I'm only in first year so I'm kind of slacking with the course a bit while a can.. but when it comes down to it, it's a very demanding subject - even just in first year my workload has way exceeded what I thought it would, and it wasn't exactly like I was expecting it to be a walk in the park! However, as people have already said, it's definitely demanding rather than difficult. There's some aspects of the course I'll struggle to get my head round initially (mostly the chemistry), but once you've got it all understood it's working to balance your time well that seems to be key to being successful with pharmacy.
