The materiel covered in the course was great, but more assignments instead of quizzes should be added.

Materials (video and written) only partially prepare the student for the quizzes and course projects.

Not as clear and straightforward as R Programming. But definitely a worthwhile course to look at.

While the available content is good, I expected this course to take me to a more detailed level.

Ups and Downs.

Some presented functions are deprecated according to official documentation...

Course project was really vague and it took me 3 days to understand what is really wanted

The lessons are good, but they do not prepare you for the tests or end-of-course project.

The assignments required A LOT of help outside the information provided in the lectures.

Not as good as the other courses offered by this specialisation. In need of an update!!

Need more lectures on R packages and newly added packages like reshape, dplyr etc.

The evaluation part of the course needs some fixing. Otherwise, very good course!

Course touches points very superficially. Need to have better reference material.

More examples of code running in parallel with the course work will be helpful.

This course really gets you working with R. The swirl exercises are great.

very nicely made course providing a good hands on with R language. Thanks!

​The letrue should be updated. Most of the URL address is not accessible

The course isn't that hard but there is a lot of content to assimilate.

Topics were OK but the focus on R and no other tools is frustrating

The course was good but a bit too versatile for such hard quizzes.

Vague instructions in many of the quizes and the final assignment.

It would be better if for each function there were more examples.

Average. Not useful even to tackle its own quizes and assignment.

Explanation could be more elaborated like the earlier courses

Not well explained.... Previous module was better structured.

Useful.

Too much talking. Not enough integrated exercises.
