The worst class I've taken from Coursera yet. Still it must be a lot of effort. So thank you.

Bad explanations (a lot of repetitions), poor slide quality in general, quizes often useless.

poorly organized and poorly presented, terms are constantly thrown out without explanations.

I would rather go through PPT than watching video clips. It makes me sleepy.

The explanations aren't clear enough, and the quizzes questions isn't clear

This course was below my expectation. I gained pretty basic knowledge.

Terrible vm, terrible video qualities. Not a Coursera type of course

Just an overview course, not going deep in development issues.

Not enough support from the community. Forum is not managed.

Explanations are not always very clear and understandable

I can also read from slides.

2* -- Because free content.

Too much technical jargon even in the first lesson!!!!

Confusing assignments, low quality teaching materials

The course was not well-prepared, it was superficial.

Badly teached course, very monotonic and superficial

Material quality was not good . It was too basic .

Superficial coverage of the topics. poor delivery

Instuctions for assignments are not very clear

step learning curve, lectures too long

Lecture quality needs to be improved

2 Star for good VM, good assignment.

Part about Spark isn't good

Not worth the money

Content is sad!!!

Very bad quality
