IMPORTANT: you need to know how to make a takedown and how to so the Mount Position. I can't Upload pictures because i dont want to get in trouble with Copyright & other Stuff.
I used some methods from SPARTANKING8675's Solution and i tried some other ways to boost it faster, thats what i did: if you Follow his Solution You will get 100-200+ Points
If you jab (X+Y) until the Time gets 1:20 or Less, then you should take your Opponent in a takedown and do the Mount Position (you should sit on his Body) and now you should make a Submission (Press the right stick for the Arm Bar) and win the Match. If you did everything right you should get 6-8 medals (the Submission gold medal, and sometimes the 10 wins in a row medal will coming too) with 200-300+ points. I dont know if you get more XP when you are in a high level but i get always 200-300 points so thats all i know. Its hard to Counter a jab for the 2.0x multiplicator, i tried my Own way and i am Level 40 now.
