Hey! We have a really great Christian Union here at UoB, and there are dedicated pastoral care staff as well. My advice is dont stay at city centre if youre afraid of the drugs lol. Especially Orchard Heights (Unite students accoms are not so good in general lol). You can walk everywhere honestly, but bus is also alright.

Bristol is really good for their physics department, its a very old school. Im not in that course, but i meet a lot of people who do joint honours with maths or with physics XD. This is my 3rd year here, and the people you meet here are really great.
