Aspirants can use reflection journals to track their learning progress effectively for UPSC by documenting their daily study habits, insights, and challenges. Regularly writing reflections allows candidates to identify strengths and weaknesses, helping them adjust their study strategies accordingly. Journals can also include summaries of important topics, exam performance evaluations, and future goals. This process of self-assessment encourages critical thinking and promotes a deeper understanding of the syllabus, resulting in more focused preparation.
