I got a 2.2, having worked hard for about 2.5yrs out of the four year course. I practically didn't attend university for the first year and a half however, so given this and extenuating circumstances I did ok to miss out on a 2.1 by just one exam question in the end. I also suffered from significant mental health problems which caused me to do things that put me at a huge disadvantage in 2nd year.
Given the considerable variation in difficulty of degrees depending on institution studied, subjects chosen, modules chosen etc a 2.2 doesn't mean your worse than everyone who has a 2.1. I would rather be a high 2.2 Oxford graduate in pure maths or theoretical physics than a first from Bangor in Politics and Finance.
