Overall a great course I loved it. Some of the links need to be updated as some websites and pages don't exist anymore, and I got some questions wrong that were very clearly correct. Apart from the few bugs a very informative course, Professor Sachs is a wonderful speaker.

I'd like to thank Professor Sachs for this unique and inspiring course. It has increased my interest in sustainability and market economics by two folds. This course was to gripping that I completed it in just 3 weeks. Thanks again Professor Sachs and Columbia University.

Very useful, professional and holistic course. Thanks a lot to Professor Sachs, to the University of Columbia and to Coursera for making this great course available to everyone. Raising awareness about the importance of sustainability starts by sharing valuable knowledge.

Excellent material for today that determines the future! It engages one to think, act & move now for the love of our children and this planet! Truly, Prof. Sachs is one of the great prophets of today that reminds us what of what was spoken by great men 5,000 years ago!

I found this course really useful and I recommend it for all the students or people that are interested about International Development, Sustainability, Problem solving solutions, or like the professor said, for the dreamers that hope that a better world can be possible.

Excellent course. Unfortunately, Coursera does little to maintain the material, leaving the Mentors to correct obsolete data for the quizzes. Professor Sachs has presented excellent material. It's up to Coursera to keep the material up to date when they are informed.

Excellent! You get to know a bit of history, therefore you can learn about the evolution of the concepts and why we have the ideas of today's sustainable development. It also gives you a wide range of what do we need for sustainability and what is being done. Very good!

Great view over the big challenges of today and the future.

Excellent explaint and a lot of information about the history and the reasons of our problems on planet earth...

Gives you a profound knowledge how we should manage the future to have a better life for everyone.

An excellent, informative, and interesting course. The course could improve by updating the datasets required to complete assignments -- several websites no longer display the data necessary to answer exam questions. The course content is excellent and well-presented.

I loved the material and topics of the course, I think everybody shpuld take this course to understand the moment we are living in and the possible solutions to make this a better world. I just suggest to uptade the exam website links, since some of them are broken.

Really enjoyed the course. Opened my eyes to more elements of sustainable development that I was not aware of previously. Fantastic Professor, with excellent, relevant examples. Makes me want to find a job in a sector that supports the MDGs or SDGs. Inspirational.

Very interesting course, very well presented by Prof. Sachs. This course focuses on every field of sustainable development at the global scale with an international approach. Prof. Sachs' point of view as a UN advisor is extremly instructive. Thank you Prof Sachs!

This course provides you the basics of Sustainable Development, framed around economic development, environmental development and social development. Prof. Sachs is a fantastic instructor and the materials provided are very helpful to learn more about the subject.

It was an incredible privilege to be taught by Prof Sachs, during this course. The content challenged some of the current views I held about sustainable development and encouraged my own thinking on the subject matter within my skill set. Highly recommendable!!

I really enjoyed the course and learnt a lot. there are a few links in the quizzes that don't work properly or are out of date so I found it difficult to answer some of the questions correctly however I completed and passed the course and found it very well done.

What a great course to pave the way towards my master's degree in sustainable development. Thank you Professor Jeffrey for sharing your valuable knowledge and thanks to Coursera for being the channel, what an astounding way to revolutionize the educational model.

Professor Sachs is excellent, transmitting the contents with clarity and porpoise. The course topics are broad and inter-connected. I do recommend this course for people who want to start to have a deep understanding of what sustainable developing really means.

Very interesting course. I learned a lot and inspired me to continue studying about sustainable development.

Easy to follow and understand, the quizzes and exams were very dynamic, so you understand and go beyond the lectures and research more about the topics.

Great course taught by Professor Sachs, who genuinely seems like he wants to make a change!

The only gripe I have with the course is that some of the links in the tests are not working since the course is a few years old. Would be great if those were updated.

Great course that highlights the need to take action to save our planet so we can continue to prosper and thrive. For that, a lot of things need to change. Dr. Jeffrey D. Sachs points out where the challenges are and helps us form ideas to shape a new future.

This set of videos really gives you a complete view of what sustainability must deal with and I really liked the type of tests used as they are not about how much you can memorize, but how able you are to analize. It tooked me a while, but I really liked it.

Full of the diverse sub topics about sustainable development the course is pretty good in motivating you to consider this astounding subject that sadly requires a let's say continuation to allow you to make every thing that is discussed part of your life.

One of the rare courses where I managed to go through until the end and passed! Detailed and comprehensive, but still very easy to understand explanation by Prof. Sachs. I definitely recommend this course for anyone interested in the future of our world.

Dr. Sachs is a very engaging professor and the topics discussed are very interesting. If you are into sustainability, this is the "I must have" course. I enjoyed every bit of it, and it lead me to search for Dr. Sachs books and read them. Just awesome!!!

One of the most brilliant courses that I have undertaken twice so far.. and mentor! Hats off to Professor Sachs, with what simplicity are such complex issues covered... holistically, and with passion. I shall return to it again to refresh the memory..
