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.

The teaching method of Dr. Dorian canelas was very simple and impressive. I have learnt a lot and much enjoyed during the lecture and Practical demonstration. I recommend it to all chemistry learner.

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.
