With me (I have ADHD), I would never be able to listen to an audiobook alone, I would zone out and day dream one paragraph in. But If I'm playing a game on my phone, I can listen and pay attention for hours.
I have ADHD too and while I can totally sympathize, it just doesn't work for actual learning. Unless you're some sort of genius, I guess.
For what it's worth, I cannot recommend medication enough. It took me 4 attempts to finish university before finally getting diagnosed and acing everything first try. Sometimes I still find myself amazed at being able to pay attention to a meeting, a lecture, or a book for more than 30 minutes, remembering how impossible it was before.
