Of course you learn more if you retype material than if you do nothing, but it's still a waste of time, comparatively speaking, because there are much better ways of engaging with the material like solving practice problems.

Having to spend 95% of the time taking notes of things that could be distributed in a PDF has only ever hindered me academically. It's mechanical and boring, my mind tunes out and I get nothing out of it.
