Check out bus services for yourself; is there any info on the uni website about travel or anyone to contact? What about if you need to stay late to study in a library and travel in the dark or attend social events? You would think there's some common sense gone into having accommodation remote from campus.
If it's reasonable, you could try bus for part of the journey then get off and walk. Otherwise I'd also suggest bike (if you meant e-scooter private ones aren't currently legal), but overall you've got to consider how much you'd be carrying and the weather; do you want to arriving soaking wet with sweat in summer and rain in winter?
