Question

Has the course started yet?
If so, how can I get

Answer 1

I have asked edX both on FB and have e-mailed them too. Will let you know if I get a reply.

Answer 2

Now, I think we can press the button of 'View course'　just after Log-in that didn't exist before. The button being pressed, the web page opened will tell us what to do.
Thank you anyway.

Answer 3

Did you look at the course info yukkunn?

Answer 4

Yes, I did. When I posted the question, the button that leads to course info hadn't existed.
Now, I can understand what I should do. Thank you.
