It's been a wonderful experience and it has helped me review my preuniversitary knowledge of chemistry, while also adding some new information. Prof. Canelas explained concepts in a thorough and patient way, so that everything is understood. The tests were not very difficult, but they put me in the situation to make connections between different bits of knowledge and they also helped me exercise my arithmetic skills, as I was making a lot of mistakes through lack of attention. Thank you!

The course was extraordinary. Initially I was overwhelomed by the amount of videos each week had but after all they were perfect for ensuring that the concepts were understood. Professor Canelas is an incredible professor who clearly loves delivering this subject. I thoroughly enjoyed the videos, the homework and everything about this course. I hope she delivers more courses on coursera as I would love to enlist in them. Thank you for this course and for delivering it so masterfully :)

Excellent course! Great Prof. Canelas gave understandable, interesting and not boring lectures. I almost entirely forgot chemistry I learned in a high school and I didn't like it, but now I feel I know something and I got interest in discipline - chemistry is exciting)

There were couple minor mistakes in quizes (for example in one case the right answer was "aluminum sulfide" instead of "aluminium sulfide"), but they don't matter much.

I took this course to revise some skills I got at my chemistry class in high school over 10 years ago. Thanks to prof. Canelas I figured out that I'm not hopeless at all. I liked the way the course is structured, the topics following one another, the slides, the explanations, and of course little funny jokes - everything was perfect. I really appreciate the sense of humor of the lecturer. Thanks prof. Dorian Canelas and the team!

Prof Dorian A. Canelas is a wonderful teacher. Her lectures are very clear and informative and she does so in a kind, friendly, yet professional manner. I have learned so much in this course and sincerely appreciate what Duke University and Coursera have done to prepare it for us. The videos were just the right length and I found it super helpful that a transcript accompanied each video. Excellent course, I highly recommend it!

I have completed this course as of June 2024, and I am happy to say I am pleased with what I was provided with on this educational journey. The professor did an excellent job at elaborating on certain subjects during the videos, and the demonstrations stood out to me because it was easier to recall and remember information from them. I look forward to taking another chemistry course on Coursera with Duke University next summer!

I really enjoyed the way Prof. Canelas teaches. This course brushes up some parts of what I have studied in my high school chemistry. No words to thank coursera for providing such a wonderful platform for homemakers like me who want to remain in touch with their subject while staying at home. Looking forward to taking another part of this course Introduction to chemistry - Structures and Solutions with full enthusiasm.

Very useful course go get back into chemistry if you have not known it before or if it's been a while. For me, it was almost 30 years since my last chemistry study in school, and a lot has changed since that time! This is particulary useful, if you plan to study biology or you want to understand the basics in medicine, drug percription and it is a great pre-requisite to further study of different disciplines!

I love the course. Good and clear explanations. Week 5 could be challenging if you try to really understand and don't have a big picture / the general concepts in mind, but some questions would be solved at week 6 lectures. If you don't remember chemistry from school at all you may need extra reading or video lectures. In any case - a good place to start, worth taking! Thank you, Professor Dorian Canelas.

The Introduction to Chemistry Course has undoubtedly helped me grasp the fundamentals of the complex field of chemistry! I am already seeing the results of taking this course this summer as I have made quite an impression on my high school science teacher and peers. I would highly recommend this course to anyone who desires a strong base in chemistry (pun intended).

I found this course to be very helpful. It has helped me to learn a lot about chemistry and has really boosted my confidence around studying. Professor Canelas explains topics in a really effective way, making it easy to understand without having to constantly rewind the video to make sense of it.

10/10 highly recommend for anyone looking to get into chemistry!

It is a very helpful and Informative course. Well taught by Prof. Dorian A. Canelas . Thank you so much for the lectures which really helped me stand out in our class. I am class 10 student and understanding all these advanced concepts has really helped me a lot appreciate the beauty of chemistry in daily life. This course has enhanced my love for chemistry.

The course was very well presented and with a very limited knowledge of Chemistry I have been able to follow and complete it. The lectures were informative and easy to understand.

Thank you Professor Dorian Canelas who made the course interesting. I was not looking at achieving the Honours course but still enjoyed doing 2 out of the 3 Challenge problems.

I loved this course so much! It was super helpful, and I feel very prepared for my upcoming chemistry class at school. The instructor was great, and she seemed super nice and she made the course interesting. :) I recommend this course to anyone that wants an overview of chemistry, because I feel like this course did a great job at that. Thank you!

The best way to learn the basics of Chemistry. I studied this course prior to a general course as part of a Physics Degree and it was very helpful. Prof. Canelas' explanations are really easy to follow and gives you a great understanding of the subjects. Plus you won't need a lot of math to go around this course. Basic algebra should be enough.

Never passed a chemistry course until I took this one. Super helpful at building the foundation for future learning. Dr. Canelas explained important concepts in detail and refreshed them throughout the course. At times, the explanations were very fast which caused some confusion, but luckily you can re-watch videos on demand. Thank you!

a very helpful course for who wants to know the basic stuffs regarding Chemistry. However, this course involves some intermediate knowledge, requiring background before attending. Love the way professor Calenas names the compound using the example of the basket ball teams. I love her so much. Hope I'll have chances to learn from her again.

Very clear logic and easy to understand for beginners. This class will be very helpful for beginners to develop the basic understanding of chemistry definitions, terms and scientific reasoning. For students who have known the basic theory of chemistry, you can consider more difficult courses. I would recommend this course to my students.

The course is excellent; the in video excercises do help to reinforce the material. The weekly exercises are completely relevant to the lectures. Dr. Canelas explains clearly and with great presentations; she makes you feel at ease, but makes you stay focused on the lecture. Thanks for offering the course on an audit option, too.

Dorian Canelas is a fantastic teacher, and I like the way she teaches chemistry.

No hurry, step by step, very good lectures

I enjoyed a lot the lessons and the exercises

Dorian Canelas has the big power to explain in a very simple way the concepts and theories

and ask students to try calculations so to find the right ones!!!

Outstanding presentation! Its a very nice refresher/crash course for me. Its been years since I took my chemistry class, I am glad that I still remember the lectures. But nothing beat the actual face to face class, the in person can have more interaction and the posibility of having more samples on each lessons.

This course was very helpful. The professor is very knowledgeable and it is very fun to learn. The in-class demos and experiments were fun. It might be a little frustrating at some points during harder concepts. But all things aside you learn a lot in this course and it is not too fast paced.

I really enjoyed this course. The explanations were clear and concise and perfectly illustrated the presented concepts. I especially enjoyed the advanced problem sets which provided a deeper understanding of the material. Professor Canales is a talented and caring instructor. Thank you!

Excellent intro chemistry class. Dr. Canelas is very straightforward, clear, normal (all of the things that my science teachers in school weren't). A testament to the fact that with a good teacher, and the desire to learn, no subject is beyond your understanding.

Thank you Dr. Canelas!!!

Excellent. Very well articulated and explained, particularly the earlier weeks (acids and bases and redox reductions I found a little less thoroughly explained). Would definitely recommend to someone who was rusty on high school chemistry, or wanted to learn it for the first time.
