Effective study techniques for UPSC aspirants include creating a structured study plan that allocates time for each subject. Utilizing smart resources like NCERT books and standard reference texts is essential. It’s beneficial to engage in active learning through discussions, summarizing topics, and solving previous year’s papers to enhance retention. Aspirants should also practice time management, ensuring a balance between various subjects and revision. Regular self-assessment through mock tests is crucial to gauge progress and identify areas needing improvement, thereby optimizing preparation.
