Thank you Professor Dorian A. Canelas! It made me much more easier to understand the basic principles of chemistry and it builds me a lot of confidence in answering some of the problems in chemistry.

It is a wonderful course for Middle school students. A first course in Chemistry, for the gifted students who will do AP Chemistry. Not suitable for adult learners who need an advanced introduction.

On the whole this course was worth my time. I had never taken a chemistry class and I was looking for a course to prepare me for other science courses that required a background in basic chemistry. I found the course very easy and quick. All concepts were well explained, except those in week 6, where a plethora of new and basically unexplained notation (Lewis Dot models, chemical structure diagrams) made the lectures harder to follow. I expect that I will learn more about that notation in the second course.

It was a wonderful experience. All lectures were excellent. Simple and clear kind of lecturing it was very easy and interesting to follow. Sometimes i feel sad if my phone shows low battery power during the class time. I hope i could attend almost week exercises well. Demonstrations also very helpful. I spent time for getting better mark by repeating exams when ever my percentage become low. Special thanks to Prof. Dorian Canelas.

Quality course. Very basic in material but fabulous to understand nomenclature and other technical necessities. I used it to prepare for a honors chemistry course I am taking in my sophomore year of high school. It, in my opinion, is perfect for that use.

helpful course, but advanced problem sets are sometimes much more difficult than concepts shown in video sessions

Clear explanations and an excellent course for beginners. Very slow to begin, but informative and thorough.

There were some errors in the video playback, one entire lesson near the end seemed like it was skipped.

I wish more time was spent going over the mathematical equations and more examples were given.
