Professor consistently drops the ball and allows the AWS credits to expire inside this course. You cannot complete it as of 12/20/2019. Coursera is not able to fix this, Amazon says to talk to Coursera. Coursera says to talk to the Professor, and the Professor doesn't respond to his campus emails.

Never got added to the AWS student profile by the Professor and therefore couldn't submit first week assignment although I have emailed the Professor to add me in the Student Profile.

Coursera - you need to make it easier to unenroll / drop courses. My dashboard is cluttered with content I explored but decided not to pursue further, including this one,

I am really having a hard time understanding the instructor and the tasks given are hard since there is no help or little information provided.

this is not beginner course, very hard to listen without subtilties, and the aws lab its a disaster

No access to Amazon classroom. Impossible to pass the specialization.

communication isn't clear

Excellent course. Very well explained public/private key using gpg and Public Key Infrastructure with OpenSSL. Several links need to be updated.

This is a very intuitive and flexible course upon deadlines. The instructor has control over the course hence making understanding very simple

Excellent course on security, good teacher, good material and especially very good practical material.

I got the yearly subscription and didnt mind to spend time on this on top of other planned courses. I will not pay for this course. Don't get me wrong, the material is good and as a beginner I learnt a lot. But the general lack of maintenance for this course is not worth it to pay. Some other (free courses) has an active TA who at least takes care of the questions. Nobody answers anything here. But saying that, I still managed to finish the course with some common sense so its fine. I am kind of thankful too because the assignments kind of forced me to learn Linux. First exam had unexpected questions and some questions were not worded properly but I kind of got the hang of Prof Chow's style and managed to benefit from his teaching.
