Hey guys, I'm a complete newbie about to dive into the world of BJJ. Been doing some scouting of a few different gyms in my area. One in particular does not do open mat sessions, just strictly instructional classes with frequent drilling. I would think a new, ready-to-learn guy like me would be all for open mats. I'm not sure what to make of this, is it something I should even worry about? Thanks for any input.
