Harry, we have our GCSE Mock Exams at the same time as challenge 8. Would you be able to tell us tentative deadlines so my team can plan around this obstacle and meet for a few hours before the first deadline and be able to get full marks? Last year, near challenges 6-8, first deadline went down from 12 hours to 8 hours to 4 hours, so it would help to know so that we can plan our meetings.
