Not all sixth forms make their subject specific results easy to find. You might need to ask if it's not on their website. DS3 is taking chemistry A level. I still think he would be better off taking physics but what do I know? 
DS3 was up early and has done some history revision already. Two of his topics don't have published revision guides or text books, WW1 and America, which is a bit of a pain. He has a 4 hour revision session on history at school on Tuesday which will be useful. (Plus 2 hours English language beforehand.)
You must start thinking of yourself soon, sost. I don't like the idea of you delaying treatment, but I understand why you have.
