Just looking for opinions please, my son has asked to go to 'maths club' like his friend does after a bit of digging it seems to be kumon which I know nothing about. On paper it looks very good but pricey. My Son is 6 nearly 7 and enjoys maths and is apparently borderline meeting/exceeding expectation.
Does anyone have experience of kumon and if so good or bad? Just worried I'd sign him up and he may put him off maths
Thanks in advance
