So I was a music teacher, and I believe you're a chef. Both of these disciplines (well, i can only imagine yours from what little I know about cooking) require both good knowledge AND good skills. And learning to synchronize those is the learning of a lifetime, IMO. Disciplines like these do not grow from cramming for a test. They grow slowly over time, like a healthy tree, growing up and branching out as more knowledge and skills are acquired. THAT is what a test cannot measure....and it's the best kind of integrated learning.
