• Otherwise indicated, marks once gained cannot subsequently be lost, e.g. wrong working following a correct form of answer is ignored (isw)
• Where a candidate has misread a number in the question and used that value consistently throughout, provided that number does not alter the difficulty or the method required, award all marks earned and deduct just 1 mark for the misread
• Recovery within working is allowed, e.g. a notation error in the working where the following line of working makes the candidate's intent clear
• cao

• Generic Marking Principles must be applied by all examiners when marking candidate answers
• Generic Marking Principles


  • Marks must be awarded in line with the specific content of the mark scheme or the generic level descriptors for the question, the specific skills defined in the mark scheme or in the generic level descriptors for the question, and the standard of response required by a candidate as exemplified by the standardisation scripts
  • Marks awarded are always whole marks (not half marks, or other fractions)
  • Marks must be awarded positively: marks are awarded for correct/valid answers, as defined in the mark scheme. However, credit is given for valid answers which go beyond the scope of the syllabus and mark scheme, referring to your Team Leader as appropriate; marks are awarded when candidates clearly demonstrate what they know and can do; marks are not deducted for errors; marks are not deducted for omissions; answers should only be judged on the quality of spelling, punctuation and grammar when these features are specifically assessed by the question as indicated by the mark scheme. The meaning, however, should be unambiguous
  • Rules must be applied consistently, e.g. in situations where candidates have not followed instructions or in the application of generic level descriptors
  • Marks should be awarded using the full range of marks defined in the mark scheme for the question (however; the use of the full mark range may be limited according to the quality of the candidate responses seen)
  • Marks awarded are based solely on the requirements as defined in the mark scheme. Marks should not be awarded with grade thresholds or grade descriptors in mind

  • Unless a particular method has been specified in the question, full marks may be awarded for any correct method. However, if a calculation is required then no marks will be awarded for a scale drawing
  • Unless specified in the question, answers may be given as fractions, decimals or in standard form. Ignore superfluous zeros, provided that the degree of accuracy is not affected
  • Allow alternative conventions for notation if used consistently throughout the paper, e.g. commas being used as decimal points
  • Unless otherwise indicated, marks once gained cannot subsequently be lost, e.g. wrong working following a correct form of answer is ignored (isw)
  • Where a candidate has misread a number in the question and used that value consistently throughout, provided that number does not alter the difficulty or the method required, award all marks earned and deduct just 1 mark for the misread
  • Recovery within working is allowed, e.g. a notation error in the working where the following line of working makes the candidate's intent clear
