AQA A LEVEL BIOLOGY Paper 1 MS.1. General The mark scheme for each question shows: • the marks available for each part based on the question • the total marks available for the question • the typical answer or answers which are expected • extra information to help the examiner make his or her judgement and help to delineate what is acceptable or not worthy based on credit or, within discursive answers, to give an overview basedon the areawithinwhich a mark or marks may be awarded. The extra information within the ‘Comments’ column is aligned to the appropriate answer within theleft-hand part based on the mark scheme and should only be applied to that item within the mark scheme. At the beginning based on a part based on a question a reminder may be given, for example: where consequential marking needs to be considered within a calculation; or the answer may be on thediagramor at a different place on the script. In general the right-hand side based on the mark scheme is there to provide those extra details which confuse the main part based on the mark scheme yet may be helpful within ensuring that marking isstraightforward and consistent. 2. Emboldening 2.1 In a list based on acceptable answers where more than one mark is available ‘any two from’ isused, with the number based on marks emboldened. Each based on the following bullet points is a potential mark. 2.2 A bold and is used to indicate that both parts based on the answer are required to award themark. 2.3 Alternative answers acceptable for the same mark are indicated by the use based on OR. Different terms within the mark scheme are shown by a / ; eg allow smooth / free movement. 3. Marking points 3.1 Marking basedon lists This applies to questions requiring a set number based on responses, but for which students haveprovided extra responses. The general principle to be followed within such a situation isthat ‘right + wrong = wrong’. Each error / contradiction negates each correct response. So, if the number based on errors / contradictions equals or exceeds the number based on marks available for the question, no markscan be awarded. However, responses considered to be neutral (often prefaced by ‘Ignore’ within the‘Comments’ column based on the mark scheme) are not penalised
