I have only seen one or two people try and write down stuff that we learn in class. Im more of a visual person I guess, I just see something and I remember it. I only need to see a move a few times to remember it permanently. Ive never been much of a studier, especially in Jiu Jitsu.
Just curious, what kinds of things do you guys record? Steps to moves? Lists of moves from various positions? In my experience with moves with numerous steps it is difficult to list each step in order, because some moves require multiple steps to be done at one time. Like with an armbar from the guard for example, after you trap the guys arm and reach across you have to take your arm that is on the same side as his trapped arm and reach across and grab your opponents shoulder, while at the same time putting your same side foot on your opponents hip, trapping it tight to his body so that he cannot escape to that side. While you could do those two moves seperately, to be really fast with an armbar you want to do both at the same time. I think that is too much to write down for one move, it should just be something you remember.
