Ah that means DS will have some company when he's plugging away at further maths (if he decides to do it). Someone had told him it was just them and the Germans would be in school that week too but he had thought they meant some sort of exchange trip :).
Has done virtually no further maths but I think he intends to do a paper after physics has finished and see how he gets on - its the AQA and not meant to be as different/hard as the Ad maths one so we'll see. Also if he gets a C it wouldn't look out of his place among his other grades, unlike 8/9 students, May depend on how the paper 2 GCSE goes and whether he's got the stamina to keep going after the 19th !! He may do it as his new best mate in house is doing it too so they may stay in school and have a maths binge together. Good to see him enjoying an academic subject - after 11 years of struggle in the classroom and being worse than useless at sport its such a change for him to be doing well at something so I can see why he is enjoying it.
