I think I'm gonna get a tutor for this
Someone who can draw me diagrams and squiggles etc.
also the lower energy electrons experience a lot greater nuclear attraction as they're closer to the nucleus, and electron shielding reduces the attractions to the outer electrons.
My college gave people free 1-to-1 tuition if they were struggling, maybe look into something like that? I tried it for maths and didn't find it particularly helpful but I know people who found it a lifesaver.
