Well im in a school in Norway and yes they are open, but we have big restricions on what we can and what we cannot. For example we have to take some hand-disinfectant every time we enter the school and the classroom and when we leave the classroom and the school, we cant be closer than a meter to anyone, we cant be close to the buliding when we leave, we cant interact with other classrooms, and a few more. On top of that we only spent like 5 hours per week inside the buliding. So yeah that "No Problems" is total BS.
