Recievied a U in biology

We did the biology 2015 Ocr papers and I revised so much but the exam just focused on biodiversity and classification . Literally the whole paper . Feeling very down because I got a B and an A in psychology so my predicted grades for them will be okay but for biology will be so low . & Everyone else found paper 2 so they all cheated so now they all I got good grades and urgh just feel like giving up . I've only got paper 1 of biology back yet but I know paper 2 went just as bad 😭😭😭😣
