My son's school doesn't offer so many classes. I
don't know how many high schools can offer those classes unless it's a private school. I do know a lot people send their kids to some weekend and summer college to get advanced education like this. But you have to pay ( a lot money to me and I don't think it's worth it). My son only take the classes his school offer and only 8 classes for each semester. I think this student doesn't go to a regular high school at all.
