This is the teacher with an absolutely amazing gift of being able to talk their entire class to sleep. Anyone can struggle with a subject and still have some fun in class, as I have seen before. Snoozers, though, are not interested in having fun. They're there to teach. That is all. They're the teachers that almost every student dreads. These types of teachers are relatively easy to identify since they normally don't raise their voice above a certain octave range, rarely interact with the class, tend to not ask if anyone is confused, and if your brain is strong enough, you may be able to witness the weaker-minded students falling asleep on their desks or at the very least having droopy eyelids. As long as you can figure out the material and manage to stay awake, you're good to go. Good luck!
