Most colleges will have a student disability office that you should connect with. I get PDF copies of textbooks for me that could be used with a screen reader. They also provide screen readers to you at no cost.

Talk to the disability office and see what they can provide. They should be able to provide books in aalternate format. I suggest you ask for them in docx or in some text file format. Not all pdfs are made equal and a lot of publisher pdfs are lousy! If you’re taking, math, stats, or science ask for braille versions of books.

They should be able to give you extra time or have professors adjust your time for you, if it’s stated in your acomodations that you need that. Make sure things are accessible, your lectures can be recorded you can have a notetaker as in a person take your notes for you. Some colleges you can ask for extra time for homework or have the chance to ask for it when it’s necessary. The disability office can provide you a way to get a screen reader, as long as you’re in some education I think Jaws allow you to have a copy. If you need to convert your research pdfs to doc you can also have them do that.

I use the disability office at my online college for a screen reader and extended time on tests, for us slow readers. Contact them to let them know your issues and they will let you know what they can provide. Good luck on your degree!

What others have said. Also be a strong advocate for yourself. Sometimes these offices are overwhelmed and while they mean well they may be resource and time strapped. So speak up! Email your professors and let them know your situation and that you have contacted the disability office. That way any requests you make for assistance aren't coming out of nowhere. Good luck! I'm sure you will do great!

Most colleges have a student disability office and you are assigned a counselor, they will help you register for classes and help you with your accomidations

It will be difficult...
Be prepared for some platforms not being fully accessible, them shoving their nose in every tiny personal accomodations you need to make, just for yourself, so you can even do anything, and for every single test observer to get upset with you for being disabled and making their job harder...
DO NOT let it stop you. These are things I'm just informing you to be prepared for. Heck, it might not happen to you! I hope it doesn't! But be prepared to work extra hard when needing to get certain things done. Be prepared and talk with the disability support services at the college before you even start. If they try to feed you some garbage about you needing to enroll before they can give you any advice, tell them that is against the law (if you're in the US), and that you need to prepare as much as possible before you go chasing a degree.

Depends on the degree. I'm an Information Systems degree and I've struggled for so long trying to have my classes be accessible, so your mileage may vary.
