Both friends actually studied law. How they managed to upgrade from a 2.2 - 2.1 was to first-sit second and third year electives. Clearly, this is dependent on degree programmes, but almost all will have option modules along the way.
Lets assume you sit 3 x 5 modules in your undergraduate. 1st year doesnt count, so looking at the remaining 10, often 5 will be core and 5 elective. The way to get the grade up is to change electives.
They did it by changing, lets say, “enviromental law” to “EU law”. One friend (who now is a paralegal) went from a mark of 42 to 67 (I remember this, as he must have read his revision notes to me 10+ times!) which moved his average sufficiently to push him into the 2.2-2.1 realm (if my memory serves me correct, he was around the 59% mark). The second module then pushed him over the 60+ threshold and into a 2.1.
Unfortunately, I also have another friend (doing economics) who tried to same strategy, but didnt put enough (any) effort into the new modules and actually ended up failing them. So only do this if you are prepared to work hard.
Still, don’t get your hopes destroyed if even with a 2.1 you get rejected. I recently applied to a top 5 Investment Bank who previously had taken me up to an assessment centre. Since then, I have achieved a distinction in the examination component of my Msc and am awaiting the results of my thesis, but they still found fit to reject my application at the first hurdle. Sometimes you are the bug, sometimes you are the windshield! Whilst they would never admit it, the day, mood and time of receiving your application can really make the difference. I find being early is always good, or being approx 75% towards the deadline. If you are in the middle I tend to find they are somewhat harsh as there are still “a lot of applications left to review”.
Any way, good luck to all.
