So I just joined Gokor's tonight, and now I'm going to be taking the MMA class without gi once a week, the Judo/Jiu-jitsu/Sambo class with gi once a week, and drilling the shit out of all the stuff they teach me on those two days throughout the rest of the week with my other workout partners. I'm a total newbie when it comes to grappling, but I intend to take this very seriously and learn as much as I can. I'm 25 now...how do you think it would take me to get to black belt? 35? 40? Do I have to win any tournaments to recieve a black belt or do I just take a test?
