I think a lot of GCSEs are moving away from coursework this year, so there may be less for current year 10s than previous ones. Ds, now in year 11 did no coursework until the end of year 10 when he had a geography field trip to write up. So far in year 11 he's done an English essay & that's about it so far.
so what subjects still have coursework? Science/Maths don't, English/Art/DT/Geography do - what about Languages/ICT/history/RE? It seems that if you choose the right subjects you might not get too much coursework.
I know ds's English teacher thought they'd get better marks doing their coursework later rather than earlier, (but they did do some speaking & listening early on, I wasn't sure that was exactly coursework though - more like science ISAs - they did 3 of those at the end of year 10 too).
