While the videos and quizzes were easy to use, I had extreme difficulty using the DataCamp and could not find any tutorials that would answer my questions. Also, am unable to complete the course because of technical difficulties with RStudio. The course should have more online resources for those with little experience.

For Beginners, it is very difficult to understand the mechanism of how R works without the video guidance. Though reading is available, but it does not give a good understanding due to the complexities of R.

thanks for your effort to make videos, but this is the first time find a class that i can not submit my answer to check if it is correct or not before my account is upgraded. Disappoint to Coursera and Duke.

how to unenroll the course? Other courses have a three-dot button from which I can choose "unenrol", but I cannot do the same in this course, all I have is to "rate the course", which I did.

The course was not very helpful for me, as practical cases with R were poorly developed and the final data capstone project is badly formulated which makes it extremely difficult to pass.

This course is too theoretical and certainly not helpful to learn the R language. Better to watch free youtube videos on Stats and R. Just avoid this one.

Terrible course. There's no support at all for the Coursera version of the class. None of the concepts are explained and no support at all in the forums

The instructions for all the labs were confusing and left me lost. The pace was too quick, and I didn't feel like I learned anything.

Explanation of how to download the packages and do the Knit thing did not work for me, so I searched for a course explaining better

The lab instructions are terrible and the code used for this course is dependent on software libraries that are out of date.

Although the course is alright but the focus is not on R. Thus, the course is not suitable for people who want to learn R.

I have to drop this specialization because the so called 'nycflights' data set doesn't exist. What a waste of time

Speed is very fast for a basic level student. The data explanation and correlation demonstrated is not clear.

There's no point in auditing the course since you don't get access to the answers

the introduction with R is extremely confused for someone who is from scratch

Manque des fichiers pour travailler les labs (datasets)

There isn't a support to help you with doubts ...

I do not understand the directions make no sense

Quiero darme de baja a este curso por favor

could not run labs. useless without it

Peer reviews were overwhelming

Instructions are out of date.

Very poor technical support!

Too many explanations

Not as advertised.
