The problems of many children with learning, for example, with maths, can be associated with a lack of an individual approach to the child or with a not very competent teacher. Now there are ways to solve these problems thanks to online schools like https://brighterly.com/. I think that online lessons are generally very convenient, while you can find a teacher with whom the child will feel comfortable studying. At the same time, there are no age restrictions, and even if the child is of preschool age, he can already start doing maths.
