What students say about data-science

Lots of resources online such as the online library as well as one in real life to visit at any time. The city itself hasn't got much going on which is probably the worst aspect but it's definitely still lively for a night out and has its perks as everything is so close together. Nearby is hundreds of amazing landscapes that make for a good hike; if you're an outdoor person this is the place for you. There's also hundreds of clubs that are very welcoming and easy to sign up for and of course the nightlife is full of pubs and a great club that you'll see everyone at from Wednesday to Saturday. There's so many courses that go from really specific to much broader so there's something for everyone and on my course at least there's a good mix of written work and course work.

What students say about data-science

I had my Msc in Dental Technology at Cardiff Metropolitan University, and I had a great time. The faculty was ever ready to listen and help navigate me in the right direction. The International Students' office were very prompt in responding to emails and issues. Materials required for my practicals were always sent to me in time. This made me choose them again for my PhD. I am in my first year, and I am enjoying the programme. The graduate Staff are always willing to help with any difficulty or challenge. My supervisors are very helpful and showed so much empathy and understanding when I lost my spouse in December 2025. They moved our meetings to accommodate my emotions. There is support for mental health and other issues. I have not had any issues with any of their services or support, hence I cannot give any advice on what should be improved

What students say about data-science

Best aspects would definitely be the people and the location. By the beach but with safe and lively night life, which in my opinion is important for most undergrad students, also the welsh are lovely and friendly. It depends on the area but overall the city feels extremely safe which was important for me. Some of the buildings on the old campus (singleton) look a bit run-down especially when the sun isn't out so it might be worth them revamping some buildings to make certain parts look less depressing. But again thats only a few, and the walk to campus is lovely especially as theres a massive park/green space right next to campus, with a 2 minute detour taking you right to the beach. Can't say too much on the students' union because it looks good but i havent really engaged with it. They always have some sort of event going on but honestly i havent been to many, so maybe the events could be more engaging so more people including myself would go.

There are lots of resources and study help around the campus which is very helpful. My favourite feature is the outdoor study pods which are great in the summer for enjoying the nice weather and getting work done. I think one of the improvements that could be made is having more outdoor areas

What students say about data-science

Great location, lovely staff, diverse student body, lots of extras available to enhance your learning, employability and social life, e.g., free language courses, study skills, SU trips around Wales, etc. Some campus buildings are old and run down, and the gym can only be joined if you pay for the year upfront. I would say a lot of the societies are aimed at younger students, with socialising centred around alcohol. It's harder to find your place as a mature student!

The place is very small which is good because everything is in walking distance and you get a better sense of community while you study. The downside is that it is not as good as when I started in my first year of undergraduate, the student Union and its facilities have lost a lot of the charm that they had originally and its a shame that new students wont have as great of an experience that I had when I joined. Not only this but the town is definitely not as safe as it used to be when I first moved and that is very apparent but that isnt paticularly something that the university can fix.
