1. Why does Nolan meet with Mr. Keating?

i found this "Keating and McAllister are having a happy chat in Keating's office when Mr. Nolan requests a word with Keating. Nolan explains that Keating's classroom was actually Mr. Nolan's back when he taught English himself. He warns that Keating's unorthodox teaching methods may cause long-term trouble for the boys. He asks about the walking in the courtyard. Keating explains that this exercise warned students against the dangers of conformity, while Nolan insists that their curriculum is based on conformity. Keating argues that the boys should be free thinkers, but Nolan vehemently rebukes this. He tells him to prepare them for college and nothing more."
