Wondering if Biomedical Science and Biomedical Sciences - note the extra 's' - are being conflated
In UK they are quite different and lead to different career paths
In UK Biomedical Science is usually accredited to IBMS and is the career path to laboratory scientist in the NHS, eg beginning with running diagnostic tests etc. Entry grades are relatively modest and curriculum is regulated
Biomedical Sciences is a common route for folks who cant, or don't want to, go down the Medicine route. Entry grades can be close to Medicine and the career path is to medical research or (sometimes) post graduate medicine. Most intending to do research expect to do Masters and possibly PhD.
My daughter is looking at Biomedical Sciences and hopes to do medical research possibly around immunology or haematology, we went to Bristol, Manchester and Warwick - they are all pretty close IMO, each has its strengths. I think Dundee is in trouble, but don't quote me on that
Manchester seemed to have the largest cohorts and largest range of course choices and a lot of opportunity to engage with research institutes - great city, great location for international students, one of UKs main airports is nearby
Bristol is a little smaller, they place quite an emphasis on Chemistry with slightly less choice and slightly less connections compared to Manchester - again nice city, quite expensive (as in near London expensive) not so easy to get to from outside UK
Both these are city unis, you are in the heart of the city
Warwick is my daughters insurance choice - very impressed with the uni, its facilities and opportunities to engage with research early. Employability is one of the best in UK.
This is a campus uni, a bit remote from anything interesting, you will be in the Warwick bubble - which may or my not suit. Again not that easy to get to from outside UK (and be aware it is NOT in Warwick, its next to Coventry)
Of your 4 UK options I would say Manchester or Warwick are strong, depending on the student experience you are looking for
