We will use iClickers in class. These must be the physical iClickers, not the iClicker app. The latter is not allowed, because use of cell phones during class can be very distracting.
iClickers can be obtained from the bookstore, or you may be able to buy a used one from another student.
The grades from iClicker use will be incorporated into the homework portion of the course grade.

Policies for exams are as follows.
The two midterms will be given during the normal class hours (12:30–2 pm), and will be in our normal classroom (Etcheverry 3107).
Generally, about a week before each exam, a sample exam will be distributed in class and posted on bCourses. This will usually be an exam from an earlier Math 113 class that I've taught. Sample exams should be used to get a general idea of the likely length of an exam and the general nature of questions to be asked (e.g., the balance between computational and more theoretical questions). However, one should not (for example) observe that a sample exam contains questions on material from Sections 1.5, 2.1, 2.7, 3.1, 3.4, etc., and expect to see questions from those sections on the actual exam.
Exams are cumulative, so the second midterm may have questions from material prior to the first midterm. Of course, the final exam will cover the whole course, but will have increased emphasis on the material not covered on the midterms.
Here is a link "How to lose marks on math exams" (by a former GSI Andrew Critch).
The Math Department maintains an archive of old exams (usually without answers). Here is the link for Math 113.
And finally, a word about regrades: Grade calculation errors are welcome for discussion or review. Whether this solution should be worth 4 or 5 points is not.
