The course was fantastic and learned the things which I could not study from many books I had referred. I have spread this message to many of my friends and colleges. Thank you very much.

Some of the earlier quiz questions seemed impossible to answer based on the lecture videos and materials, but otherwise this was a generally informative and engaging course.

Good enough for a free course offering very basic understanding of the topic. Lots of video errors, and sometimes the lecturer's speech isn't very smooth. Tests are poorly worded sometimes in ways that contradict the language used in the lectures, making them difficult to pass even with notes. I wouldn't pay for the certificate - if I were an employer I would not recognize this course as teaching any sort of proficiency.

The content was really neat and definitely not something I had been exposed to before. I really liked the quantitative parts of the course and wish there had been more time spent on that and more quiz questions on that.

The reason I am ranking this 2 stars is that I felt the quizzes were unreasonably difficult (or perhaps they had bugs). Week 2 quiz I had to take multiple times and really couldn't figure out what the correct answer was. Looking at the discussion boards I believe my sentiment is shared. I have taken multiple coursera classes (Astronomy, Astrobiology, Calculus) and these are by far the most difficult quizes I have encountered.

One of the best classes I've taken. It was difficult for me. I had to take the quizzes many times usually to get an A. Worth the effort. I completed the class. I'm proud of the accomplishment.

There is room for improvement, like showing quiz answers once submitted and editing all of the transcript errors but the information and additional materials are great resources for people interested in getting started with in the field of epidemiology.

I enjoyed taking this course, although I felt the quizzes at the end of each week were much harder than the practice questions throughout the videos requiring me to go back frequently. I do feel I have learned a lot I can use moving forward.

Great overview of scientific methods of epidemiological studies. I would have loved more advanced material to be available, and maybe discussion questions to guide the forums.

I enjoyed hearing about epidemiology, but didn't find the quizzes very useful. I was expecting more practice doing computation or examining case studies. The lectures also had no time in between slides to pause, write notes, and make sure I understood what was just said. I liked that the lectures were well organized and the review questions in between the topics of discussion.

The course and content are good and well taught by the teachers. However, the lessons are very short and the test complicated to be carried out, mainly for not accepting the partial note of the questions that have more than one correct alternative.

I am a little disapointed with this course. I have completed the third week, but quizes are too big, and the questions are almost impossible to compare with the lectures.

It seems like what is evaluated is your ability of getting languages nuances, and not the epidemiology subject.

There is no real flow between videos and questions, not easy to follow. Good efford, good content, just wrong methodology for online training for 2015.

Great course!!!

I learn a lot of new things and reformulate many misunderstood concepts.

This is a very informative and concise course for the

Extremely beneficial. Professional and detailed.

so informational and very important

Good !

Good basic intro to epidemiologic terms and very basic calculations.

love it.

This course is a good starting point foI

Très intéressant et très bonne pédagogie

Muy interesante y una genial herramienta para sumergirte en la Salud Pública. ¡Excelent!

I enjoyed the presentation of the course; course material simplifies complex concepts which makes learning interesting. I look forward to joining another MOOC from UNC.
