Unfortunately, no. That only comes from personal experience and the experiences from all the project which tried to train people. I've given several courses internally in my company. I found some concepts I knew well, I cannot make them digest easily. While some graduates understand it, while others are frustrated. Then when we are having lunch, I found some of the graduates can explain them to other people in a way they can understand - I missed many details which I would take for granted.
