How to Get the 'Iron Boy!' Achievement in Super Meat Boy

YouTuber sockcornnoodles is a punk. Not only does he have the best user name ever, but he's able to make it through a single chapter of Super Meat Boy without dying. Which also got him the 'Iron Boy!' achievement, worth a measly 10G on Xbox 360.

Super Meat Boy is already hard enough. But to get this achievement is sheer torturous. I can barely make it through a single level in the game without dying. But to get through an entire chapter without dying? Yeah, no.
