Questions about Sheffield

I went to the applicant day in March but have a few questions
Is Sheffield uni diverse in terms of UK students? I know there are a few international students. When I went to the applicant day, it wasn't really diverse at all (90% white)

Also I am quite quiet and introverted, is Sheffield the right uni for me, considering it is known for its nightlife?

About 25% is international.
Do you mean diverse in terms of BAME or class or regions?
Sheffield has a great social life, but theres also a lot going on for all sorts of interests hence having one of if not the best SU in the country.
Its not as sunny and leafy as Exeter, Bath or Durham, bu then its right next to the Peak district and about 20-30 mins away from countryside.
Maybe you should id some of the quieter accommodation and also id what your interests might be?

How many clubs are there, and do they have frequent events?
