Assuming everyone graduated at the age of 18, plus 4 years of college that would be 22 years, still younger than Chifuyu. Assuming Maya just took short courses of measly 1-2 years, she would be 19-20.
Besides, Maya's subject IS related directly to I.S., since there's no I.S.-related college, safe to say that it is possible for her to become a teacher without goign to college at all, probably short courses about how to become a teacher, or something. And even then, she's still ASSISTANT teacher.
Do you honestly think a High school graduate can be accepted as a math/literature teacher?
