The total number of episodes in the series is 20 episodes per season* 12 seasons = <<20*12=240>>240 episodes

He watches 1/3 of the series, 1/3*240 = <<1/3*240=80>>80 episodes.

A total of 240-80 = <<240-80=160>>160 episodes were remaining for Cesar to finish the series

If Cesar watched 1/3 of the series before the school closed, how many episodes were remaining for him to finish the series?
