In the third and final part of this series, students at Erith School and Townley Grammar face their GCSE mocks. At Erith, Denisa is striving to get A grades but the school is experiencing a teacher shortage. The head of science is trying to recruit a new teacher, but until then Denisa must prepare for her exams without a permanent teacher in her science class.

Two miles down the road at Townley, the students feel the pressure to get the top grades. Tanisha, 16, needs to get good GCSEs to stay on at Townley sixth form. But she is in competition with students from other schools, like Denisa, who also has her sights set on a sixth form place at the prestigious grammar school. And the headteachers of both the schools have an announcement: they are embarking on an ambitious plan to bring Erith and Townley into the same trust. Show less
