Wait... how much is the school paying him? From the sounds of it he is ridiculously overqualified as a teacher. He also apparently just invented a revolutionary grading system that can skyrocket the school to the best all girls school ever. If they don’t at least insist on paying him a stupid huge amount of money to let them use it (and insists he patents it and all that), then they’re just taking advantage of his kindness and the other teacher’s connection to him, and honestly that’d be pretty shitty (yes I understand good business is shitty, but doesn’t mean I like it). This seems like the type of thing that revolutionizes education; he deserves recognition, praise, and buckets of money for that.
