General Marking Instructions This in the ONLY mark scheme released for this session . Note: Please use a personal courier service when sending sample materials to TLs unless postal services can be guaranteed. Record the costs on your examiner claim form. 1. Follow the markscheme provided, do not use decimals or fractions and mark only in RED . 2. Where a mark is awarded, a tick ( 9 ) should be placed in the text at the precise point where it becomes clear that the candidate deserves the mark. 3. Sometimes, careful consideration is required to decide whether or not to award a mark. In these cases write a brief annotation in the left hand margin to explain your decision. You are encouraged to write comments where it helps clarity, especially for moderation and re-marking. 4. Unexplained symbols or personal codes/notations on their own are unacceptable. 5. Record subtotals (where applicable) in the right-hand margin against the part of the answer to which they refer (next to the mark allocation for Section A). Do not circle sub-totals. Circle the total mark for the question in the right-hand margin opposite the last line of the answer. 6. For Section B, show a mark for each part question (a), (b), etc. 7. Where an answer to a part question is worth no marks, put a zero in the right-hand margin. 8. Section A: Add together the total for each question and write it in the Examiner column on the cover sheet. Section B: Insert the total for each question in the Examiner column on the cover sheet. Total: Add up the marks awarded and enter this in the box marked TOTAL in the Examiner column. 9. After entering the marks on the cover sheet, check your addition to ensure that you have not made an error. Check also that you have transferred the marks correctly to the cover sheet. We have script checking and a note of all clerical errors may be given in feedback to examiners. 10. Every page and every question must have an indication that you have marked it. Do this by writing your initials on each page where you have made no other mark. 11. If a candidate has attempted more than the prescribed number of questions within a paper or section of a paper, mark only the required number of answers in the order in which they are presented in the script, unless the candidate has indicated the questions to be marked on the cover sheet . Make a comment to this effect in the left hand margin.
