Aspirants can effectively distinguish between important and less important topics by utilizing the syllabus as a guideline while also consulting previous years' question papers. Focusing on topics that are frequently asked or highlighted in examination trends can help. Additionally, creating a study schedule that allocates more time to significant areas while periodically reviewing less critical ones can optimize learning. Engaging with peer discussions and expert advice can further assist in recognizing key subjects that hold weight in terms of marks and relevance in current affairs.
