McDojo gotta McDojo...At my current dojo, no one has ever said this. At my last dojo? Everybody was saying it. It was a heavily padded curriculum that, if the planets don't align correctly, might not all be covered before the next test. You had to hope and pray that what you needed was being covered on the days that you showed up and that you didn't miss it on the days you were home. And they didn't tell you ahead of time, because they didn't want people showing up only for the days they needed.
This isn't a problem at my current dojo. No padded curriculum, and all three K's are covered everyday.
