Starting UPSC preparation early offers several advantages. Firstly, it allows candidates to build a solid foundation in fundamental concepts, making it easier to grasp advanced topics later. Early preparation also provides ample time for revision, ensuring deeper understanding of syllabus areas. Additionally, candidates gain the opportunity to explore diverse resources and engage in extra-curricular activities, which can enrich their perspective. Lastly, an extended timeline can help reduce stress as the exam date approaches, offering better adaptability in tackling unexpected challenges.
