When should I apply for an on-campus job?

There are 2 on-campus jobs I was interested in. One is a library assistant and the other is a payroll intern. Should I wait until I actually get to campus in late August or would it be fine to just apply now?

If the application is online and they’re looking to fill positions for the fall term, I’d apply now. I applied for my first job freshman year before getting to campus, then interviewed when I was there.

Good advice. I guess there’s nothing wrong with applying now
