New Super Mario Bros. Wii 7-4 QSC

I got the 1st Star Coin by bouncing off a Banzai Bill at the end of the first part of the level. When near the 2nd Star Coin, I tilted left to make all of the platforms line up. I jumped to the Star Coin and landed on the tilt platform below. At the end of the 3rd part of the level, I bounced off of a Bullet Bill into the red pipe above. The 3rd Star Coin is at the top of a staircase of Bill Blasters. I got it, took damage, and made it to the goal after going through the next red pipe.
