How did any of the 4 even get into the “nerd” school? I can imagine that maybe one or two of them are failing due to other issues, but at least the MC seems to be completely ignorant of basic math, apparently can’t even understand his own cheat sheets, and has a volatile temperament and appearance that doesn’t seems suitable for a serious academic school.
So far it’s pretty annoying; I hope it improves fast in the next few chapters. My patience with idiot MCs is not long.
