I have no problem wih the 4 hour classes (other than they are harder to teach because I need to overprepare each class in case we finish us a segment earlier than anticipated which will happen), but I have a 5 hour class that is really energy zapping! If the students fail to bring water or snacks for break, physiologically I lose them.....and I feel it is not in the best interest of anyone. I won't say YES to a 5 hour class again....too stressful on me, as well as the students (in my oppinion).
