Haha, I would be on the "gifted but cba" list at GCSE - I could've probs got all A* but I only got 1, and now I've barely scraped into uni.
1 resit? In total I've probably done over 20. I've sat the same Mechanics paper 3 times, got increasingly low marks each time. If you only have to do 1, you're doing pretty well, that's all I'm saying :)
