i want to categorically state here that i have seen a lot of 3rd class students with better skills, expertise and intelligence than our so called 1st class and 2:1 graduates (which may have been gotten through sorting or purchase).
The criteria f, A stitch in time they say, saves nine
Bros , i have also seen a lot of intelligent 2.1 and 1st class graduates too

Don't worry recruiters will sort out the genuine 2.1 from fake, don't loose sleep over that.

ok
A stich in time like you just said saves nine. So if you are still in school now, save yourself the strees; READ hard and you will get your 2.1 and 1st class.
All the best
