 “Makeup” Test Policy: Approval for making up a missed test should be given prior to the
scheduled test. The makeup test must be taken within one week following the scheduled test.
Documentation is required for all make-ups. Except for extraordinary circumstances, approval
for a makeup test will not be granted if the scheduled test has already been given.


Attendance Policy:
Attendance is a requirement in this class and in the lab period. If you miss
a class or lab, you are responsible for making up any missed work. Attendance will be taken
each class and lab period. Attendance means RESPONSIBILITY – I look much more favorably
on students who have good attendance habits.

Late Homework Policy: Late hand written homework will be accepted but only limited credit
will be given. I consider late homework to be homework turned in later than 5:00 p.m. of the
day the assignment is due. The maximum number of points a student can receive for a late
homework is ten points lower than the minimum grade of all students who have turned in the
assignment on time. For example, if an assigned homework is worth 80 points and the lowest
score of the on-time assignments is 60/80, the maximum grade a student can receive for the
assignment is 50/80. No exceptions to this policy will be granted except for extreme circumstances 
that require official university documentation or a predetermined arrangement between the student
and myself that is done prior to the assignment due date. Late assignments must be turned in within
one class day of the assignment due date to obtain any credit. 

Laptop/Cell Phone/Electronic Device Policy: No cell phones, computers, or other electronic devices 
are to be used in this class when these devices are not being used in a way that is conducive for learning
what is being taught in class during a particular day or time. Determining what is conducive will be left
up to the instructor's discretion. The instructor retains the right to ask a student to leave class if they
exhibit this or any other behavior that is a distraction to learning for other students in the class.

Textbook Coverage: Chapters 2, 5-19 and other selected chapters as time permits.
