This was a lot of work and rewarding to complete. The final project was challenging and the forum contributors helped a lot in pointing out good resources or strategies they had used.

Great Course if you are interested in dissecting the genome. Galaxy opens up this invisible world and allows even us little people to explore the world once reserved to only Academia.

Course was good. But at times running jobs in Galaxy was difficult due to their internal issue and the discussion forum was not very helpful to guide.

Most of the content is outdated and there wasn't much help in the lectures for tee final project. I had to search for my own resources to complete.

Course materials were good, final project was very difficult without prior experience. Lots of digging through forums to find details.

The final project is the real challenge, the course lectures are just and introduction and you learn the hard way with the project.

Quite a few assumptions of knowledge for the learner making it difficult for a beginner to understand

The videos were not enough for me to complete the project course in the expected time.

I am taking this course as a requirement for the Data Science Specialization. I appreciated the concept of learning a platform in which I could conduct bioinformatics, but I feel the course did not provide adequate guidance and information. The lectures were basically video workshops with a few gems of knowledge here and there. I am now at the end of the course but I feel like I learned nothing but a few steps to running an analysis or two ( which I could have done for free through the Galaxy website itself). More significantly, its not wholly clear to me why some of the processes were conducted, or what, explicitly, could be gleaned from the analyses. My expectations were that the lectures would be more in depth about the science behind the tools available, why you would use such tools, and when to use such tools. I think this course would have been perfect as primarily an intellectual course with a hands-on introduction towards the end.

This course made me confused all the time. There was a great leap between the first introductory course and the second (current) one in this genomic data science specialization. The first course seemed designed for beginners, while the second one requires a decent amount of background knowledge about possibly programming and other data analysis technologies. However, information such that is unclear on the mainpage of this specialization; as it says, "Some related experience required." Also, the final project was somewhat so irrelevant from the course lecture that a great deal of self study was required, which was another great leap of difficulty in this course. I think that such challenge and difficulty would actually be acceptable if the students could be announced beforehand, before the project started or even before we got enrolled in this course so that we would evaluate the difficulty and be mentally prepared for the project.

The course Info was too simple. While the explanation of Why Galaxy and what the idea behind it was great, the content taught by the videos was more than basic. All this I have learned by trial and error myself, and I completely missed the info of WHY using THIS tool and not others. About extra options we did not talk at all.

Additionally, after all these easy lectures and quizzes we were left with the final assignment that was super-hard. The vidoes only prepared for 1/3 of the workflow asked for, and for the rest one was left alone with a tool that was suboptimally introduced. Furthermore, the galaxy instance was crashing regularly, making the convenient batch tool impossible to use.

While I liked the idea of grading each other, it was too much work, as everybody got different answers, because of too hard questions. Therefore I spent quite some time on grading, which I did not expect

I found this course to include very little informative teaching. I felt like there was a lot of information that could have been explained, but wasn't. Even the lectures associated with learning Galaxy, was more an exercise in clicking things, than understanding what the goals were. I also don't like how there were lectures associated with setting up a personal instance and using AWS, when neither was a good/viable option, and neither was necessary for this class. Finally, I do not feel we got enough direction to do really much of anything on our own, without significant self-learning. I wasn't given even enough tools to understand remotely how to handle the final. I feel like if I wanted to just learn it all by myself, then I wouldn't have signed up for a course.

I have very mixed feelings after completing this course. I can hardly say I feel I have learned any valuable stuff, especially in contrast to the first course when I had a feeling "I am growing with knowledge".

Here, I was able to follow lectures' instructions but I did not fully understand why I was doing this and that. I believe not enough foundation was given to make people use the Galaxy tools consciously. The final project was ridiculously far more difficult than what had been covered in the class. I truly believe in the idea of giving ambitious final projects, but I do not believe in the idea of giving the project that is by no means doable based on the course content. Very discouraging.

I think this course might have been great if I did it like 5th or 6th in the certificate sequence. I think this course assumes you have a lot of knowledge about both biology and statistics that I do not have, nor will anyone else who has only taken the first intro course. Even after having submitted my final assignment and peer reviewing others, it is not clear whether or not I or any of my classmates used the correct methods to complete the assignment. A valid solution to the final project hasn't even been given to us as part of the course, so I'll never know whether or not I did it correctly.

The course itself was not bad. I did learn a good bit about some of the tools in Galaxy. The project was a complete disaster. Very little of what was actually taught in the course was applicable to the project. I ended up putting in over 5-6 hours on just the project. The whole reason for taking a course is so that someone can teach me things and I can learn them. If I knew I would just be spending all my time self-learning, I'd save myself the money and just do it myself. Very poorly designed. I gave it a 2 star rating only because the actual course lectures were decent.

I was disappointed by this course. The course seemed to assume one already knew a great deal about genomics and simply wanted to learn to use the Galaxy platform. As the second (of 7) course in the "Genomics Data Science" sequence, I had expected to learn more about genomic analysis. The course felt like publicity for the Galaxy platform, and was generally uninteresting. Experiments were run, but the input data and output results were hardly discussed. Some of the examples didn't run. I did not complete the course.

Classes and quizzes are good. Final project is AWFUL (there is no lecture teaching about variant calling tools on Galaxy and how to manipulate VCF files and THAT`S what they pick for a final project!). Learners are left alone and lost to complete it. You have to dig through the discussion forum to get some kind of hint of where to start. The peer review system is also not a great way to do it, since as I mentioned the reviewers themselves (learners) are lost on the subject, so how can they even review something?

I am very dissatisfied with how there was absolutely no outside help/feedback from instructors or mentors in the forums when clearly the final project was outside the scope of the material presented. In the future it would helpful if either the lectures were modified to be more helpful in completion of the final project or the final project to be reflected of material in the lectures. Either way I felt like I taught myself all of this material using web resources and got absolutely nothing for what I paid for.

This course isn't kept up to date, no one from the course staff answers questions on the discussion forums (I see unanswered questions going back more than 6 months), and the lectures didn't sufficiently prepare most people for the course assignment. I have a reasonably strong molecular biology and coding background so it wasn't a problem for me, but I can see on the forums that a lot of people (especially those coming from a CS background rather than bio) are understandably very confused.

I felt like I didn't learn very much on this course. I think this course could have a lot of potential, but the course was very lacking in terms of explaining WHY things should be done. There was quite a bit of explanation of how to use the Galaxy platform, but there was very little explanation on why you should actually perform those tasks on the Galaxy platform. I felt like for the most part, I was just pushing buttons, without knowing why I should be pressing them.

End course work was too difficult. A lot of the technical details were not covered in the lectures which you needed for the exams and course work. In the end spent a lot longer than the estimated 2-3 hours for the course work, because of tedious Googling. I'd cover variants a lot more during the lectures and how to go from a RNA-seq data set to a variant caller and how to get the data from the info side of the columns. More detail please in the lectures!
