Skipping Classes and Dropping a Non Credit Class

Okay i sometimes dont have the heart to go 2 any classes and i have good grades i just dont like going to class, but my question is can i drop my math class and retake the placement test and get into a high math because i didnt try on my placement and it landed me with a Pre-Algebra which is a math for the ppl who are not good at it ?

What grade level are you talking about?
I have no idea, that is a question only your school can answer for you.
And if you’re skipping classes so much now why would you want to go to college?
