Still a bit confused about double and triple! It was my understanding that if DS opted for triple science, he'd sit 9 exams next summer (Y11), which I thought would be P1, 2 & 3; C1, 2 & 3 and B1, 2 & 3... which beggars the question why don't they do the '1's along with the Double Science pupils right now (who are doing Core)? Are they the same exam??
Then DS trips home announcing they've been told that the whole class has 'done well' in a prac- good-oh, says I, which prac? Presumably an end-of-Y10 internal exam? But no. Apparently it goes towards his actual presumably Chemistry GCSE mark- which he allegedly sits next summer. 
I don't geddit!
Anyone?!
