Man how are people getting marks of 80%+, let alone 90%+, does that relate to maths degrees or something?
Just that doing my zoology degree, 80% is something practically unknown and certainly 80%+ is basically impossible. As one lecturer put it "If you're asking me why you got 74% and if it's possible to get percentages like 80% or more. If I could literally take your assignment and publish it in a mainstream peer reviewed journal with no alterations, I'd give you 80%, so don't moan about your 74% percent, that's a very good mark, in all my time lecturing here I have only once given 80%, that was for a diss and that was just something else."
I've not known anyone on my course who's gotten over 78% (They dish that out as a standard percentage for high 1st, I've got it once.) for anything assignments or exams wise.
Anyway for me, anything 2:1 is fine, though 65%+ is a result where I'd not think any negative, 2:2 would be bad for me.
