Handwriting notes engages your spatial memory, which is incredibly powerful (see: the ancient method of loci/memory palace techniques)
There were times in college where I blanked on important information during an exam, but was able to recall it by visualizing the physical sheets I had written my notes on. I aced several infamously difficult classes like OChem and OChem 2 using that technique.
I’ve never found it possible to do that with typed notes.
Have you tried a virtual board, like Miro?
Not above commenter but I have. I have done OneNote, Miro, and several other canvas style apps. And for me it still just doesn’t click in my brain like writing it down.
