I understand this couse is certificate-free and an email is sent in place of a certificate, but at least make sure to address the email to the verified name, not to the account name. Now I received an email I can't even use as a confirmation of course completion.

As far as the course content is concerned, I appreciated the time spent while learning and even though it is an introductory course, it succeeds at delivering even complex concepts about medicine to a vast audience.

I give 5 stars to the course, but my final grade is 4 stars because of the certificate issue.

Overall, a very useful amount of insight packed into a pretty enjoyable format.

An area of improvement for the next iteration would be to mix the excellent story-telling in Weeks 5 & 6 with the deeper, more technical material of the earlier weeks. Each end of the spectrum (detailed reasons for space being a harsh environment <---> fluffier storytelling with great NASA footage) was useful...it was just a bit thick in details and could bog down a mind in the middle weeks.

Thank you for bringing all of this knowledge together....

An enjoyable way to spend a few hours and to learn in the process. The instructors give some good, understandable examples of some of the concepts involved in conceptualizing the challenges of humans living in an environment they didn't evolve to inhabit. Overall, taking the course is time well spent.

Good general overview of the medical issues encountered in space travel. Lectureres went quite fast at times and sometimes spents only a few seconds on a topic that was included in the homework. Overall, enjoyed the course and learned a lot.

Although I liked the course and they did a great job but after 6 weeks of working, I was not able to print my certificate!!! it gives me an error of not finding the page!!!!!

A great course covering almost all the topics of aerospace medicine briefly and a good head start in the career.

Well done! Suchbnice overview!! Great opportunity! It would be 5 stars if there could be a certificate!!

Excelente curso, muy interesante, con explicaciones muy cercanas y fáciles de asimilar.
