My highschool had the same thing, they made it sound mandatory but a handful of us found out they couldn't force you to take it. So yea while 99% of my classmates took it the 5 of us got to sit in a empty classroom and wait it out
People act like the alternatives are any better but they really aren't. Sure don't get me wrong it sucks that you typically have to scroll through useless info to find what you're looking for, but I put that on the server owner, you see the same issue on most forums too.
