I do not have dyslexia. I’ve been reading since I was a little kid. I don’t easily recall words or things that I’ve heard. But I’ve got a very good visual memory, especially remembering patterns. And I can easily visualize things too, even the somewhat abstract concepts.
So if I put a visual bend on something I can quickly understand it and remember it, but that bend has to be mind (even when helped by an image on a book). If it’s someone else’s, I’ll be very hard pressed to remember it (but I can easily remember where it was).
So at school, when I had to cram, I fill my head with images and things like that. And with the help of the exams (written) and memory of the classes, I worked out the answers.
