/sci/ - Science & Math

What does /sci/ use for grinding practice problems / taking notes? I feel like I'm going through an insane amount of paper(could be more efficient space wise). Also limited desk space.

I'm thinking of getting a whiteboard but just taking a pack of paper out and continuously doing problems seems so easy.

I'm sure there are good electronics for taking notes, but every device I've used with a stylus didn't come close to writing on paper with pen or pencil.

Just curious on how others do this and what they think is best / most efficient.
