Can anyone give feedback on Bath, Reading and Durham (Queens Campus)?
hellsbells it's difficult to give reliable information about universities generally, and wholesale "Oh such & such a university is good" is probably not very valuable. What sorts of specifics do you want information on? Are you interested in particular subjects or disciplines or degree programmes? Is it the accommodation, or the welfare provision, or the nightlife?
The thing is, that the UK is blessed with pretty much universally excellent universities. This is because (unlike the US for example) we have a national system of QA (quality assurance) wit the requirement that we academics review fitness of provision every year, and our External Examiners (senior academics from other universities) have to see all our paperwork related to courses & modules and assessment of those courses. Most Departments have at least 2 External Examiners, and often more depending on size of student body.
Then there are 5 yearly QAA reviews. And the NSS (whatever it's worth ...) All of this information is in the public domain via the Higher Education Funding Council (HEFCE) and the Higher Education Statistics Something or other (HESA).
So you can be pretty sure that wherever a student goes, they'll get a good value education in general terms. But it's the specifics that are generally what applicants are looking for, and what they comment on in things like the NSS.
So it's the specifics that we can help you with here, as there are several academics who post regularly here (I post when I have a deadline looming -- terrible procrastination and no will power!) Or we can direct you to other expert sources of information.
