just links to a webpage... no support from the mentors no support form coursera... you can use your money more wisely..

The R Programming Environment is very buggy. Please tidy up the errors and make it more user-friendly.

Felt lost during the final, the course was not well suited to the end quiz

It covers basic concept of R, but less practices and tutoring

Tasks submision doesn't work. No reaction from lecturers

The course is poorly written.

Too basic.

exelente

There are bugs in using the coursera R programming online which doesn't allow you to upload the titanic data set in order to do an assignment. Also there wasn't enough information on how to do the assignments so you had to learn on your own in order to complete the quiz. In the end you can never fully complete the course because it wants you to manually submit the codes for the assignments even though you already did the automatic submission. Overall there's no help during this course so don't expect to get any.

Course should have videos to supplement material ( no point paying for a course that one has to read about , many resources exist online for that purpose). Additionally quiz question were not clear at times and made it frustrating. Manual submission did not work causing for me to redo the 1st assignment 3 times only to realize that automatic submission works, serious improvements should be made to this course!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Complete and utter waste of time and money! There is no conceptual or technical instruction involved in this course – it's all just swirl() lessons –:which are freely available and don't require a Coursera subscription by the way!:–. If you are hoping to learn and :understand: what you're doing look elsewhere! If you want to pay money for otherwise free, "type XYZ into the command line in order to do such and such" instructions, then you're in the right spot.

This courses uses automated grading of assignments directly from R, and the system is completely broken, so there is no way to proceed through the course. The course offers a workaround to the automated system, but the workaround is also broken. Many students report the same issue on the discussion board, and no solution has been offered yet. The course instructors are inaccessible, and Coursera technical support does not know what to do.

The content is great. Unfortunately the grading system is not functioning which means that one can't continue to the next step. I will be dropping out for this reason. I hope they fix it but it doesn't work now. Technical support was pleasant but not helpful. Based on the discussion forum, numerous other students felt the same way. If they fix it, I will sign up again, but right now I have to caution against it.

The material of this course is useful. However, the swirl course that accompanies it is plagued with issues that date back YEARS (there are posts on GitHub and the course's discussion board from 3+ years ago with the same unresolved or barely patched issues. If I hadn't already been reimbursed for this course by my employer, I would've given up on day one.

I had to drop out because of technical issues. A week 2 issue that is documented in the bulletin board had no clear resolution. After several months of trying to figure out the issue for weeks, I determined that the course wasn't worth extra time and money being spent.

The course doesn't prepare us well for the final exam. The expectations are too high for what is teached. I had to learn a lot by myself to complete it, which is not what I expect when I do a course. I don't recommend it to anyone.

The swirl lessons produce a code that causes you to fail the exam. Very poor course exam design! If anyone failed it was the instructors that failed to produce a user friendly course.

The assignment codes do not work and do not let me progress at all. All auth codes don't work, stuck in the same place after paying for the course with no certificate

You cannot complete one of the course assignments because swirl has a bug that prevents you from completing it. The bug has existed for years and has not been fixed.

Final assignment may not be reviewed for weeks. If you go on to capstone, issue could extent into months. Expect to use many external resources.

The classes are not super clear, and there really isn't much support for learners facing bugs.

All the issues with submission make this a waste of time.

lots of problem with swirl use unable to complete

Swirl autograder not working

the worst experience
