| I would suggest that people should use notecards for subjects
| that are math heavy. Even if you don't fully _learn_ by using
| notecards. Even then.
|
| When you use notecards, and stick to a spaced repeatation
| algorithm, if nothing else happens, you at least get to
| familiarise your brain to notations, jargon, graphs, diagrams
| and so on. This especially helps if you are learning alone.
| When none of your classmates or colleagues or mentees is
| learning what you are learning, i.e. you are not in a classroom
| or training program.
