The review and little quiz

Today in human geography with Mr. Schick we began class by reviewing over what we did last class with the video. I had previously looked on varacross so I knew we had a quiz I just had no idea what the quiz was on. but after we went over the video notes and turned them in, he said we had a quiz on the notes. Which in taking the quiz he was exactly right, the quiz just asked us the same questions that the paper did on Hans Rosling. However, he continued to talk about the demographic transitions like we had discussed it before which caused confusion. As far as I know, and I have never missed this class, we have never gone over this before, but he acts as though we did. I don't know if it is a mess up on my part or his part, but I do know that I have no idea what he is trying to get at when he talks about the stages and things. Like he will ask what is stage one? Well I have no idea and he seems to get frustrated when he respond in such ways but we never learned it, I even looked back in my blog after the quiz and my journal before the quiz and I couldn't find anything on these per say stages. That’s all we did in class, I am writing this in class now and that’s all we are doing in class.
