this is most likely in the high school level. what happens when you are in a class that you have very little to no knowledge about the subject? example is physics or pre calculus. it's been so long since i've been in high school and i'm totally lost with these subjects. how do subs deal with incidences such as these and still keep his/her head up about being "competent"? i dont want the teacher to come back one day and say the sub didnt teach the class anything blah blah blah. so any help on this area please share. thanks.
