**Second Midterm early option.** Some of you have a Chemistry
midterm right after the Math 2030 midterm on Monday. We will allow a
group of students to start the Math midterm 10 minutes early, at 9:25,
and finish 10 minutes early, at 10:15. If you would like to take
advantage of this early option, please be there at 9:20 so that those
leaving early can all be seated together.
Everyone else will take the midterm from 9:35-10:25 as usual.

**Second Midterm.** The second midterm will be in class on Monday,
March 10. It will focus on sections 2.3-2.4 and 3.1-3.3. Although the
second midterm does not specifically focus on the older material
covered on the first midterm (sections 1.1-1.3 and 2.1-2.2), you will
still have to know it of course. In Section 2.4, you only need to know
the application we did in class (finite linear games). Here are some
practice problems:

- 2.3 #3, 8, 11, 17, 23, 25, 26, 33, 35, 36, 42.
- 2.4 #3, 31.
- 3.1 #13, 19, 23, 35.
- 3.2 #5, 15, 23.
- 3.3 #9, 11, 23, 25, 35, 43, 53, 62.
