I ve been training gi and no gi jiu jitsu for about a year and four months....I ve placed in 6 of the 7 tournaments i ve been too and the latest one's i have won first...I am only 140 pds and everyone in our school is big...the second smallest guy is 155 then everyone else is above 170...I beat everyone except for my purple belt instructor which I have beaten twice but I m sure he wasnt trying to hard, and a few good but a lot bigger blue belts...I have tapped about 3 bluebelts in tournaments in no-gi....We finally have our blackbelt come down in about three weeks to test us and see if we are ready....Do you think I am ready to be a blue belt?....Does it matter how big or small you are compared to your gym mates when you get tested?
