So tonight, after school, when he should be playing football in the park with his mates, he will be working out what is to HNA if CXG is to DWH. The following day it will be maths, including some problems nasty enough to stump his 22-year-old cousin armed with an A-grade maths A-level. If Laurie completed all the extra homework he has been set, he would be spending the equivalent of at least another day a week at school. This is the most stressful year of his life to date, and inevitably one of the toughest of mine, too.
