Amusingly I had a similar experience while holding a tutorial for math 2 at my university. After an hour a student asked me what the integral symbol is, as if she has never seen it before. Now I do not find this very tragic as I would gladly recap anything and working throughout my studies I know one might not be able to get through all of the content, but good luck studying when you are missing the basics to even understand the problem at hand.
