Mixing new students with old students has always been hard for me. you don't want the old ones to feel stagnant and the new ones to be confused. I have picked up on doing warm ups like Bravo does. I've put together some other flow drills I like as well. It has helped close the gap lots, without boring either spectrum. Bravo's ideas not just techniques has helped me progress as a grappling instructor a great deal. Being I was stuck on just striking for a very long time. This forum and pro membership has been an infinite trove of help, you are in the right place. A solid stage building curriculum, so they can track their progress as far as techniques learned, helps them as well. All students like to be able to track their progress. A curriculum, while not a true determination of skills, does make your class look more professional as well. Then you gotta build them up, think used car salesman teaching jiu jitsu. The best teachers out their lose their students to horrible teachers because of their lack of business skills. My instructors hardest part in the beginning is not talking loud enough or clear enough, even though they have the skill the confidence isn't there, if students don't think you have the confidence then they don't think you have the skill.
