Candidates should review their study goals at least weekly during UPSC preparations to ensure they stay on track. Regular reviews allow aspirants to evaluate their progress against the established plan, enabling them to identify areas that need additional focus or revision. Adjusting strategies based on performance in mock tests and feedback can enhance the effectiveness of their study plan. Additionally, maintaining flexibility in study goals allows candidates to adapt to changes in the syllabus or newfound interests, ultimately leading to a more comprehensive understanding of the subjects.
