This course is excellent. I had done a lot learning on learning to do 4 different certifications (PMP, LEED AP Homes, LEED AP EBOM, 6 Sigma Black belt in Quality Mgt., and LCC in Wellness). Although I had been exposed to some of the techniques, I got a better understanding of why they work for me, e.g., the memory challenge/palace. But, I also learned several new techniques. Instructors were clear. Coursera is great because you can speed up the video to 1.25 up to 2 or even slow down if English not your primary language. I may use a Coursera course in Spanish at slow to get fluent. This course is worth the time if you practice the techniques and make yourself believe in adequate sleep, exercise, and activity as underlying foundations.
