How are you going to be assessed for the practical component?
Are you resitting in order to apply for Medicine in the future? Bear in mind that the NHS is not a nice environment in which to work in as a doctor, and for much of your career you won't even have a choice as to where you will be working. The pay isn't anywhere near as much as in the USA, or even in Australia. So you are left with a very prestigious degree and job title, but not the career you might have thought you were getting yourself in for.
I personally rate MPharm as a better course than Medicine, although Hospital Medicine is a much more rewarding career over working in a shop.
