hey,
well if this person dislike his/her course then he/she should really speak to somebody and try and change to a course he/she will like. my friend chose computing and she disliked it and so moved to ICT and she's much happier.
and it really depends on the course tbh. like if you have tutorial then that may be the only time this person won't be in the same class as you but if you're doing the same course then you'll be with each other quite a lot.
