Aspirants can balance between **core concepts** and peripheral information by employing a structured study plan. Prioritize understanding key topics and then incorporate supplementary materials to broaden context. Use techniques like **flashcards** for quick revisions of core ideas while connecting them to peripheral knowledge through examples. Regularly assessing oneself through quizzes can reinforce core concepts and help identify areas that need deeper understanding. Creating thematic folders for notes can also help in efficiently organizing both central and supplementary information relevant to the **UPSC syllabus**.
