I'm ADD and dyslexic so I understand where you're coming from.

It helps me if I make sing song ways to remember things. Or notecards

It helps me read faster if I space my lines out so the letters don't get as scrambled.

You could also try reading your school books like a novel, not like a textbook.

If you treat it like a story rather than a lesson it's more fun to learn.

I wish you the best of luck
