in halo 3 how does one have a high rank such as a 47 with only 2 exp?

i dont understand how level 47's are only recruits with 1 experience..please explain

you must mean a skill level of 47

Your skill level can go up as long as you play online

some people just play private matches and get their skill level up really high

but your rank and exp will only go up if you play on a ranked playlist
