Class has been dismissed.

The Doctor Who spinoff, which made its stateside debut in April, has been cancelled after one season.

Damian Kavanagh, who heads up BBC3 — the U.K. network where Class originally aired — confirmed the news on Thursday to British magazine Radio Times: “There was nothing wrong with it. I thought [writer] Patrick [Ness] did a great job; he explored an amazing world. In honesty, it didn’t really land for us on BBC3. Some shows don’t, and I have to make decisions about what we’re going to do from a drama point of view.”

Described as a “British Buffy the Vampire Slayer,” Class was set in present-day London, where four teens were tasked with protecting Coal Hill School.
