In 2020 there were an exceptional number of appeals to upgrade student IBDP scores by teachers following the cancellation of exams due to the coronavirus pandemic. In compiling the 2020 league table we were forced to set a deadline to not take any more upgrades. GIIS increased their average IBDP score to 37.35 from 100+ students after our deadline. We are pleased to record this exceptional result here, but have been unable to upgrade their League Table position because we would otherwise have to recontact hundreds of other schools. We congratulate GIIS on such a high score, which would have otherwise lifted them into the top 50.
