It doesnt actually matter where you study Pharmacy - its an accredited degree with an identical syllabus at each Uni. There is therefore no 'better' Uni.
The NHS wont ask 'which Uni' and neither will your future patients. When was the last time you asked a nurse, a dentist, a physio or a pharmacist where they trained - they are qualified professionals and that is all that matters.
'London snobbery' has resulted in a silly level of applications at KCL and UCL - they now have to use an extra online test to weed folk out. In contrast, at most other Unis, if you meet the entry requirements, and can briefly explain' why Pharmacy' in your PS, you will get an interview. So why does anyone bother with KCL or UCL - especially given their growing reputation for messing applicants about, delaying decisions - or not making them at all - not answering emails, and generally behaving in a shabby and arrogant manner. Instead you could apply to a Uni that actually wants you.
