I recently started this course, and I must say it was incredibly helpful and highly applicable in real-life professional situations. However, it's worth noting that one does need a substantial amount of time to successfully complete it.
I think the questions you ask in order to start an open task are sometimes not very clear. So giving an answer that makes sense to the question can be tricky sometimes. For the rest I think its good, although I think it could use more images/ video etc. I really enjoy the choice exercises, it really puts you in a situation.
