A bullshit system used in IXL, apparently used to measure student's knowledge on a certain topic. It seems to work in theory, but in practice it's rigged against students, it aggressively goes through various different topics, without taking time to make sure the student is actually learning instead of wanting to blow their brains out.

Timmy's Mom: "Shit Timmy... I'll just home school you at this point."
