By the PhD Students for the PhD Students. That's what ticked for me. A thorough course with deep insights into the details of approaching a research problem. Amazing course. Highly recommended.
I think it is a decent course to understand how the peer review process work. However, it does not really help to write a paper. I think some ideas are not applied to every field. In particular, telling students to look for the board of editors in a journal and adapt your results and how you express things accordingly, it is in my opinion a bit unethical. Moreover, I was expecting that the course will be taught by a professor, but instead, it is done by a group of PhDs, some of them in their first year of research. If they intend to target a PhD audience, this is clearly a drawback as some of them might know the same as you do. Finally, as some people already pointed out, the quality of the English of some of the instructor is not good. In particular, there are a couple of them that you can't barely understand. It would have been more useful if the full course is taught by the 2 of them that can actually speak good.
