This is pretty much the method I settled on while studying as well, but I use Obsidian.md just for linking while doing my "metacognition" as the author calls it. The important thing for me is that while in my 25 minute block of study that I don't go hunting for those links to my other files though, sometimes, they just come to mind. To me, that's a signal that that particular note has 'stuck' if I'm recalling it while writing about other things.
