DS is in Year 12 and taking Chem, Physics, Maths and Economics. The last 3 are all going well but Chem he seems to find particularly difficult.
He wants to study Chemical Engineering at Uni so Chemistry A level is important!
He recently did an ISA and was v disappointed to get 10/15.
He achieved a C in his mock exam but wants to do much better for the University he has his heart set on.
He is a very hard worker but as it's completely Greek to me I can't help him. He has AS so gets very frustrated when things don't go his way 
We have Parents Evening in a couple of weeks but wondered if anyone could recommend ant books or online support?
