Instructor Notes: are inputted by the instructor for the benefit of students. It is in this section the instructor will communicate to students any information not mentioned in class. It is the students responsibility to check this input regularly.

 

Chapter Topic, Assessments: Each Chapter title (notated in BLUE) is a  Power Point Presentations (if available)  and summarizes the lectures given in class. Assignments, Labs, Write-ups, and Quizzes are accessible here and are due as instructed in the syllabus. It is your responsibility to remain current on all content presented in class throughout the year. The corresponding exercises and assessments listed below are required to be completed by the Due Date listed. Failure to have these exercises completed by the due date may result in 0 points for the exercise. The exercise by the instructor when noted for completion. You will be able to access these exercise in class during lab time or anywhere there is internet access. Completing these assessments in a timely manner will enable you to have the maximum knowledge for an optimum score.

 

Additional Resources: ainstructor is absent the lessons below will be tend class on a given day use the presentations below to use as a resource for study. You are reminded that you are responsible for the information covered in the lecture. These presentations are simply a resource to help you stay current with the class. Remember, failure to keep current with class work will inhibit your ability to pass the class.
