Marking in 2021

Notice board for errors and corrections in the Advanced solutions

  • Feb 8: The ‘add a student’ option isn’t working. We’re addressing the issue now. Meanwhile, the option for marking a script as missing *is* working (unlike previously).
    • Feb 11: This problem has now been fixed. Unfortunately the ‘missing script’ option *isn’t* in fact working (contrary to the above message), because it doesn’t save the entry; but it doesn’t matter because you can show that you’ve marked all the scripts you have by hitting ‘Yes, I’m done marking’.
  • Feb 7: The Advanced problems are named A1, A2, etc because this year (unusually) they’re all unique to the Advanced competition. But the portal doesn’t accept letters – just numbers; so on the portal the problems are called 11, 12, etc.
  • Feb 4: This year’s arrangements have been deeply affected by the pandemic, so please consult:


The marking coordinator is Neema Kotonya


  • Mon 25th January: final day for notifying us of your marker capacity.
  • Jan 25-29: week for allocation of schools to markers. During this week your page on the portal will show the contact details and script numbers of your school(s).
  • Feb 1-5: test week, so all Advanced scripts should have been scanned and uploaded (with lists of names) by the end of Friday 5th.
  • Feb 6-15: Marking takes place.
  • Monday 15th February: Deadline for uploading points to the portal
  • Monday 22 February: Advanced results announced
    • If you have been sent paper scripts with a stamped addressed envelope, please keep them with you till this day in case we need to include them in our shortlist; but on this day you can return them to the school.
