As long as we agree that LED screens aren't necessary, but could be counter-productive, you can have a whiteboard. 🙂

I avoided using the term 'high school' - because the whole system is a bit different here in Germany. I went to a Gymnasium. That's 12-13 years of school. Then you choose a specialization and go to University. (Or don't)
The concept 'college' does not even exist here.
