My son gained a 4 in his GCSE Maths exam. He is disappointed with his result and would like to retake it in November. The college he is starting at won't fund it as he didn't fail it. Which means we need to fund it privately. Before he retakes it in November I would like to get him some tutoring to ensure he succeeds in gaining a higher grade. Does anyone have any experience of this and can point me in the right direction please ?
