Win an NCAA Ultimate Team championship.

This can be boosted. Play online when its not too busy, such as 11 PM to 6 AM. It should take 11 games from start to finish to earn this for one player. From main menu, go Ultimate Team > Play Game > Head to Head > Play X Season Game > Find Game.
Once you win all 11 games, you will unlock the achievement. Once you do this it will be harder to be matched with your partner, but still fairly easy if youre playing at odd times.

Note: Make sure you talk with your boosting partner and back out if you see youre facing a team that your partner is not playing as, this help avoid playing randoms.
