Hi,
I'm a current MSc Computer Science student at Warwick, it's my 4th year here as I decided to stay after doing my BSc in maths. Whilst it's not exactly the same course, the department has been great this year, great range of modules and well taught.
With regards to the university in general, I've had an amazing time here. The campus is great, I haven't spent much time in Cov but I've lived in Leamington for 3 years now, it's such a nice place to live, v pretty area and lots of stuff going on. The commute into campus can be annoying some times with the buses, but I've always found it was worth it to live in such a nice place.
My biggest piece of advice would be (if you haven't already) visit both universities and get a feel for the areas.
If you have any more specific questions about student life or the department, please let me know, I'd be happy to answer!
