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.

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