For an introductory course with no prerequisites, the assignments should cover material that has been introduced in lectures. Non-introductory and advanced courses in R can require students to look outside of lectures for completing relatively complex problems.

BEWARE. If you are someone who is new to more advanced math or to any sort of coding, this course will be very confusing, totally unpractical, and you'll walk away not feeling like you've really learned how to use R in a real way.

I was incredibly disappointed.

Wow. I cannot believe how difficult that last week was. No explanation for how to go about it just a learn it in your own time. As soon as the $49 USD is taken out of my account the difficulty is raised considerably. Cannot believe I paid for this subject.

This course is poorly structured and the lessons don't prepare you in any way to complete the assignments. Don't waste your money taking this course and find something else. Johns Hopkins University should be embarrassed to have their name on this course.

The lectures are good for basic understanding, but there are no sample programs in order to understand their real world application. And the assignments are not at all for beginners. There is a huge gap between the content and the assignments.

To be honest, this is the most terrible course that I have ever had on Coursera. The courses are not well organized, and the assignment has little to do with the videos, which means students have to learn by themselves to finish the assignment

Poorly organized and managed. Each week of this course should have been broken down into individual 4 week courses. I have 20 years software development experience, and I can tell you this is too much information to cram into a single class.

The new platform Sucks!!!

The people who just want to learn for free and not purchase a certificate are barred from attempting the quizzes unlike the old platform. Not being able to take the quizzes completely ruins the learning experience.

You don't have to go through the videos which I found painful because of the instructor's voice. The textbook includes everything in the videos. However, there was no application for the videos and textbook in the quizzes and assignments.

I really wanted to learn R in my current Mac iOS environment, in a Linux/Unix environment. I only see here the course offered in Windows environment in archaic MS-DOS environment? I am not interested in that. Hence I unenrolled.

The course is poorly designed with link between assignment and course material being so wide. This sometimes creates frustration of quitting the course. This made me think whether this course was designed to learn R or make money.

Somewhere during the second week there is a gap in coding that I could not overcome and this ruined the whole interest in pursuing the course because in order to overcome it I had to cheat. I don't feel like I am learning anymore.

This class is a travesty in learning R. The lessons are misguided and do not prepare you for the overwhelmingly difficult homework assignments needed to complete the course. I would not recommend this to anyone trying to learn R.

The topic which was discussed by the professor can't match with the assignments and quiz.

I think the video of teaching should add more elements of practice, so that it would fit people with no basic knowledge of programming more.

There is a significant gap between the lectures and assignments. For someone with very limited programming background, this posed a great hindrance to my ability to use the resources provided to be successful on the assignments.

Possibly the least well structured class ever. Also, not made for people to actually learn how to program in R. It is sad that I paid for this, and ended up going to another resource to learn... and it was much much easier.

Not a class for the beginning programmer. The lectures do not line up with the assignments, and if you don't have programming experience, you could easily spend 10-20 hours/week figuring out how to finish the assignments.

The ask in the fist assignment was not formulated correctly. Felt the class needed more hands on learning. Although the lectures were clear and concise, going back to them really didn't help me with the assignments.

I think there is a total mis-match between the lesson material and the assignments. The amount of hours one needs to search the internet to augment the training. The recommended text doesn't even come close in

I don't feel like I really learned R from this course. I felt like they just made me aware of some features. Also, there was vast difference between the course lectures, swirl and actual assignments.

Huge gap between what is taught in the course and the assignements given which makes learning extremely difficult even for those who have had some kind of hands on experience with computer programming.

The assignments had nothing to do with the lectures. The teachers do a poor job of explaining basic concepts and theories. The class is a lot more advanced than the class description makes it seem.

The assignments are too hard for the lessons that we had it made me frustrating, after week 2 I completely lost and didn't know what should I do .

I really don't recommend this course for beginners

Sadly the assignments are not possible with just the course itsself since they cover different material.

If I have to research the assignments myself why take the course in the first place?

This course is the worst course that I have taken so far. I am not happy with the course content and the way that the lecturer uses to teach this course. I really want to refund my money!
