Keeping a study journal during UPSC preparation is important as it fosters regular reflection and organization of thoughts. A journal helps track progress, enabling candidates to note down what they have learned, concepts that require more practice, and goals for each study session. This habit not only enhances retention but also builds discipline and consistency in preparation. Furthermore, reviewing past entries provides insights into one’s development, helping identify effective strategies. A journal can also serve as an emotional outlet, allowing candidates to express concerns and celebrate milestones during their arduous journey.
