Forgetting after revision is a common problem in UPSC preparation, and it usually happens because revision is passive rather than active. Many aspirants simply reread notes or highlight text, which gives a feeling of familiarity but does not strengthen long-term memory.
Another reason is long gaps between revision cycles. When topics are not revisited regularly, the brain gradually forgets information. UPSC preparation requires short and repeated revision cycles so that concepts move from short-term memory to long-term memory.
Information overload can also affect retention. Studying too many sources at once makes it difficult for the brain to organize information clearly. Limiting resources and creating concise notes makes revision more effective.
To improve retention, focus on active recall methods like writing answers, solving PYQs, explaining concepts in your own words, and revising through frameworks. These techniques force the brain to retrieve information, which strengthens memory and reduces forgetting.
