RG has no significance for Pharmacy - all MPharm degrees are accredited by the GPhC and all qualify you as a Pharmacist.
The NHS are not going to ask 'which Uni' and neither will your future customers/patients.
So - forget all RG snobbishness, for Pharmacy its totally mindless.
Bath - as an example of a top STEM Uni that is not 'RG' - makes offers of ABB with an A in EPQ.
