How do you get ranked fast on modern warfare 2?

Answer 1

Option 1: Play Split-Screen with 3 other profiles logged in and do all of the special achievements in the barracks (Intimidation, Finishing Moves, etc.).

Option 2: Play Split-Screen with a few friends and power-level together using the above strategy.

Option 3: Get a free/cheap Xbox Live or PSN account and join a hacked server. The kill experience earned is usually increased to well over a million. Kill a person and leave! From there, you can choose to prestige from the barracks and join the server again, kill someone, leave, prestige again, and work your way up to your 10th prestige to (SPOILER) get all the prestige titles and emblems, and extra custom classes.

Answer 2

Whenever an enemy aircraft is in the air, stand still and use the m9 pistol at it to achieve an automatic nuke. Call it in and end the game. This takes a lot of practice, so don't quit on it after a few times.

Answer 3

Play the game a lot and get good at it. there is a hack, and people, including myself, get pissed off when that happens.
