Seriously DON'T DO IT!!!!!
I am currently in my 3rd year studying pharmacy, the competition for pre reg places is fierce.
There are already too many pharmacy students for a sector that is facing major cuts.
If I knew 2 years ago, what I know now, I would have transferred into a different degree.
I don't know if it is just my uni or all of them, but they are also making the course harder and harder every year, introducing new extra exams with 70% pass marks that weren't necessary for the year above us etc.
Having said all this it is entirely up to you, but personally I wish I could go back in time and tell my 18 year old self to something much more enjoyable.
