О курсе

This is an introductory course for students with limited background in chemistry; basic concepts involved in chemical reactions, stoichiometry, the periodic table, periodic trends, nomenclature, and chemical problem solving will be emphasized with the goal of preparing students for further study in chemistry as needed for many science, health, and policy professions....

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.

I've found easier tutorials on YouTube for certain subjects but I really enjoyed the demos!

The lectures were difficult to follow, and the material on the tests were not covered well.

The professor is superbly unengaging. Her toneless voice while she reads from a teleprompter and her desperate attempts to be funny makes one doze off fast. Her gaps make it so that she doesn't really know what she is doing (might be different n an actual class). This is not story time and you don not have to treat learners like pre-schoolers. Also the advanced question sets are bullshit- just cut to the chase already and go for the answers than giving points for "did you understand the question?". Well if I didn't I would get a wrong answer and know I made a mistake somewhere, so need for you to ask exactly what formulas I'm gonna use.
