Jiu Jitsu Question - Please Help?

BJJ and Jiu Jitsu are very similar aside from the evolved tactics of BJJ. Jiu Jitsu was brought to Brazil by Mitsuyo Maeda in 1914 and the techniques have been evolved according to the different applications used today. Jiu Jitsu started out as combat techniques for the japanese army but turned into a popular practice in Brazil after Maeda introduced it. No need to change schools, i'm sure your instructors are well aware of all techniques practiced in the sport.
