Xbox360 Achievements

hey sup,I want to know if it's possible to share your achievments with your brother or friends,because I completed alot of achievements with my brother's account now i got my own,I dont want to play the game over again to get the same achievements completed,is their anyway to share or do anything to get the same achievements back on my new account?thanks for any help!!!

I am no expert in the matter but I am pretty sure that unlocking a achievement is exclusive to the account you do it on otherwise everyone would just trade em and have thousands on top of thousand of points each.

Yeah, you are out of luck. They don't allow them to be transfered for obvious reasons. People would just pass around the files.
