I think Edexcel made a mistake while issuing my result (if that's possible) because there's no way that I would actually get U in unit 1 and 2 of Biology as most of answers are exactly the same as in the Mark Scheme . Now I'm thinking to use one of their services , But I'm not sure which one should I use , Clerical check , ATS copy or should I go for remarking straight away , Any help on this problem would be greatly appreciated
