has anyone went to a career center for medical assistant? If so I have a few questions about it!!

So I’m 21. I graduated from high school, I went to a career center for my last two years of high school for cosmetology. I have always been in a slower math class & we never had to actually know multiplying & dividing without a calculator. I’m wanting to go to a career center near me for medical assistant. It’s 9 months long , 900 hours and it says there is some math. I’m not sure what to do. I know basic adding and subtracting/ some multiplying it just takes me time to solve I don’t know them off the back.. am I not gonna be able to do this if I’m bad at math 😩
