unfortunately, most of the "old" students only comes 1-2 times a week while I come to almost every class (6 classes a week). so in most of the classes, we almost always get overwhelmed because the new students to old students ratio is about 4-5 : 1
There are two reasons why this might happen.
One is good: the dojo is new and growing, so there aren't very many senior students and there's a steady influx of new students. But over time, you'll accumulate more senior students and the situation will improve.
One is bad: no one sticks around long enough to get really good. And perhaps now you know why not.
