Before you can run, you must learn to walk.\n\nKasper's well paced tutorials will give you confidence using the tools you need for genomic study.

Excellent introduction to Bioconductor. Thanks to the team. However, absence of inputs from TA or Instructor was felt in the discussion.

Very frustrating and disappointing experience. The lectures were hard to follow on many levels:

1) The enunciation was unclear and subtitles were often of-the-point, plus they covered-up the code lines that were being discussed.

2) The lecturer often failed to explain logical constructs that were being used, despite the fact that the course should have been understandable with no R cran/Bioconductor experience.

3) The method arguments were either not explained, or very vaguely mentioned, which means applying them to new situations was unnecessarily complicated.

4) No feedback at all was offered from course organisers/reps to anyone, even after complains in discussion forum about quiz questions.

5) No feedback for solving the questions/correct answers even after the deadline.

6) Quiz questions required methods and logical constructs that were not explained/used/mentioned in the lectures. One quiz lacked background information of what data needed to be used (the info was available in the previous version of the course). Some quiz questions were biologically inaccurate i.e. confusing genes/transcripts/exons.

Great subject, yet a very difficult field to teach, and unfortunately, this course doesn't do it well enough.

The course is sloppy compared to all the other great courses on the Genomic Data Science Specialization.

Since Use of R and Bioconductor can be tricky, it would be nice if better examples were much more elaborated.

The Quizzes have a lot of questions, which are too difficult to answers, generally because the revolve around using 10% of the introduced material to do 90% unexplained analysis. You would need a lot prior knowledge to Bioconductor packages, to be able to answer and even sometimes understand many of the given questions.

Quite a shame!

Lectures are poorly understandable and the code examples are not explained in their meaning. Also some questions of the final quizes are difficult to understand. All the lectures and the quizes should have be constructed on a simpler use case

The course is outdated. There are no active discussions, no help at all in the forum. There are no mentors available which makes it difficult if you are a beginner. Not worth the money, this course should be free.

I struggled so hard! No way near the same level as the other courses.

Came from Computer science background and felt that I missed so many terms and concepts that were required for this course

The course is hard and needs previous knowledge of R. The time for for doing the "quizes" are not long. On the other hand, the questions resemble real world bioinformatics problems. The real inconvenience with this course is that the Forum does not work. Because not all that is questioned in the "quizes" are thought in the classes. So a help from the Forum is a real need for this course to work smoothly.

Lots of good data. Really a walk through of coding without too much theory. Would prefer a little more theory. Would have helped in completing the course and capstone. Ended up having to take Eric Lander Intro to Bio course on edx to really understand what I had done. In particular, a better explanation of what is going on at a basic with methylation marks and how the Epigenome Map was constructed.

Lots of knowledge but not systematic. Hard to follow for R beginners and there should have been quiz in lectures (like the "Algorithm for DNA sequencing" course). A lot of knowledge used in the homework was not mentioned/addressed in the lectures.

Discussions in this course are voiceless and dead and the instructor never appears in discussions. I couldn't understand anything from video lectures: cannot understand enunciation not enough detailed, lack of examples related to the assignments. So the only source was repository http://kasperdanielhansen.github.io/genbioconductor/ with html files. And a lot of searching through bioconductor forums.

I liked the relevance of quiz questions to real life genomic questions, but all quiz questions were outstandingly difficult, because of both lack of examples in lectures and errors in some packages inside bioconductor.

Overall I expected much more from this course and I cannot recommend it to anyone.

Confusing, not straight forward, transcription is all wrong.

the class gave me nothing. nobody wan's to waste tons of hours to learn nothing. so I personally think this course is on of the worst classes among the Coursera.

So practical! I learned a lot about specific and useful cases. It is true that I have to learn a lot yet but with this background, I will get used to any code soon.

Amazing course, motivated me to use bio conductor for descriptive seq studies of DNA.

The content is relevant and presented well, though slightly out of date. It would be very helpful to update this course. Note that the discussion forums haven't been tended for years so they are not at all helpful and some code is deprecated without warning.

Great Introductory course for sequence analyses using Bioconductor. However, the quizzes badly require more explanation. An update to the course to introduce currently more relevant packages and analysis methods would add more value.

Interesting course! Unfortunately little explanation on why we are doing the analysis steps from a biological perspective. Some quiz answers seem outdated. Additionally the lecturers don't seem to react on the forum. Messages in the forum are pretty old as well, the course seems to be abandoned.

Course is not good at all. The instructor assumes that you have a good genomic background.

While this is a very challenging class, its worth it! Imagine learning about a database and query language designed specifically for dealing with genomes!

You will need to know R very well, and Bioconductor. At the heart of this class are the quizzes and solving the problems there is a real challenge.

There are ample materials, in the form of slides, videos and code, as well as a textbook whose chapters are in the instructors archives and also available in pdf form on the Internet.

Key to understanding the material is knowledge of the structure of the Genome, DNA and RNA. Knowledge of transcripts, Exons, Introns, and other data structures is assumed. A bibliography of papers and references would have been helpful. Like all classes in this specialization, do not be shy about seeking help --Google, Wikipedia, and YouTube are your friends.

This software is used frequently in the real world and is worth your time to learn it.
