I don’t know about you, but I rarely referred to my notes later. The lectures frequently corresponded to the textbook, so I’d review the textbook again in light of what the lecture covered.

For me, handwritten notes were much more effective than digital notes because I rarely actually used the notes and taking notes was more to keep my attention on the speaker than actually recording the lecture.

Everyone works differently of course, I’m just pointing out that my experience was close to what the studies measured.
