To start, you should make an account in the website. After the activation, you can login to your account and then you can choose the courses you like from the course selection panel.
From now on, 2 video files would be available each week from the courses you already have taken. You can see them in the homework part.
If you have any questions about the course content, contact your professor from this section (the homework section)
If you have any questions, feel free to contact us on firstname.lastname@example.org .
