Note-taking vs. repeated practice questions — which is more efficient for SPI?

Short Answer

Any advice on this is just a reference point, since no one else actually knows how you learn — you have to figure that out yourself first. Concept-first learners, who need to fully understand one idea before moving to the next, tend to do well with note-taking: work through one concept at a time and write it out. It takes longer, but what you learn this way tends to stick for a long time. Pace-first learners, who'd rather quickly grasp the core idea and review it repeatedly — even just by rereading — and who like jumping straight into practice questions to learn by doing, tend to do better with repeated question-solving: test, spot the gap, patch it immediately.
