I was lazy and didn't realise that you actually do have to put the work in at University to get the grades, unlike at school. I ended first year with a 2.2 (57%).
I graduated last year with a first. So yes, it is very doable. First year doesn't count towards your overall degree classification, but just make sure you don't go into 2nd year with this attitude and work hard from the off, and i'm sure you'll achieve at least a 2.1.
Also, I secured a good placement abroad. I don't think they take your first year grades into account that much. I'm sure they place more importance on your application, interview and experience.
Good luck.
