Question about Coursera certificates & specializations

[spohara]

Do you guys watch all the videos or jump straight to the quizzes? I wish these coursera courses had more text instead of just videos.

For the IBM Data Science Professional track, I watched every video.  You can probably get away with lab then quiz for a lot of it(but might need to play the last 10 seconds of a video for 'completion', not sure).  For me I think I learn better mentally preparing first and getting a general idea of the topic, then doing the hands on.  But most of the true learning came from the labs.  Some of the introductory lessons don't have a lab, and some of the quizzes contain a little info from the video, but it was usually either common sense or covered in the lab anyhow.
