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.

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