It's a great course! First of all, this course helped me understand and open my eyes to the world of chemistry through the concept of energy. This has helped me learn a lot. I've also gained a lot of stoichiometric skills as well.

I learned so much about Chemistry! I really did not understand it in high school since I had a first year teacher. But now I know so much. I'm going to buy the text the professor recommended at the beginning of the course.

I loved with all my heart the way Dr. Dorian teaches, it seemed to me that I learned things very quickly as if they were very simple. I learned a lot, I enjoyed and took advantage of it, very good rate for this course.

Dr. Canales, takes time to explain baffling calculations and that helped me pass my course. I'll recommend she review lecture on acid base and redox reaction, lecture note was too short with few examples to understand.

The course is both simple and informative. The instructor is very helpful in making us understand every small bits of information and she presented everything with examples which made me interested to this course.

The instructor was very clear and excellent explaining the material. I very munched enjoyed listening to her speak. I appreciated that she made suggestions on what to focus on for the exams. Thank you so much

The best explanations I've ever heard, everything felt so easy to understand. Also the humour of Ms. Dorian Canelas was really great and brought a very positive feeling when completing the course.

I find it very clearly presented and well organized. I really enjoyed it. Thank you! I liked it so much that I decided to translate it in my mother language so I can refresh the notions learned.

Excellent introduction. Engaging lectures, clear demonstrations and approachable problem sets. I love that everything for this course works from my phone. THANK YOU FOR OFFERING THIS COURSE!!!!!

I did not like chemistry because I had failed my previous chemistry 114 class in college. Taking this course have help me to understand the basics of chemistry. I'm grateful.

Thank You.

The course is great for refreshing and systematizing the key concepts from high school chemistry. Prof. Canelas was very engaging, and overall, it was just a very pleasant experience.

Enriched with knowledge .Thank you so much Prof Dorian. I have watched the again and again that you become so familiar . You are one of my favorite mentors . Your work is priceless.

An exceptional course to revise previous concepts. many a times strengthened my previously vague concepts. The interviews and especially the practical videos were very enlightening.

Got a far better understanding of basic chemistry almost 20 years after finishing high school. Many thanks to Prof. Dorian Canelas and to Duke University for creating this course.

I really enjoyed this course well,and I learned the basics of chemistry on reactions and ratios. Prof.Dorian.A Canelas thaught the topics in easiest and in understandable way.

To be honest, I knew a lot of the course (the program of the school course in my country provides for all this), but this course opened my eyes to many things in a new way

Excellent course!!! I enjoyed the historical background the lecturer used including the brief synopsis of the Chinese emperor consuming mercury pills to gain immortality.

It was a very interesting and pedagogically well prepared course, which made much fun. Thank you very much Prof. Dorian Canelas and all people, who worked on this course.

This course reinforced the basics of chemistry that I had already learned in Chemistry while also giving me to gain more in depth information from the teacher's videos.

great course, it gives me more knowledge in chemistry and also can maintain my previous knowledge in chemistry. I truly like the explanation in atomic interaction part.

A very good course to review basic college chemistry, or to prepare for for taking a college course if High School chemistry was taken too long ago. Highly recommended!

Strongly recommend this to people who lack backgrounds in chemistry or those who want to revisit knowledge they've not come across for a long time. I learnt a lot! :)

I really struggled with chemistry in high school, and this course is excellent! It helped me understand the core concepts of chemistry and I found it very enjoyable!

The instructor was great. The information was challenging, but clearly presented. The text used for this course was easy to understand for a beginner like myself.
