Am I stupid or what?

Okay so I (23F) am struggling hard with my college pre-calculus algebra class. To preface, I go to a community college, and I was homeschooled.

My homeschool education was decent but lacking, my parents definitely lied to get my high school diploma.

My college structures their math classes where homework is 33% of your grade (and some change) the midterm is 33% and the final is 33%. No makeup work, no exceptions. I’ve failed this class three times.

I feel incredibly stupid for this, but I also recognize that my foundational education was poor. It’s no excuse bc I’m an adult now, but I don’t know how to go about advocating this situation to my teacher.

I just had my midterm and I made a (12/33). In my homeschool career I was rarely taught algebra, much less calculus. Hell, I was taught latin and cuneiforms before math.

Tl;dr I suck at math to a potentially disordered level, any advice.
