The contents of this course are really practical and to the point. The examples and notebooks are also up to date and are very useful. i really recommend this course if you want to start with Spark.

Nice course. Learned the basics of a lot of different topics. Nice to do a large Data Science project in the last part. So you can apply all learned theory

Very very basic. Far away from advance. I did more than the whole course in just one lecture at my university (LSE). And that lecture at the university did not assume that we already got experience with Spark or python. I still give three stars because it is still quite ok, just far away from advanced.

Good material. Hard to understand the instructor's English. No professionally presented. Assignments are too easy, and we didn't get good, meaningful practice. Quizzes often address information that either the instructor failed to present well, if at all, or made mistakes on.

I felt that, for a course labelled as 'Advanced', there were too many trivial questions in the quizzes and too much hand-holding in the programming assignments. That being said I did enjoy the course and learned quite a lot and look forward to the next one in the specialisation.

The course was great, the material and the assignments.
IBM Watson platform was easy to use.
But I can't see how this course is included in the "advanced" data science specialization.
Honestly I was expecting a more advanced course. But we'll see with the next ones.

The content was OK, but I have expected more. Probably it was too basic for me. I would have been happy to see some more real life examples, like when to use the different statistics to solve real problems, not only the theoretical ones.

Gives you a great understanding about the fundamentals and how apache spark works. However, some exercises and files are outdated and it will not take you the amount of time the course info indicate, fow me it was less than half of it

A detailed explanation on the trade off of different approaches that can be used in Big Data but there is not enough examples of manipulating big datasets

I believe that the assignments of this course should have been a bit more rigorous. Also, there should have a been a bit more focus on Apache Spark.

The course content is amazing but the instructor's accent is very difficult to understand and in some videos subtitles in English weren't available.

give lot of details about pyspark like basics.
its getting hectic with just the small details given in videos.
videos needs to be changed and updated

Good introductory course, however it would be better if the assignments were more involved rather than having the code typed out already for us.

Some of the content in the video should have been updated due to the change of interface. Had some difficulty setting up the environment.

Topics can be taught a bit more slowly, it was a bit difficult for me to understand. Otherwise, the content covered was very helpful!

The content was okay, but it is pretty basic. There is legacy from previous versions of the course that needs better transitions

The functions we need to complete looks quite messy, it'a little bit overwhelming especially for people who start with spark.

I felt the course is out of date and have worked on these classes to update it so that I can run the video classes again

the assignment is required to be in sparkaql functions however the course is just using spark with built in functions

Too many legacy issues. Would be better to start a new course altogether and maintain same syntax,etc.
por George H•

Analytically very simple, and fails to explain much of the syntax needed for the assignments.

The videos have not been updated to fix the errors (there is just a hint for a correct code)
