You do all your assignments here at our website. You have unlimited attempts in answering questions for each assignment, as long as you are doing the assignment before the due date. The best way to get help is attending the optional Zoom Office hours we can share screens and work together on assignments. It is best to start ahead of time, getting most done first, then show up for help on the harder questions.

In addition, you can receive extra credit at this website by doing the optional work in the interactive chapters.

Always plan to complete assignments at least a full day before the due date so if you run into any problems, you have an extra day. If you choose to do homework/assignments after office hours, you are on your own, whatever problems might arise, including last-minute internet difficulties.

There is a well-known law in engineering physics called Murphy's Law. The simple statement of this law is "If something can go wrong, it will." Planning to complete your assignments in advance gives you time to get help if you run into trouble.
