Great Beginner Course. There are some parts where there will be frustration, but the forums are helpful. Any type of class involving math and science involves practice and work. Professor is great!

hemistry is the study of matter and energy and the interaction between them. There are many reasons to study chemistry, even if you aren't pursuing a career in science.

Chemistry is everywhere in the world around you! It's in the food you eat, clothes you wear, water you drink, medicines, air, cleaners... you name it

It was a very good course, and I enjoyed it. It was fun, and I think I learnt quite a lot.

When I entered this course, I wanted to expand my knowledge on the foundations of Chemistry. This course helped me to do that and much more. Through this course, I was challenged enough that I can confidently walk into a Chemistry classroom and ace the pretest. I recommend this for anyone who is trying to get a degree in anything branched off of Chemistry.

Excellent course. Although, it was very challenging to me to complete it and I had to repeat some of the videos, I am very happy that I decided to take it. It helped me to repeat my knowledge.

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.

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! :)

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!

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 :)

I would give the course 4.5 stars if I could. The course is a great introduction into Chemistry and I really enjoyed it. Professor explains non-trivial topics in lovely and easy to digest way during first 4 weeks. However, the course shifts gears in weeks 5 and 6 and I had to watch lectures twice to fully understand concepts. Moreover, to solve advanced problem set for week 6, I had to read about Ksp calculation outside. Apart from this inconvenience, the course and professor are great.

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.
