How do you guys feel about belt tests in Jiu Jitsu ? The only bjj school in my area requires you to take a test for your blue belt and for purple. I don't like the idea of belt tests at all, but the worst part about it is that they charge you to take the test. Its like 100 bucks for the blue belt test and I heard its way more for the purple test. It makes me think they are just in it for the money. Do any of you guys train at a school like this ?
