When i went for my interview after applying for pharmacy through ucas extra, there was a seperate interview for successful first year pharmaceutical sciences students. I think there was about 10 of em and im guessing quite alot of em got in!
This was @ LJMU, try ringing up unis who do this kinda thing, and ask how many successful students got onto pharmacy this year...
This should give you an idea whether its worth it or not...
Plus i think you MIGHT be able to move onto the 2nd yr, because both first years are so similar...if you're following me...Not sure about this at all tho!!
Just ring up everywhere!
