Help with course.

Ive watched the webinar recorded it doesn't still say that I've completed it. 

also what is it with the three part pick and mix I mean like I've watched the video fall in love with the game there's no activity and it says to go this forum connect and learn. I've done the courses for week two aswell can anyone pls tell me how ill be done with the webinars and the videos like what do we have to do with it thanks. for it to be completed. I'm not understanding what's demanded from us in it.
