The approach to multiple revisions for UPSC subjects should be strategic and systematic. Initial readings should focus on understanding core concepts, followed by gradual revisions that incorporate deeper insights. The use of spaced repetition techniques enhances memory retention and prevents forgetting. Creating timelines or checklists for revision can ensure coverage of all topics. Aspirants should aim for active recall during revisions, testing their knowledge rather than passive reading. Incorporating different formats—such as notes, charts, and flashcards—during revisions can cater to various learning styles, making the process effective and engaging.
