For the first time in quite a few years I will be teaching general chemistry in two 75 minute meetings (Tuesday and Thursday) as opposed to the 'normal' three 50 minute meetings (Monday, Wednesday and Friday). From what I remember, I don’t like the Tuesday-Thursday classes. They are long and it is difficult to keep my attention that long let alone the students. Another negative is that it also means that I have to switch from my normal 4 exams + a final to 3 exams + a final. Wait a second, that means less grading for me…perhaps that is a positive and not a negative.
