The UPSC syllabus serves as your ultimate guide. Many aspirants begin their preparation by blindly reading textbooks without aligning their study sessions to specific syllabus topics, leading to massive time wastage.
2. Overloading Study Materials
Gathering too many books, coaching modules, and PDFs creates confusion and mental fatigue. Instead, focus on a single core textbook for each subject and revise it multiple times rather than reading ten different sources once.
