Ok so I think I'm going to resit core 1 and mechanics, then I've also got core 3 and core 4 to come so that gives me a possible 254 marks, I need 180 so I can mess up on 74 marks.
I'm thinking of doing core 2 and stats too but I think it might be too much, if I did stats I'd have to go over the whole course again and core 2 is going to be the hardest to improve on because I've already got 80 and it's quite a bit harder than mechanics and core 1 but I could always just chance it?
