Character mistake: Ms. Lewis said, "Mr. Buddy, you may not have improved your handwriting in maths, for which, this once, in lieu of your intensified efforts, we will be willing to give you the benefit of the doubt, but you have improved your score." "In light of" - not "in lieu of" - would make sense. But if a student's numbers on math homework are illegible, the teacher should NOT give the benefit of the doubt, especially when doing so changes the ranks of other students to the point of being lower.

Suggested correction: It's not known that his numbers were illegible. The audience may be led to think that he followed advice and made his numbers hard to read, but there's no evidence to prove that's what happened. The teacher saying that his handwriting hadn't improved isn't the same as saying it had gotten worse.
Other mistake: It isn't clear if the poster of the Solar System outside the school was cut off on the right, showing half of Neptune, or if the ninth planet at the time (Pluto) was accidentally omitted. IF the poster was supposed to be complete, its exclusion of Pluto would be an error for the time period (1969) because Pluto was not downgraded to a "dwarf planet" until 2006. Perhaps, only half of Neptune was shown in order to not have to address the changed status of Pluto, making this a deliberate mistake. (00:32:36)
Suggested correction: Neptune isn't cut off, it shows as a complete circle on the "poster" (looks more like a board).
