no it doesn't matter up to the extent of learning as a pharmacy degree is taught to the standards of the RPSGB etc etc (you all know about that anyway!).
However, reputation wise then red brick universities can look better when employees look at you qualifications and where you got it from. I kniw for a fact from a pharmacy student a bradford that when they carry out pratical work and they get it wrong, they do not get marks deducted from their overall score.
However, the so called "better" unis deduct points for getting thigns wrong. Therefore, in theory, they should give out a better standard and higher quality pharmacist compared to someone who went to a university that wasn't as good in comparison.
I actually found this quite shocking at first but apparently it is true.
