I think that schools should have a sign-up sheet, and whatever students and/or parents want an avatar can sign up and just pay extra. The reason is for when you can't come to school because you are sick or are on vacation, you can still "come to school" whether you are there or not. That way you could always be at school and learn the information, and the only thing you would have to do after you come back is to make up all the tests, quizzes, and stuff like that. Also, you would never be counted absent from school. But what would be even cooler is if the avatar had a small printer type of thing so that the teacher could just slip the test or quiz in the slot, the student could take that test, and then the student could sent it back. But that would be kind of hard to do, so that might not happen just yet. But the avatar thing is cool!
