Excellent course! I already knew a lot about R - but this class helped me solidify what I already knew, taught me lots of new tricks, and now I have a certificate that says I know `something' about R!

Very challenging, but good course. I've been programming in R for over a year, but there were still some things for me to pick up in this class. Assignments were a challenge, but satisfying to tackle.

R tutorials and assignments are great - however, had to spend more time figuring out Git than I spent on R assignments...

They don't give enough inputs and instructions to complete the assignments, unless they could offer addicional material.

it was too fast for me and i was expecting to study R programming from scratch..and many things were very fast.

I found the jump in difficulty for the first assignment too great. This seems to be a view reflected elsewhere.

The instructions were not satisfactory, and there is a large gap between the assignment and the skills taught.

This course was so convoluted and not practical that it made me lose complete interest in the specialization.

Fix the assignments so they match the course content. This is unfair to the people who pay for this service.

This course presumes you are a programmer to begin with. I tried to take the class to learn how to program.

Assignments do not match up well with the lessons and the lessons are BAD. They are not educational.

Too much of a jump from the previous course. Exercises much too complex relative to the lessons.

You can't do assignments using the lecture materials. Need A LOT of time to finish this course.

There is a huge disconnect between the lectures and what is asked in the homework assignments.

Gap between the theory and the practical assignment is huge. For a beginner is not an option!

This course is not for beginner. If you look for beginner course for R, look else where.
