how do I formally complain about a teacher?

for context, i’m in shs!

i’ve noticed that a teacher of ours might not be the best fit for the subject she holds. her expertise lies in p.e and sports, however, napunta din siya sa amin for cpar.

she has repeatedly complained about the subject, our assigned textbook, and the fact that she has to discuss it. in the little times that she /has/ discussed, we can tell na nahihirapan siya.

the petas she assigns have no correlation with our subject. for our first peta she assigned an “opm roleplay-singing” when our lesson at the time was about contemporary art movements, wala ang acting and/or singing dito. to this day, hindi pa niya dinidiscuss nang maayos and our exams are two weeks away. first lesson namin ‘yon.

i don’t mean to disrespect her talaga but it’s disheartening to be stuck with a teacher who has no interest in the subject she holds. cpar seems like such an important and meaningful subject pa naman🥲

it would benefit everyone (our class and her) if she was replaced but i’m worried about causing an issue. there’s already an existing issue kasi (she found out that students were speaking badly about her, she called it “backstabbing”) and i’m wondering if this will put my class in a weird or awkward position.

i can’t disclose more info bc i’m worried about being found out😭 but best believe i have enough to make a formal complaint. just want to know how to go on about it.
