The tutors often help the chlidren with the subjects that the student have studied that day .If you can listen to the teacher carefully in school,you don't have to waste the time after school.So i think the tutors are not very helpful.Students should have good habits in school so that their parents dong't have to waste the money to find a tutor .But you don't have a good habit,the tutor can help you reviw the subject.They are useful in the other hand.
Now the parents for the children please tutor.But some children don't like it .Because they want to have more time to play to relax himself . I think a family teachers can make children have more knowledge.So please family teacher is very good, I quite agree with you 。
