"Back to School" is a song composed by Deftones. It is an altered version of the song "Pink Maggit" off the band's album White Pony. The album was re-released with the song shortly after the album's initial release, in a contentious move by the band's label.

Vocalist Chino Moreno elaborated: "This album right here [the White Pony re-release] is not the album that we turned into the label. As far as we're concerned, the first edition was the record. Done. Then they talked us into re-releasing it with another song on it, and it's not like I'm against the song or whatever, but I liked the sequence we had when we first turned it in. When this version came out, a little part inside all of us felt like: 'Fuck! We just totally compromised.' And I know that a lot of our fans felt bad about it too."
