Excellent course!!! I enjoyed the historical background the lecturer used including the brief synopsis of the Chinese emperor consuming mercury pills to gain immortality.

Excellent course. Although, it was very challenging to me to complete it and I had to repeat some of the videos, I am very happy that I decided to take it. It helped me to repeat my knowledge.
