very good for revision of topics and principles of chemistry

Excellent course! Great Prof. Canelas gave understandable, interesting and not boring lectures. I almost entirely forgot chemistry I learned in a high school and I didn't like it, but now I feel I know something and I got interest in discipline - chemistry is exciting)

There were couple minor mistakes in quizes (for example in one case the right answer was "aluminum sulfide" instead of "aluminium sulfide"), but they don't matter much.

Very Good course. It will improve the basic concepts of chemistry.

This course has helped me tremendously in preparing to return to college
