Firstly u must not confuse undergrad med vs post doc research
University ranking is all abt the post doc research and faculty research
Nothing to do with quality of undergrads, especially fee paying foreigner undergrad
While imperial ucl r good for local british, it is quite easy for sinkie to enter as fee paying international
Only oxbridge is harder than
nus or
ntu med for sinkie
So if im looking med, at the undergrad calibre i would place
Oxbridge higher, than
nus/
ntu. Then the rest is chui
Lousy A levels results. No straight As
Then again, med degree after graduation nobody cares
So wont affect ur chances
Hence for highly ranked london
