Oh, ouch for your ds, BTM, that's very painful. You could try some of this which is ££ but does seem to work wonders. It's not a very big bottle, but perhaps you could use it on the worst bits? I bought some for ds1's Harry Potter scar after his face plant in July, and it's definitely helped the raised bit of the scar and also soothed some of the redness which wasn't going away. He's only been using for a week. As an interesting aside, I think it was developed by Natasha McElhone's husband, the doctor that died
but used to redo children's faces where they had been damaged.
Thanks for the info about the GCSE stuff, stropps, that's very interesting. I think you're right, it sounds like the Unis will have their work cut out comparing the different years as they go through the start of a new system. And 3 x 3hr exams for GCSE science? Wow - that's way more, are they expected to reproduce Gray's Anatomy? (I just typo'ed that Gary's Anatomy, snort). I had 2 x 3hr papers for my history A-level and that covered the whole of European political history from the end of the Napoleonic Wars to the start of the Great War, plus a huge chunk of Industrial Revolution.
Ok, gotta go now, boys are fighting. Sigh.
