DS is home from maths 3 (edexcel). He says it took a bit longer than paper 3, but went well. So far, he only knows of 1 mark for certain that he has dropped across all 3 papers, but I'm sure the examiner will find the others!
Anyway, its done now and time to focus on Chemistry today/ tomorrow morning and then onto Physics for Friday. The end is very much in sight and he is struggling to keep the momentum.
