Studying in short sessions beats cramming, and the research is clear
A short, useful read for the Crazish community.
Spreading practice over several short sessions produces far better long-term memory than one long sitting, even when the total time is the same. The brain consolidates between sessions, and each return to the material strengthens the retrieval path. Twenty focused minutes a day for a week outperforms a single two-hour push the night before an exam.
Pair spacing with self-testing. Instead of re-reading notes, close the book and write down everything you remember, then check what you missed. The effort of recalling is what builds the memory. A simple deck of question cards, reviewed at growing intervals, turns this into a habit that costs almost nothing and works for languages, law, anatomy or code alike.
