Once in FUT ultimate team, go to play, division rivals and continuously play matches.
There's a deadline, so watch out for that. If you scroll to the right, it'll tell you how many points you need to get as well as the points you already have.
At first you won't get as many points. Each division you enter, your points will increase. For example you'll get 5 for losing, 12/15 for drawing and 30 for winning. Next it's 6 to lose, 16 to draw and 40 to win, etc.
