Question Paper Log Number P76378A
, NOTES ON MARKING PRINCIPLES
1 Types of mark
M marks: method marks
A marks: accuracy marks
B marks: unconditional accuracy marks (independent of M marks)
2 Abbreviations
cao – correct answer only ft – follow through
isw – ignore subsequent working SC: special case
oe – or equivalent (and appropriate) dep – dependent
indep - independent
3 No working
If no working is shown then correct answers normally score full marks
If no working is shown then incorrect (even though nearly correct) answers score no marks.
4 With working
If there is a wrong answer indicated on the answer line always check the working in the body of the script (and on any
diagrams), and award any marks appropriate from the mark scheme.
If working is crossed out and still legible, then it should be given any appropriate marks, as long as it has not been
replaced by alternative work.
If it is clear from the working that the “correct” answer has been obtained from incorrect working, award 0 marks
If there is no answer on the answer line then check the working for an obvious answer.
Any case of suspected misread loses A (and B) marks on that part, but can gain the M marks. Discuss each of these
situations with your Team Leader.
If there is a choice of methods shown, then no marks should be awarded, unless the answer on the answer line makes
clear the method that has been used.
