Oh yes! You have made it to your brown belt, Now you only have one to go for your black belt! But, don't think it will only take a few months. It will take ALOT longer than that. It could even take a year maybe! As a brown belt, you will be treated as a sensei. As in when the sensei is not there, you will teach the class. You do a warm up. As a brown belt you are expected to maybe go to senior training. And you train a little bit more. A brown belt is a really important belt. Trust me, you will love being a brown belt.
Well then, have loads of fun being a brown belt and work hard to achieve your black belt. Good luck brown belts.
