The content is good. The delivery of lectures can be more engaging, with aid of visuals to illustrate and emphasize important concepts.

El curso es muy bueno e informativo, no obstante algunos quiz tienen problemas porque los enlaces no abren o son preguntas ambiguas.

I've really enjoyed this course and I enjoyed following the lectures. I feel a need to do something real a sustainable world.

Very informative course however some graphs,data and reference sites mentioned there are outdated and need to be updated.

Course and content are great, but it would need some updates, the data used in the exams is often not available anymore.

Everything is Excellent. From quizzes to Lectures, everything is perfect. Just need the provision of course certificate.

Great course! Significant issues covered and well presented. Data errors in the quizzes make it less charming however.

Links to charts/graphs need to be renewed as some don't work any longer and makes it difficult to complete quizzes.

I learned so much. My only issue is that many of the links throughout the course no longer work or are not updated.

This course gave great insight into the subject of Sustainable Development and provided a fantastic starting point.

Some of the material is dated! Lots of developments have happened since SDGs, Glasow Conference 2022, Covid, etc,

Amazing course! The only detail to improve is reviewing links and datas that are too old or don't open anymore.

Thanks for this interesting class!! Lots of information & data! A very global view of sustainable development!

Excelente curso, mas exercícios muito defasados, o que atrapalha a resolução e avanço para p´roximos módulos.

A very interesting introduction to Sustainable Development and a nice journey led by professor Jeffrey Sachs

The lectures were excellent but the continuous assessments and final exam were very poorly put together.

Outstanding content, minus 1 star because some of the links are no longer working in some of the tests.

It is wonderful course. Whey the Columbia University offer a certificate it will be a Five star course.

Some websites that are viewed in quizzes are not found or deleted. I recommend to update the questions

Curso excelente, com muitas informacoes pertinentes. Contudo, material e exercicios estao defasados.

Very informative. Gave a real insight into the origins as well as present day sustainable development

Its very important to know what sustainable development is and knowing it makes a change in society.

Love it. Proff Sachs did not put me to sleep and that is a good thing!! Made me eager to learn.

The websites that are linked to some of the quiz questions are broken or doesn't exist anymore.

Very good, but after all the hard work one should be able to pursue a paid certificate at least
