Hello, I've just worked how much i need to get an A in biology over all this year and its like 95% on both unit 4 and 5 which i don't think i'll be able to do. I got 71% in unit 2 last year, Im thinking about retaking it and trying to get higher and revising now (half term) for it because they take the highest mark anyway, but its literally like next Monday and I know that's really last minute. Does anyone know how I would go about entering myself into it? I know its possible because someone at my college did it last year but I have no idea how? Thanks
