it's a really good course. Some of the modules are more interesting than others but you'll always get slightly dull modules whatever course you do. The first year isn't too tricky. Just go to all the lectures, labs and workshops and revise hard when it matters and you should be fine. As to whether it's a big step up from A level, well that depends how hard you're working for those. Nottingham's got a really good reputation for Pharmacy and it's geared towards getting you a decent job at the end of it, which is what uni courses should be about at the end of the day.
Second year gets quite a bit busier but you don't need to worry about that yet (I have 29 hours contact time this week - I had 9-5 today and do again tomorrow).
hope that helps
