How do you tell when a dojo is a "mc dojo" (basically just awful at actually teaching)?

Your school sounds very legitimate. The only question is the quality of instruction, and I can't tell from your description. You mention some "bad" points.

Let me address them individually, and you will see that they can be good points, if done properly: 1. We have 1 seminar each year (someone told me that seminars are a sign of McDojos) but it´s not mandatory and it cost $12. Seminars give you opportunity to experience different instructors, students, and even styles.

At $12, this is a steal. Take advantage of them when you can. If the school holds their own seminars, then not so great for you.

2. We don´t usually go to tournaments, my proffesor believes that martial arts are not for showing off, but I guess you are not forbidden to enter one. Not being required to go is a GOOD sign.

Being forbidden to go is a bad sign. Being required to go is a bad sign. 3.

One school (not in the one that I train) is part of complex and they rent the Dojang for parties. At $28 per month, and $12 for seminars, someone's got to pay the bills. Give them a break.

Join the party and have a soda. On me. 4.

The exams for the first belts are too easy IMO but i´ll give them that in advanced test of about 10 students only 3 or 4 passes, Btw the black belt exam takes like a whole day or so. 30%-40% pass rate? Any time there is a potential to fail a test, that's a GOOD sign.

It means you must work at your test, it won't be a given. That means, you have an incentive to do better. How can this be a bad thing?

5. We do board breaking (again I heard this is useless and it´s a sign of a McDojo).

Without actually witnessing the class I can't say it is or isn't a mcdojo. It doesn't sound like one from what you described. Board breaking is not a sign of a mcdojo and neither are having seminars.

The biggest signs in my opinion of a mcdojo are belt being issued out too quickly, children black belts, young high ranking black belts, black belt guarantee. Poor quality of instruction, long term contracts. The list can go on.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
