Overall, the course is a very good introductory course. There are many great theoretical exercises and real-life examples to their discussions. I also like how they simplified the mole concept into an easily digestible one. However, at times, the course gives examples that students that are not yet acquainted with chemistry may have a hard time processing. It also discusses some concepts that are tied to some chemistry concepts that the course decided not to dabble with, e.g., using examples to show Lewis electron-dot notation and electron pairs but not thoroughly discussing how that works. Because of this, I would not recommend this to students that don't have any idea about chemistry, or to those that hadn't learned it in their secondary schools.

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.

I took the course as a complete beginner. This was my first chemistry course and I enjoyed the professor and her teaching style. I believe this course is best suited for students who possess prior knowledge of chemistry concepts. I would definitely recommend this course to any one who is looking for a challenge. After successfully completely this course, I am very eager to enroll in a chemistry class at my community college.

I have not had chemistry for about 12 years but was able to follow the course without any problems in order to review the basic concepts of chemistry. It's really for beginners, but still makes you feel the progress of what you've learned while advancing the class. A good balance between theoretical concepts and stoichiometrical calculation. Thanks!!

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.

Le doy 4 estrellas,bien explciado pero por motivos de mi establecimiento debi temrinarlo rapido no logre hacer los demas ejercicios con honores y aparte mu buena explicacion para retroaliementar los temas vistos

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.

The video lectures taught you how to pass the tests and didn't really teach anything well.

Great review for those who need refreshers and good for newcomers to chemistry!

Good explanations, actiivities and experimental examples.

I gained a lot of knowledge with this course.

It's a very good course and

clear teaching!

Well explained course. Thank you.

Great course for concept clearance

clear concept explanation

helpful for the biginner
