This is one of the two worst trainings I have taken in the recent 15 years, courses, subjects, units of universities, Coursera, Udemy, Pluralsight, etc.. all included.
Why? A student comes to learn about things. They generally hope, by implication, to be taught by qualified staff who know what they are talking about and who know their courses. These people are not here. The people in the videos are not answering questions. Those who answer questions here don't know much about the course. Students have to give them links, after already telling them section titles. Even when they replied, students would have to try hard to bring them to the course material under discussion - otherwise, they wrote about something else.
Furthermore, they are definitely not subject experts who are qualified answer such highly technical subject matters. They can give students links over the Internet, in most cases. Then, why do students come here? Youtube and Internet would be enough.
Number 3, the course is terribly created, scripts mostly read to students by machine-generated voices. Materials were mostly quite randomly put together. Later materials cannot find earlier discusions for foundational discussions. There were many concepts not explained, discussions where prior foundations could not be found.
If this is not enough, after students have tried to finish the course by the due date, there is a lab that has been denying students' access for over three weeks. Three weeks! Not enough to resolve an issue. I have personally contacted the 'staff' here, Qwiklabs support, Coursera support, multiple times, trying to find a way through or around. None of them cares. They asked students to wait. It's been three weeks!!! The course itself is only three weeks. Students come to this lab at about the end of the second week. The only outcome is that students will have to pay more. I told them of this. How did they help? Nothing. No workaround.
I have gotten so many apologies that I realize they are mostly copied and pasted and sent to me. The small merit this course has is that there are videos and support staff replied, often by scratching the surface.
In short, the course is a perfect representation of the greed, greed, and more greed of the training provider. Productivity, profit and scale of operations are their objectives. Not students' education and welfare.
