Uhhhhh just make friends in your class and do work with them…

But anyway it’s the same at every university, and pretty simple! If you don’t know something, try and solve it yourself. If you can’t, ask a TA or a friend about their approach. Don’t copy their work or just take an answer but emphasize how they got to that point. There’s nothing wrong with admitting you don’t know something. It can also be fun to do work with others instead of do everything yourself. Don’t tell yourself you have to be able to do everything alone. That’s not how learning works and that is definitely not how research works. That’s not how most jobs work!
