[A K]

my total gamerscore is 2975, is that a high gamer score. o wait back to the halo. Any way i've erned 770 gamer points from halo. the only achevments i can do are the marathon thing (whitch i dont know where all of them are) and all the other things where you have to get 15,000 points on most the levals and 50,000 one that one leval. but any way what is the most gamerscore you can get out of it?
o can you tell me or send me a video on how to do every thing i havent
