I know this is obvious, but apply for any and all scholarships your university/school/department/major offer, and any others you can find that are maybe niche or specific to you/your field/your interests. Get a campus job! Campus jobs will be flexible to accommodate your class schedule, otherwise get a local service industry job that you ideally can walk/bike to. But seriously, don’t let a job take away from your academics - no point in paying for a class if you’re gonna fail.
