You can get accommodations for learning disabilities, but as others said, you need to get tested and the test information needs to go to your college so you can get accommodations.
Getting Ds and Fs at a CC generally means college is not for you, and you should look into trade school.
But if there really is an issue, neuropsych or learning disability testing (sometimes neither is covered by insurance) would be the way to go.
I also think “seeing the professor once” and not always reading the book is a recipe for disaster. It’s like you weren’t giving yourself a chance. My son did poorly his first semester of college, and one thing that helped him a lot was using study groups, and seeing the professor or TA for each course.
