Okay.. so there is two coursework that we do: the open book and the practical. For the practical I got 37/45 (raw marks) which is internally assessed and for the open book, that is the one I am trying to find out as it is externally assessed . The open book is also out of 45 raw marks. On the results sheet it says for unit 2852/A I got 63/90. Now is there anyway I can work out the raw marks that I got from the open book? And how does the marking system work for courseworks for OCR salters? I need to know quickly so that I can decide which to re-sit. Thanks
