Accounting and finance aren't really that different; they don't do a pure Accountancy course (I'm pretty sure) so it's a bit of a mix anyway.
Put what you want to do, the usual crap (go to the PS forum, I'm not a helper there so they'll do better) and so on. You've got the grades, so don't worry about that. Certain universities have admitted they don't pay too much attention to the PS though...
