Today about 20 KMG Japan students had their P1 and P2 test (1st and 2nd level) in Tokyo. The test was 3h30 minutes long during that time students had to demonstrate their knowledge and skill to execute the techniques of P1 or P2 level.
Passing grades is very important to progress in Krav Maga, because it forces students to memorize the technics and practice them as well as they can in order to pass their test.
In Krav Maga (KMG) we have 5 degrees in Practitioner Level (P1 to P5), 5 degrees in Graduate Level (G1 to G5) and 5 degrees in Expert Level (E1 to E5). the next level after E5 is Master.  It takes about 3 years of regular training to reach G1 and about 3 to 4 more years to reach E1. So after 7 years of regular training and dedication to Krav Maga one can become Krav Maga Expert. It is a journey sometime hard but very rewarding.
Krav Maga is a way of life.
