I'm not actually HE-ing (though did think about it), but need advice from HE-ers whose DC have done/are doing Chemistry GCSE. My DS is nine and is completely obsessed with Chemistry (he has AS, and Chemistry is one of his two obsessions). He wants to do a GCSE in it and would, according to his school science teacher, pass it standing on his head - but for the fact that 20 percent of the marks are derived from lab work/practicals. As we don't know any tame Chemists (we've tried our local university, to no avail - apparently they're not insured for nine-year-olds), we're rather stuck. Has anyone managed to overcome this problem? I'd be very grateful for any bright ideas. My husband and I are both academics, but strictly on the Arts side, so can't help much!
