My DS is in year 11 and doing his GCSEs this summer. He's working really hard and should do well. However I've just realised his spelling is atrocious! Is it possible to get penalised for bad spelling and, if so, how many marks would be awarded for it? Another question is that if it is the case that he could potentially lose marks for something as little as spelling how can I help him improve it? At 15 I doubt he would appriciate my help but even so I would like him to have every oppourtunity at doing well even if he won't accept it!
