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. 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.
