The 80/20 rule in UPSC means that 20% of the high yield topics and smart efforts can create almost 80% of your results if studied smartly. Instead of covering everything, aspirants focus on some core areas which are repeated in the Civil Services Examination conducted by Union Public Service Commission. This approach which is often referred to as the UPSC 80 20 strategy, helps in better retention, saving time, and more chances of selection when combined with consistent revision and mock practice.
Let's know how this UPSC smart study technique works in real preparation.
Understanding the 80/20 Rule (Pareto Principle)
The 80/20 rule or Pareto Principle suggests:
80% of outcomes are achieved from 20% of focused inputs
In UPSC preparation this means:
-
There are a few UPSC high yield topics from which the majority of questions are asked.
-
Core books and PYQs are more beneficial than scattered resources.
-
The approach of smart revision is more powerful than reading too much.
However, it does not mean to ignore the rest of the syllabus. It means having the wisdom to be deliberate in prioritizing.
