<p>I am new to mastering physics access kit. I know that I should input my homework answer through web, how exactly does it work?</p>
<p>what is course ID?</p>
<p>You register for the course with the course ID that the professor gave you. And then you can access all the assignments that they post. You click on the assignments and things should be pretty straightforward from there. Good luck!~</p>
