Aspirants can utilize management theories such as the Pareto Principle or SMART goals to create effective study plans for UPSC. The Pareto Principle suggests focusing on the 20% of topics that yield 80% of the results, while SMART goals help in setting specific, measurable, achievable, relevant, and time-bound objectives. These theories encourage candidates to prioritize their study material based on relevance and difficulty levels. Implementing frequent reviews and adaptation of strategies grounded in theoretical frameworks can lead to organized and efficient preparation.
