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.

this is an amazing introductory course to chemistry as I have learned a lot of things and how to change from ratios, how to naming compounds, how to calculate the solubility product, periodic table, and some trends and a lot of other things

Indeed an introductory course but is also suitable for adult learners. Lectures are logically ordered and clearly explained. Separation of content into weeks is motivational. Highly recommended for those who want to get into Chemistry.

It's a great course! First of all, this course helped me understand and open my eyes to the world of chemistry through the concept of energy. This has helped me learn a lot. I've also gained a lot of stoichiometric skills as well.

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.

I loved with all my heart the way Dr. Dorian teaches, it seemed to me that I learned things very quickly as if they were very simple. I learned a lot, I enjoyed and took advantage of it, very good rate for this course.

Dr. Canales, takes time to explain baffling calculations and that helped me pass my course. I'll recommend she review lecture on acid base and redox reaction, lecture note was too short with few examples to understand.

An exceptional course to revise previous concepts. many a times strengthened my previously vague concepts. The interviews and especially the practical videos were very enlightening.

To be honest, I knew a lot of the course (the program of the school course in my country provides for all this), but this course opened my eyes to many things in a new way

This course reinforced the basics of chemistry that I had already learned in Chemistry while also giving me to gain more in depth information from the teacher's videos.

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!

G​ood introduction to chemistry for those interested for some background knowledge. I would say this is at GCSE level, and is good for revision. Thanks a lot!
