What is TOK even about

Like, what do you mean I have to write a whole ass essay/presentation or whatever about a question I don't even understand myself???? What's the point of it. I mean, I do see the point of it, but with the way it is executed in my school (our TOK teacher just yaps for over an hour per week, while I try not to think about my imminent doom in the next Math test) I would be better off doing literally anything else😭😭😭

Sorry for the rant but I needed to get that outa my system. I guess I have a question: How did you choose your TOK question?? Was/is your journey with TOK as much of a hassle as mine? Big appreciate if yall answer🙏
