It's a highly educational and deep course, but it was difficult. I believe the course is from 2013, and all of the tests demand facts and information. Others of them were not available at the time, and some of the URLs provided were not functional, so searching for information was a challenging process.

Great introduction to sustainable development. Materials are easy to understand and engaging through the series of videos and quiz. Some links in the quiz are not working, but it's a minor point. Overall, I learnt a great deal & inspired me in my next job that has a focus on sustainable development.

Espectacular el curso, muy buenos temas. Metodología simple, pero atractiva, que permitía estar concentrado por las preguntas que estaban en la mitad y los controles que en la mayoría de las preguntas eran de aplicación, que permitían buscar nuevas fuentes de información, útiles para usos futuros.

Excellent course, everyone must understand what is the issues in the plant and take a action for a better future to the our and next generations, is important to know what was the first and whats is happening now with our environment, our food and other goods than allow us to have a quality life.

a horrible perishing, SD MUST BE ACHIEVED! The knowledge gained out of this course is by far beyond "a mere awareness on SD". The course ought to be part of a curricula and further enriched to yield a degree, thus opening up more perspectives for life and career development. BIEN JOUE, PROFESSOR!

This is a very complete course if you are interested to learn about Sustainable Development from the beginning. You will start understanding why the economy, society and environment, always joined to a good government of our countries; are the key to reach the balance of our civilization future.

I really enjoyed learning new topics, and then with the quality of tremendous teacher! For me, it was a challenge every exam, because it requires a lot of preparation; I received it from both the videos and the super demanding exams. This was an online course that is worth passing. Thank you!!!

Great refresher course to get more up to date on the significant challenges facing sustainable development and to learn about practical responses required to address these challenges. It was great to hear Prof Sachs' first hand experiences supporting the UN MDG journey and now the SDG journey.

I loved the course!! The topics were diverse but still very related! It has helped me to understand sustainable development as a complex, multidimensional concept. I would like to emphasise the passion and knowledge dr. Sachs shows for the topic! He is a real role model for me professionally!

Very impressive course, the lectures and assignments are very well organized and are quite interesting.

It is very important topic for everybody in today's world.

I hope a lot of people are encouraged to take this course, so everybody can start contributing to changing our world for the better.

An in-depth understanding of sustainable development exceptionally taught by Mr. Sachs covering many dimensions on the topic. This course has certainly led a foundation or cultivate within me a basic understanding at the least on sustainability which will help me out with my Master's program

this course is the most important study that i have dune in my life

it is really compelling every one in this planet must take this course

thank you JEFFRY D SACHS you are my hero, you are really the greatest economist in the 21 century.

why you haven't been the president of the USA yet !!

I love the course very much because I gained a more well-rounded understanding about Sustainable Development rather than just being skeptical about why the world works this way or that way. Current problems are indeed complex, and this Prof. Jeff Sachs explained it thoroughly from A to Z.

Curso interesante para conocer el marco económico, social y medioambiental global. Si bien es bastante general en los temas tratados, permite tener una visión sistemática de los hechos que han guiado al concepto de desarrollo sustentable y presenta ciertas directrices para poder lograrlo.

Prof. Jeffrey Sachs was one of the best speakers I have attended classes with. He spoke very clearly, and the course is very comprehensive. I would love to attend other courses that he will teach in the future. Thank you, Prof. Sachs for imparting your knowledge and experiences to us.

Great course. Enjoyed the content and the professor was enjoyable to listen to. Only issue I encountered was outdated links in the quiz/ exam questions. Some of the links don't work at all any more, and some don't match the description of how to find the data the question is asking for.

Great course. An amazing eye opener. I learned way much more than i expected. And i have become a fan and follower of Dr. Sachs - impressive capacity of teaching by telling 'stories' and to keep you all the time interested , connected, motivated and wanting for more and more sessions.

The beginning is not always easy but if you are committed to achieving your goals, you will do everything it takes to succeed. I am glad I didn't give up and was able to beat the deadline with victory. Thank you Professor Sachs for the great lectures. Thank you UNDP for sponsoring me.

This was such a valuable course. Dr. Sachs presents a compelling case for sustainable development in a factual, compelling, and understandable way. I recommend this course to anyone who wants to better understand the complexities of sustainable development and how we can achieve it.

Awesome course. Jeffrey Sachs' understanding and eloquence to decipher and explain the new challenges arising from the unprecedented occurring and upcoming changes is just ineffable.

Recommended to anyone wanting to know more about this new approaching era of sustainable development

Began the course to search for a source of hope. Instead I learned of the dire situation that we are in and the urgent need that we change our course of action NOW. As the professor mentioned, we have a path moving forward, now we need to get to work and change business as usual.

The course itself is really really good, Professor Sachs is knowledgeable and makes every lesson interesting and easy to understand. However, I think the tests need improving, as many links are broken or outdated, I found that a bit frustrating. All in all, it's worth following.

An exceptional course with extensive amount of information about sustainable development very nicely presented by Prof. Sachs and a lot of support material. Recommend it very strongly to anyone who is interested in sustainable development. It changes your view on every thing!

I really loved this course. The best so far. Professor Sachs is fantastic. The only issue I found was that in some quizzes, the link to the questions wouldn't work and it was hard to get it the right answer. Thanks for the opportunity of doing this incredible online course.

Very informative and comprehensive course - a combination of AP Human Geography, AP Macroeconomics, AP Environmental Science, and more! I enjoyed the lectures and the quizzes (exploring cool websites is full of fun). Lots of thanks to the professor and Columbia University!
