I am also very eager for you to ask your own questions. However, if I am not sure I understand your question, I will ask you to try again until I do understand it. Try me and see. Don't be afraid to ask. Writing Writing is an essential form of communication, especially for subtle material like mathematics.
Some people think writing and mathematics are disjoint activities, but far from it.
So writing plays an important role in my courses. I have liked giving PDCs, and will probably give whatever replaces them. Since I like making up problems, I like making up tests. I think I write good ones. There seems to be a lot of misunderstanding these days by students about what tests are for.
