There are quite a few issues with the final assignment of the Getting and Cleaning Data course. I feel this assignments lacks quality in contents, suffers from a flawed process and lack of attention by the moderator.

T​his course is terrible. Outdated videos (recorded in 2013!), impossible quiz questions, installing huge numbers of packages into R with no real support or feedback. Terrible waste of time.

The instructor did not devote his time to teaching. Slides were poorly prepared. Links are not working. Although many students have raised the issues, nothing has been done for years.

A​wfull outdated material. The packages mentioned do not work with the current RStudio version. The presentation sheets are protected (all pictures) instead of extractable text.

Doesn't worth the effort. You learn the most by searching online tools each time you encounter a problem while solving a quiz problem or following the steps the instructor did.

almost all the videos from week 1 are outdated making it impossible to follow the course,i will propably drop it,this is something that should be addressed by coursera.

The course material was not of much help. Felt lost while doing the assignments. The instructor keeps forgetting that this is a beginners level course

This entire program is an atrocious waste of time and resources. Get a book on Learning R from your local library and you'll be better off.

I may not able to submit the peer graded assignment. please help me to solve this. My progress is pending because of this assignment

all the practical things had to be learned by self learning instead of in the course. Peer graded assignment took for ever to pass

The worst! I don't recommend you to take any course from this institute. It is just wasting time and money.

Description of assignment questions is not clear. The expected answer from the questions are confusing.

The peer grading looks weird. I got a comment on my original work "seemed to be not written by me".

final project is terribly defined. Lecturers, Coursera, and Johns Hopkins should all be ashamed.

Very scattered and unfocused course. Sad to say that I learned very little from this one.

This is just because of the unclarity of the final assignment.

Terrible! Go to Data Camp and save a bunch of money!!!!

the learning way in this course was bad, to me

It is more about R rather than data science

Poor teaching! Almost a waste of time.

I don't think it's necessary lecture

lectures are too fast.dropping out.

Poorly constracted course!
