Last year, my high schooler had very little homework. There were 4 total classes, only 3 of which required any work. Much of the homework got completed during the last 20 minutes of class.
This year, it's a different story. There are 5 academic classes and 2 electives. There is almost always homework in 2 of the classes and often in all 5 academic classes. My teenager is highly motivated, has honors and AP classes, and spends 2-5 hours a night doing homework. I'm not complaining. I think this is a good thing.
