Instructions for Markers
  1. Check if the iGeo student numbers are on each sheet (on odd pages) before dividing up the Test.
  2. This test consists of 6 Sections.
  3. One whole Section per marker and double-checker. One Section per marker-pair who also perform double-checking for their Section. Some lengthy (more than 2 pages) Sections may be divided for two marker-pairs. The layout of the Marking Scheme follows this logic as much as possible.
  4. Check whether the answer continues outside the designated area, on the margins or as clearly marked on blank pages. No credits will be given to answers in the Resource Booklet.
  5. The maximum total mark is 90. The mark for each question is given in the left margin at the beginning of the question.
    There is a maximum of 15 marks for each Section.
  6. Get the hang of the full range of answers by reading through a few papers with your co-marker before you start your marking.
  7. These answers are not exhaustive. Credit any relevant answer.
  8. The Test uses two marking systems: point and level marking.
  9. Half marks can only be given where indicated.
  10. Mark only the required number of answers (reasons, examples, etc.). For instance, if the question asks for 2 reasons and there is more than 2, only the first 2 reasons should be marked.
  11. Please develop your own marking/correcting system (using +/-, x/0, √ marks), underlining, comments etc. to ease double-checking and sample marking.
  12. Put your mark next to the question number in the column on the left – it eases the work of the person who has to put the numbers into MS Excel.
  13. Please write down any inconsistencies of the Marking Scheme and additional answers or answers not accepted and hand them in after marking to improve the final Marking Scheme.
  14. The Moderators (Sue and Anu) will sample the marking of all teams.
