schools, tuition and classes are really not the more the better now

nowadays, tuition, talent classes and schools are among the popular topics between parents. parents tends to give the best education for their children. Many would think that good education should be expensive but what I think is different. Money and fees should not be the parameters for quality of education. I have been working as assistant of a holiday class and I really felt that some of the student was really sick to these classes. Parent put too much pressure on them and they are really tired that they don't want to do any works again even it was a craft. Some parents sign up too many classes for their kids. How would you expect a five-years-old to learn art, craft, ballet, piano and many more. I felt like their kids aren't concentrate at all in the class and only do when I ask them to do with no initiative and a sense of done it without thinking on if they were doing well. Parents should make sure that their kids do well just in one or two field. I think its enough to just playing with neighbour and read some books at home. Maybe can learn a bit of foreign language as well.
