is it easy to make friends. ... Is it easy to get contact with the professors
generally speaking, both of these things are typical of any university for a person who's not going to hide in their room and is willing to email their lecturers - you don't need to worry
as far as the course goes, do some research. does it offer modules in cutting edge fields of computer science like ML? what are the graduate prospects? you can look at it's rankings and see it's a decent mid-tier university but that'll only tell you so much
