I'm pleased with ds1's approach: he doesn't seem stressed and seems to be doing "enough".
He has all his exams this summer (not done modular courses etc.), so has 17 exams, but most are just 1hr. Some subjects, eg Eng Lang and Maths he doesn't need to revise for, just complete the practice work set for homework. He is on track for very high targets for all subjects.
This Easter hols in total he has about 15 hours of set homework to complete and is doing 10 hours of planned revision. (He does focused 30 min slots.) Also going into school for 5 hrs one day for workshops.
So is the average mumsnet child doing more or less than this?
