In the quiz show, Billy recites the "To Be or Not To Be" soliloquy from Hamlet with a skull in hand. Hamlet doesn't recite that soliloquy with a skull in hand. He only speaks with a skull in hand in the grave-digger scene at the end of the play.
However, the skull was probably just a prop as part of Hamlet's costume because that is how people know Hamlet.

The entire six-month process of Billy repeating grades one though twelve could have been compressed into a single day if he went and did a GED exam.

When Eric blackmails Principal Anderson he says he has his copy of "Wrestling World Magazine" but the magazine he holds actually says World Wrestling Magazine.
If the decathlon was in one day, when Billy and Eric make pies in a home ec class. Eric's pie is on fire and he suddenly catches on fire, he would've suffered severe burns and would need medical attention or he would've died if he was burning too long. He looked fine when he raced against Billy in track in the next scene.
