Hey! I go to Uni of Leeds now (different faculty).
There are so many shops for commercial shopping, there’s a shopping centre called Trinity in the city centre. Loads of new shops are opening too, flannels opened up not long ago. Food shopping wise, depends where you decide to live. Usually in headingly area, main shop is Sainsbury’s. Hyde park, Aldi. Woodhouse / city centre Morrisons / herons foods / Iceland.
Safety I would say it is safe! Theres been a few times where I’ve walked home from the city centre late. Never had any issues
Part time jobs- uni of Leeds offers some. The student union usually recruits people to work in co-op, fruity Friday (student night) etc…
Restaurants… so many! Leeds is a very international uni, naturally lots of new restaurants opening to meet their needs.
Unfortunately I cannot give any advice about the course itself or faculty as I am not a STEM student. Hope what I wrote helps!
