After completing this “assignment”，Lucas decided he wanted to go out and play some basketball and then jammed out on his guitar.He may only be 15，but he sets his own schedule.He has shown he is responsible when it comes to this. Last summer，my wife needed to develop a website for her new business.We had looked into some services online，but my son insisted he knew how to do it.We decided to give him a try，but when we saw the final results，we were floored.We could not believe a 15­year­old child created this professional­looking site. I could not be happier with our decision to send Lucas to an online school.He is learning far more than he would be at his public school.He is well­behaved and respectful，and I don't worry who he is hanging out with.I'm grateful we had this opportunity.If you never considered online school an option，you may want to start looking into it.It could be the change your child needs to be successful.
