This course as much content in it and it's difficult to have an holistic idea how it all fits together. Some videos are taught having the same problem like, for example, some tools/themes are presented without us knowing what they are for. E.g., Chi-squared test and null hypothesis. Only after a while we understand their use. This bring a lot of overhead to us who are learning.
Some videos seem to have been re-worked over time and present cuts or jumps.
As for assignments, they should be better worked because some questions are not clear or misleading regarding the criteria that you want to evaluate.
For example, I already reported that in Question 2. and 3. of the assignment for the 3rd week. The example you give is a short introduction with two problems: 1) "I did the website", which can make the participant not to be at ease to criticize and 2) we're no evaluating the participant performance but the website. Next, you ask us to rewrite the introduction, which we do with those two problems in mind. Now, when we do the peer review we realize that you're expecting for us to rate the new introduction based on having "early prototype" and "user feedback". The original problems just seem not to count. Only by chance you can eventually write the new introduction touching the points that count for grading.
