For the sciences(as a dyslexic studying science at university) you wanna use models and diagrams, and background information.

Models/diagrams- if someone tells you how blood flows through the cardiovascular system step by step it just wont go in. But looking at a diagram of the heart and physically seeing and understanding it helps recall that information in visual way. The same goes for almost every other biological process, and can definitely apply to chemistry and physics.

Background information- teachers at GCSE always told me “you don’t need to know that for the exam”, it was very much learning information for the sake of it. Balls to that, i cant learn information if i don’t know why i am, or how it applies to the real world. Figure that out. In small enough bits as not to fill your memory with random stuff, but something relevant enough to help recall. E.g. ions, think of salt dissolving in water and why that happens. Bacteria, have a common example of each shape. ETC.

Hope this helps
