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!
Very challenging, but good course. I've been programming in R for over a year, but there were still some things for me to pick up in this class. Assignments were a challenge, but satisfying to tackle.

For the background, I am a graduate in Computer Science with 3+ years of professional experience in software development.
I found the course to be challenging enough, and equally rewarding. The swirl exercises are good and help you practice the commands in a guided setting. The programming assignments were very challenging. I ended up working on them for 7-8 hours on average. Assignments were designed to make you investigate and study on your own (this really helped in my understanding of R).
Surely, I would recommend R Programming. However, novices in programming will have to invest a lot of time and effort on their own to navigate through the content for significant gain.

The course is interesting and very engaging. However, I felt difficulty in writing the codes for the assignments since I don't have a coding or programming background.
por Sebastian D•
level of difficulty for quiz and assignments are sky high;
it seems in the course you learn how to multiply and in test you are asked to know how differentiation wordks
por Yuri C L•
It is a good course with very challenging assignments. Given the class levels, maybe too challenging. Though I must say I did complete the course before its deadline.
por Sagar D•
Course is really great. However for the absolute beginners it might be challenging as the assignments and videos assume basic knowledge of stats and programing
por Ong W J•
This course is tough if you have zero background in programming. I struggled alots especially in the last assignment.
por Xavier A•
Good course but in my opinion very difficult to achieve if you don't have previous programming knowledge.

Homework and programming assignments are not related with videos.

Nice, but limited explanation for beginners.

In short, I learned a lot in this cocurse but I would not consider it for beginners with little programming experience. I spent at least 3-5 times more doing the assingtments. The information presented was very valuable but the pedagogical part was not well done. The chunks of information were poorly connected between themselves, making the learning process tidous and hard to achieve. The visuals were very sloppy with only white slides and a font too small. For these reason the lectures were boring and unappealing. My suggestion is to take more care of the didactic aspect of the course. Many times I had to watch YouTube videos on the same topic that I had just seen, and I can say that a colored diagram made all the difference between understanding everything and not understanding nothing at all.

For this second course installment of the Data Science Specialisation, there is an immense gap between the lectures and the assignments. I completely understand not being "spoon fed", which is a critical aspect of learning anything on your own. However, the jump in expectations between Programming Assignment 2 and Assignment 3 was incomprehensible. You could work your way through #2 but with #3, it felt as though you had a plethora of information thrown at your way, adding to the confusion, which you then had to stare at for what felt like "light years" to fully decode, in order to get through the quiz.
por Alejandro M•
The course is too ambitious and some themes are explained in a very plain and boring way. I can't say you will learn nothing, the course isn't too bad, but if you have no prior experience with programming o even if you have but not in R, the course programming assignments will be a little difficult and the material. If you want to complete this course you will have to invest a lot of time searching for things and/or waiting for help in the forums. 5/10

I learned a lot from this course. My only concern is that, most of the assignments did not match with what was discussed in the lectures. It became difficult for beginners like myself to catch up. It seemed that the lectures were incomplete. I hope this gap between lectures and assignments will be addressed soon. Nevertheless, I learned a lot from this course and now I can say I know something about R programming. Thanks Coursera.

Difficult to follow and course curriculum not fully in line with the quiz. This course could easily span 6 weeks to avoid information overload and unnecessary time pressure while working full time and with family responsibilities. Optional SWIRL exercises should be revisited between Course 2 and Course 3 as there's very little time within each week.
por Elisa R M A•
The assignments are too difficult. The instructors gave a very basic overview of the subject only to throw really complex tasks for the students. ALL the assignments required me to spend HOURS on them, looking for help outside what was given in the course, it was frustrating. I learned a lot, but I would learn a lot more with proper instructions
por Suwei W•
I learned something, of course, in this course. But without previous experience in data science, I found it OK to understand the lectures, but always got lost in the coding assignments. I tried to finish it on my own, but it turns out I have to search everything online. I felt that there's a big gap between lectures and assignments.
por Andrea C P•
For me as non programmer, the course resulted sometime hard to follow. Simply adding a pointer when Prof. Peng is showing a slide it would improve the understanding.
por Ana L d S P•
This course was not what I've expected. The functions lessons were not achieved, because it was not teached well.
por El M•
very good course but you need much more time then announced to finish the assignments
Tutorials are indispensible for students to complete the assignments.
por Ramesh B•
This course is for programmers.
por Sherif A•
Needs to be more interactive
por SANJAY K V•
I believe many of the students taking this course might not have any prior coding experience. Personally, I found the assignments quite challenging (rather than intellectually stimulating or providing learning) as many of the issues and syntax used in the assignments were never elaborated in depth in the videos. There may be a few people with really good statistical and coding background, who may not find this review much helpful, But, being new to coding, I can understand this and I believe the people who really need this course to equip themselves with these lessons may not be adept at solving some of the problems asked in the assignments. Please take this constructive feedback into consideration while modifying this course (if you do so). Otherwise, it was a wonderful course and gave same basics to build a foundation in R. Thank you.

Swirl is an amazing learning tool and it was the best of the course. However, unfortunately the course videos and supporting material does not help too much in order to complete the Programming Assignments, specially the videos. There is a huge distance from what has been teached or maybe how it has been teached to what was asked to do during assignments. Nothing against to a good task, but would be fair to provide a proper knoledge (e. g. including examples at same level of the assignments, maybe something step-by-step) so we could complete them without spending so many hours looking for other sources which provide what maybe some of us were expecting to find right here.
The course was somehow frustrating and disapointing on this matter and I don't feel confortable in recommending it.
