3. I Was a Teenage Abomination

Complete story — includes the ending

Luz is dissatisfied with Eda's "training", but perks up upon learning about a school that teaches magic called "Hexside School of Magic and Demonics", something Eda opposes, as she dropped out. Luz meets Willow Park, a young witch who is picked on by top student Amity Blight for her inability to create abominations. Luz pretends to be Willow's abomination so she can get a passing grade, and also meets Gus Porter, a human-obsessed student. Luz successfully fools the class' teacher with her disguise. Meanwhile, Eda and King make a bet to see who makes the better teacher with King winning due to Luz having gone missing. However, King's "student", a slug named Prince Jr., attacks them forcing King to rely on Eda once again. Amity realizes Luz is not an abomination and calls Principal Bump to examine her through dissection. Gus creates a diversion and a chase ensues, where Willow shows her skill at plant magic. Willow is exonerated as an astonished Bump reassigns her to the plant courses. However, Gus informs Luz that she is banned from Hexside. Gus and Willow offer to teach Luz what they learned, but she happily accepts Eda as her teacher instead.
