Plus you can't do that because they will fire you on site. For example: if you are a science teacher and talk about memes and how much math sucks, one: students who wants to learn will report you
Two: The kids who will take the test and finish it will get a bad grade and their grade will be put into powerschool (that is where my teachers put their student's grades in, not sure about you guys) and will average up as a class and will be sent to the School District so uh e-e :X
I mean you can make learning fun, just teach the kids the materials and engage them with fun activities but remember depending on what subject you pick, requires to take notes so there will be days where it is a boring class. Just teach them and be a fun teacher
