I believe forcing a young child to do a subject after-school that they are not enjoying could cause more harm than good. Kids have a natural love of learning, but when forced will learn to hate the subject. I say this from experience. My son who has ADHD sat after school doing homework, at times for 3 hours and was developing a hate for school and learning. I spoke with his teacher and she limited him to 45 minutes a day. Not only did his grades improve, but so did his love for learning.
