Instructions for the remote administration of Midterm Zero are here. Please read them carefully, by Monday 4 January!

Information for Midterm 0 (as given on Friday 8 January and Friday 15 January):

- No calculators or notes will be allowed.
- There will be 10 problems, all review, some from Math 251 and some from earlier.
- All problems are short answer; no work need be shown.
- They are all or nothing: no partial credit.
- Notation counts. If the only thing wrong with an answer is poor notation (such as in the examples here), it still gets no credit.
- Total time: 20 minutes.
- Two chances; I will give the higher score. Extra credit for getting all problems right on both of them.
