Many of the links in the quizzes after the videos are expired, it would be helpful to make the quizzes with new links to new data to explore. Furthermore, there could be more controversion about solutions. It seems as if there are many easy solutions and that Professor Jeffrey Sachs knows them all, but the real world is often more complex than that and there are different opinions in the scientific community.

A lot of the information was a bit out of date and most of the discussion forums have not been updated in a couple years and are not monitored for recent posts. Also on the quizzes there were frequent issues where the correct answer could never be found even if you choose one option every time you take it. It was an interesting course but could definitely use updating.

The course is excellent, I'd love the way the professor explain in detail each topic. However, some data are out-of -date and some links in the quizs are broken. moreover, some questions are wrong because of the data used. Finally, It is a shame that after dedicate 15 weeks in this course, coursera or UNDP don't give us a diploma or certificate of completion.

I learned a lot and the course was exciting. However I was disappointed to find out that after 13 weeks of studying there is no certificate, Yup, you have nothing to show for. Some of the links used in quizzes do not work, i.e. one could lose points. While the course is very good, it seems no one bothered to verify or update

Sachs is doing valuable work and I like the premise of the course very much. The videos seemed to present a lot of painfully obvious information, however, and I'm afraid they were not terribly engaging. Maybe just too much/too long? A shorter version of the course that digs in a little deeper somehow might be more alluring.

It gives a well based numeric approach to sustainable development, but fails to approach some subjects from an ethical point of view. At some time, Prof. Sachs points out a few numeric indicators that favor economic development, but when talking about reaching these numbers, he offers more than debatable ways.

Many of the links didn't work, thus it was difficult to find the sources to fulfill the test requirements. If I would have known that the course material is over 10 years old, I would have not opted for this course. Prof. Sachs' knowledge and enthusiasm is wonderful. Many thanks to him for sharing this.

The material is of great importance. My notes are: the length of the videos is relatively long and I found it a little bit difficult to focus all the time through the video. Secondly, the course material is not updated, there are missing link pages in some quizzes. However, the course overall is good.

The course content is interesting to learn and substantial. However the "assignments" or "quizzes" are not updated and asks for information from links that no longer exist. Some of the information is dated, but overall, provides a through foundation for someone interested in sustainable development.

Content is great, but the course needs some major updating. Lots of problems with quizzes and broken links or information that has changed over time (there's a lot of help from mentors and other students regarding this, but it's still a problem). Also, the course does not offer a certificate.

A bit out of date, should be updated with the adopted SDGsA bit prescriptive, could include more debates and perspectives, for example the solutions presented regarding food systems could include discussions about reducing meat consumption and increasing plant based protein production etc

Professor was quite knowledgeable, and covered a breadth of topics. However, he often presented his political opinion as scientific fact. The quizzes/tests were also based on regurgitation of data/knowledge, rather than higher-order thinking such as application or synthesis

The course is really interesting and covers all basic topics in sustainable development. However the course material and data is outdated from 5 years ago. As sustainability is crucial and changing so fast these days, important discussions are missing.

Course content, especially the maps and data referred to in the tests are outdated. Otherwise, this is an excellent course for anyone to understand the theory behind sustainable development and the major global issues associated with achieving it.

started quite good, but slow videos and the last quiz was about just numbers. it is good to know what are the measurements, but if we won't teach about that too, the more concrete informations and not numbers would be more informative and useful.

Información de suma importancia para el aprendizaje, recomendaría traducir las pruebas y sub titular las presentaciones; des afortunadamente solo algunos de los vídeos cuentan con sub títulos en español.

Great content wise but many source links are outdated and websites have changed! Especially for quizzes and the final exam some sources were thus not adequately available. Recommend updating these :)

Very informative course and gives context to some concepts that I had previous shallow knowledge on. Alot of the links failed. It's a great course but needs a lot of updates to stay relevant.

This course not updated and leaves out a lot of developments from 2020. Overall good course to get a general idea of what SD is. Like, let's talk about SDGs and less of MDGs ?

Excellent content and lecturer, however the links are in bad need of an audit as they effect the outcome of exams as they are either out of date or no longer work.

loved the professor but most of the links on the quizzes are outdated and the forums are often not helpful. needs to be updated completely

Hi, I loved this course. However I'm a bit surprised that didn't got a certificate for doing it. That's why I didn't put 5 stars.

Some of the links are no longer functioning and thus, gaining access to exact information for the past (2013) is not possible.

If this course there still be on coursera why there isn't certificate.

It is unbelievable that you don't have certificate.

The course is too long. Videos are also too long and are not so interactive so students could get bored.
