Can having an intellectual disability affect your academic performance in college?

I am currently a college student at my local community college and notice that I fail every math and science test even with help. The science I am taking is anatomy and physiology whichI am failing. I also take too long on tests. I have mild intellectual disability. In some subjects like psychology and health I can pass. Why is this related to my disability on why I keep failing math and science? I struggle with those unlike typical students in my class. Can an intellectual disability can be a learning disability because I can fail tests easily and take too long on tests? What causes this?
