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!

Really interesting course. The interactive coding sessions with swirl are especially useful. Would be great, if you provided sample solutions for the programming assignments, in particular for week 4.

Firstly the videos and the swirl practice were very good and I leart a lot from them. However, the assignments were very difficult. There is a huge gab beetwen the content of the course and the assigments. This course is not for beginners.

Better than the Data Scientist's toolbox, but not a great introduction to R. When I'm learning a new language, I don't want to know about data types and for loops. A detailed example showing the strengths of this language would be better.

I like the "Practical R Exercises in swirl". Very easy to understand. The "Discussion Forums" is very helpful.
However, the lectures are really boring. The assginments are not even related to the lectures. Not a beginner friendly course.

The quiz were far advance than the material and somewhat disjoint from the topics.The overall lecture is good but not sufficient for learning R, Week 3 and some parts of week 1 could have been explained far more better than it was done

Far too quickly moves from basics of R to advanced statistical programming. Needs better build up of skills. Swirl was useful, as the videos were essentially unhelpful. Many other better resources on introducing the content elsewhere.

The videos are not very engaging and the exercises demand skills way beyond the ones you can develop by simply following the course videos and swirl exercises. 2 stars because the challenges were engaging and based on real world data

Assignment is way too hard without any guidance - course as mentioned in their earlier lectures are meant to go online and ask. Even so, there is no way for beginners like us to understand what our questions should pinpoint to.

Too short, too simple, too theoretic.
I found of little interest the slides, partially interesting the swirl exercise, interesting the programming assignment.
I would like to have a longer course with more practical examples.

the course is absolutely not for beginner who has little knowledge of R even they are interested in data science specialization... this should be made clear to avoid waste of time, efforts and budget.. not worth subscription

Very disjointed and no clear progression. While it teaches the basic syntactic rules well enough, the functionality of R is explored in an ad hoc manner where the assignments have little to no relation to the week's lecture.

The assignments are way too difficult in comparison to what has been taught, the instructor already assumes we are from a CS background.
1 extra star just for swirl exercises, they were highly interactive and informative

it was a really difficult and un-informative experience, I didn't get any useful info through the lectures or reading notes. and the assignment were super hard to get through. my worst choice for a data science course.

It is just not a good course for a beginner, especially the assignment 2 is hard to understand. And hope this course can add a little bit material on statistical programming or machine learning session in the future.

There is not much of a relation between what the course gives (explains with the videos and with the SWIRL exercises) and the real exercices they ask to. Too difficult to follow by people new in the programming area.

The assignments were extremely difficult and there was not much of help directly from the videos or lecture material to learn and do smaller programming assignments that could be used when doing bigger assignments.

A huge lag between what is being taught, the swirl lessons, and the programming assignments. I'd definitely not recommend this course, unless and until you're already well versed with most of the functions in R.

The lessons were easy to understand. However, there is a huge gap between assignments and lesson videos. I personally believe it is not possible to do the assignments with the help of lectures and notes alone.

The course was not conceptual and is not helpful for students with no prior programming knowledge. The instructor just reads the slides and there is a huge gap between lectures and assignment. Not worth it.

Swirl is good. lecture are awful. Does not teach the necessary knowledge to be able to pass the assignments. The assignments feels real and the knowledge you need to learn somewhere else to pass is useful.

I don't think the course is setup for a beginner or a person who has never used R...very frustrated with needing to search the internet for help on everything that the course is supposed to be teaching me.

I don't feel good about this course. Please restructure it and teach it more incrementally, especially about loops, and extraction. The Assignment Instructions for the final week were not easily apparent.

Impossible leap of difficulty between assignments (especially Week 2) and lecture material. Poorly designed and in serious lack of guidance. However, the quizzes help consolidate knowledge from lectures.

The textbook is great for notes, but I would have loved to see more applicable examples of how to use the code. The instructor pretty much reads the textbook to you. Don't feel like I truly learned R.

Not a great course as said by the community. Most of the assignments are not even related to what is taught by the teacher and the way the teacher teaches makes learning R quite boring and cumbersome.

every time i watched the videos i ended up falling asleep. not at all engaging and professor makes it difficult to learn and build upon basic concepts. my only saving grace was prior exposure to r.
