My friends son received an A* in Biology and Chemistry in his A level mocks. His results came back as C. How does this happen? I used to be an A level teacher a decade ago so I know I’m out of touch but I can’t get my head around it. Straight A student all through his time at school. The school he attends is is very poorly performing, fairly deprived area. Is it the algorithm or the school. I feel so sorry for him and the others in this position.
