DS13 has just started year 9 (his school do a 3 year GCSE course) and he has just found out he is in set 3 - he is top set for everything else - and it has knocked his confidence.
Are there any websites or books that anyone could recommend that might help him progress? I don't want anything too intensive just something to help him in class and boost his confidence. He wants to aim to get to set 2 by the end of the year and has asked me to help him but I am not sure of the best approach. He is normally happy to coast along with minimal effort so I don't want to dampen his new found enthusiasm!!
