Easyest way to lvl 50 in halo 3

[The Captain]

i seem to be stuck at lvl 47 and cant get any higher to save my life

there's honestly no easy way, once you're up there, just keep trying, if you get 2nd a bunch of times, that's ok too, it'll take longer, but you'll eventually level up

ranked matches seem to level up faster

You can boost but thats cheating... And can get you banned from xboxlive.
