my tutee texts me at midnight asking about subjects i don't even teach

so this student keeps texting me in the MIDDLE OF THE NIGHT asking me shit. i've literally told them a million times not to message during my personal time but here we are, me getting dragged out of bed at this hour. like why are you asking your MATH tutor about science and korean. the commitment is insane honestly. and it's just. so unhinged that they're studying at this time. anyway i've basically turned them into a 1st grade average student so.

EDIT: ok so i just threw some random physics handouts at them during a break and answered a few questions right, and this kid just... absorbed it all on their own??? turned a 4th grader into a 2nd grader student by themselves. and now they're out here acting like it was MY genius work lmaooo. he's a guy btw and honestly the midnight text annoyed me but like. seeing how smart he is when he actually understands stuff? im so full rn. literally where did this kid get his brain from. i'm obsessed with him
