Is she even allowed to do this?

My mom told me she’s taking me out of school tomorrow because she wants me to go help her house cleaning. Tomorrow is a B day when I have ALL my core classes. I cannot be absent because i take ap classes and we learn something new everyday, I will fall back. Plus I have a quiz that will affect my grade if I don’t take it & i will get an NG (no grade) that ima have to make up but our report card go in Friday meaning wtv grade i get for things I miss will go in to show my work this past semester. Btw, I am a junior. I understand she wants help but I’ve missed too much already (excused absences because doctor appointments) so I can’t miss any more as my lowest grade is an 89 & if I get below an 85, I’ll get kicked out of my honor society
