I have just been looking at the Edexcel schedule for the summer and it seems that C1 and M1 are on the same day at the same time this year. I appreciate many sit C1 in January but what about those doing both this summer? One at 9am and then held in 'quarantine' and sit the other immediately after? Do the school have the right to pick which they do first? 3 hours straight of exams?
