This past weekend, I started taking classes at a local school that teaches a bit of everything (judo, brazilian jiu jitsu, karate, kickboxing, nhb, etc.). When I signed up for classes, I specifically stated that I am interested in learning bjj. The instructor told me fine, no problem, sign on the dotted line and I can begin training in bjj on the weekend. I get to class on saturday morning and once again, told the instructor I am really looking forward to training in bjj to compliment my standup skills. So I go through the class and at the end, I hear them announce that one of the students is going to be competing in a judo tournament. Then I hear one of the other students say that he wouldn't be able to make the next judo class. So at this point I finally put 2 and 2 together and I'm thinking okay, the instructor knew I wanted to learn BJJ and I even confirmed it with him prior to the beginning of class, and he never said anything about it being a judo class. So, I went to the teacher and asked what the deal was. He told me saturdays alternate between judo and bjj, and that particular saturday happened to be a judo class. Then he says "well, on weekdays we do all the grappling training together; we teach techniques from all the grappling styles together". So in other words, they sort of lump everything into one class. There are no specific classes in bjj, judo or any of the other styles they claim they teach, it is just all lumped in together. Except of course for the weekend, in which a whopping 2 BJJ classes are given per month. Had I been told this from the beginning, I would have gone elsewhere as I am not interested in learning judo (have nothing against it, just want to learn BJJ). Now I am stuck in a contract for 6 months. What I would like to know from the more experienced grapplers is, since it seems as though I will be taught a hodge-podge melting pot of grappling techniques, how can I tell which ones are actually BJJ and which ones are judo? Are there certain types of locks or submissions that set the two apart? Should I just take my business to an actual brazilian jiu jitsu academy instead of playing "name that style"?
