"It's useful in the sense that the program is short, but concise and comprehensive. Quite useful for working adults who have busy working schedule, and free short time gap eg: half an hour a day is good enough to complete 1~2 sessions."

"It was very easy to learn as it’s fast and I was able to complete it on the go. Information and pointers used were also succinct. This app is great!"

"This program is very useful to gain knowledge. Due to my tight work schedule, this is the best way to learn and I like it. I can learn on my own time and own target, whenever I am free even at home."
