A 22-year-old Greg James appears on BBC Breakfast to discuss his experience retaking a GCSE maths exam alongside other Radio 1 DJs (Scott Mills, Edith Bowman, Comedy Dave, Grimmy and others). Greg brought a lucky plastic duck, walked out an hour early, and predicts he'll get a U grade, while reflecting on how much harder exams are than people think—and how he'll have to face the results on Jo Whiley's show later.
