I know that my EPAK instructor required a written, 3 page thesis from each student who was testing for black. The topic was to be something along the lines of What I Learned from Kenpo Karate, or How Kenpo Karate has Affected My Life. Sadly, I was never able to read any of them myself but given the different ages and backgrounds in the dojo I'm certain it would have been very interesting stuff.
I'm assuming a thesis is not uncommon for testing for black? What guidelines do your senseis give for topic and length?
It might be interesting to read some of your theses, if anybody would be kind enough to share them with MT. Perhaps some of you would post your thesis here?
