This is not a trivial subject. Nevertheless, I feel completely confident in my newfound knowledge of it. Not only that, but I am very motivated to keep going with the rest of the specialization now.
The material is interesting and new, on that part the instructor is doing a good job.
What is really VERY annoying about this course is the fact that in case you have questions/problems relating anything of the course material and you (as said by the instructor) post them to the discussion forums, there is COMPLETELY NO REPLY neither from the instructor, nor from the Coursera.
There were obvious mistakes in one of the quizzes and lots of students were posting and discussing this in the forums (as this was actually preventing students from passing the course), but there was no answer whatsoever.
I find this very unprofessional, especially because of the fact that this was a paid course. I do not know (and I also do not care) who is responsible for this - Coursera or the instructors, but this is something that should not be present in any of the courses on Coursera.
I liked the first course very much, but the mentioned part of the second course was so annoying that I really would not recommend taking this course to new students.
Sorry.
