Your eCampus should include PHYS 201 in the course list. Click on that course. On the course home page on the left hand side there is a link Mastering Physics Homework. Click on it. You then will be in Mastering Physics. The first time you access Mastering Physics you will be led through the registration process. You will need an access code that came with your textbook or that you can purchase online, or you can use the free tiral period.
