Home Computers Some students decide to purchase a computer while

taking this course.

Since you have computers available to you at the labs, it might be advisable to wait until later in the course, when you have more experience and information about your options.

You do need to be prepared to spend lots of time in the computer labs or on your home or business computer to do the homework for this class.

Assignments There will be nine assignments. Home work will be worth

50% of course grade Be prepared to spend 10-20 hrs per week to work on

assignments. It is important not to get behind in turning in assignments. If you do get behind, we still want you to do the assignment,

so it is better to turn in a late assignment than to skip it. However, late assignments will be severely penalized, and

may not be graded except to note that the assignment was turned in.

Assignments that you turn in should be your own work. It is fine to talk to other students and to get assistance in how

to do something, but you should not ask your fellow students to actually do the work for you.
