**Text**: * A concrete introduction to higher algebra*, Lindsay Childs, 2nd ed.
We will plan to cover most of the first 12 chapters, and then several additional chapters,
chosen partly based on class interest.

**Quizzes**: Each Thursday we will have a short in-class quiz.

**Tests**: We will have two in-class hour exams.
[Sometimes an exam just doesn't go well; who knows why! To help take this into
account, your lowest hour exam will be replaced by the final
exam percentage IF that improves your average (so as not to punish someone
whose final does not go well).]

**Final Exam**: 7:30am to 9:30am Friday, Dec. 15, in our usual room.
Everyone must take the final exam;
do not make plans to leave town before the
final. You are expected to
arrange your personal and work schedules to
allow you to take the final
exam at the scheduled time. No student will be
allowed to take the final exam early.
### Grade Scales, Averages and Semester Grades

There are three hour exams.
In addition, there are weekly quizzes, homework
and the Final Exam. Your Semester Grade
is determined by averaging your grades on these items with the following
weights:

hour exams average 100 points each
quiz average worth 100 points
homework average worth 100 points
Final Exam worth 200 points
Total 600 points

**Departmental grading appeals policy**: Students who believe their
academic evaluation has been prejudiced or capricious have recourse for
appeals to (in order) the instructor, the departmental chair, the departmental
appeals committee, and the college appeals committee.
