“Schooled,” is a spinoff of the hit comedy series, “The Goldbergs.” Set in 1990-something, the series follows the hilarious faculty of William Penn Academy, led by new music teacher and WP graduate Lainey Lewis (AJ Michalka), Principal Glascott (Tim Meadows), Coach Mellor (Bryan Callen) and young, enthusiastic super-teacher Charlie Brown, or CB for short (Brett Dier). Despite their eccentricities and crazy personal lives, these teachers are heroes to their students.
