When I did beat it without math, it gave me "finished language level with math" (the SMART BOI Spongebob poster) instead, which is really weird, considering I did not collect a single math notebook. If you scroll down the comments and look at my language level victory video, at the end of the video I went to the achievement board and there is the incorrect achievement I earned right there. Well, at least I don't have to do Viktor's notebooks in language anymore, that would be sanity-draining, in real life, not virtually.
