REVIEWS

LL1965
Exceptionally gifted teacher
Where were you, Professor Stevens, when I was learning this in business school?

The instructor of this course is exceptional in that he is able to make the most abstract concepts easy to understand with real, relatable real life scenarios and expertly executed animated illustrations. His humorous and engaging personal style also add significantly to the performative aspect of the presentations. The result was that I found myself mesmerized and could not wait to watch the next episode. Now, how rare is it to find a math student saying that she can’t wait for the next lecture! I’m impressed!

Encompassing and relevant
The combination of mathematics and programming/coding is the future. We need many more courese that teach this combination. Professor Stevens did an excellent job in trying to exaplain complex concepts in simple terms.
