What is the 20 study rule?

The "20 study rule" typically refers to the 80/20 Principle (Pareto Principle), suggesting 20% of your study efforts yield 80% of your results, meaning you should focus on high-impact topics (key concepts, frequent exam material) to maximize learning efficiently, rather than spreading effort evenly; alternatively, it can mean focusing intensely for 20-minute intervals, with short breaks, to maintain concentration.
