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.
