environment rather than throwing everything at yourself at once, because you might collapse under the pressure.
the bus will be your new best friend (as long as you have a bus stop semi-nearby). learn the routes and the times it comes, because it's the best mode of transportation if you don't have easy access to a car (like at my school, where the parking is like 87869 miles from the dorms >_>)
ask questions and talk to your professors if you need help. they'll appreciate it and be much more likely to be helpful to you if you actually show that you care about the class even if you actually don't. also, building a good relationship with a professor can lead to future opportunities and connections.
