I didn't barely go to any seminars.
I'm not being arrogant, most of them aren't very useful: first year work is fairly easy; loudest students not always the brightest; PhD students (etc.) are rarely good teachers.
I thought you were cool Arkbar...
I've got two friends, both spent the *whole* first year literally going out *every* night... one went out the night before her exam! Anyway, neither did much work at all throughout the year.
One got a high 2:1/First in History and Politics.
The other failed 3 modules in Maths and had to take out a month over summer to learn/re-sit them all.
Moral of the story is, it depends. If you want to do really well at University, you need to be intelligent, interested in your subject, and attend most of the lectures and seminars. You can, however, be pretty successful from just 2 of these 3.
