Common pitfalls for UPSC candidates include mismanagement of time, neglecting current affairs, and underestimating the significance of mastering basic concepts. Some aspirants may focus excessively on advanced topics, overlook syllabus coverage, or skip revision, leading to gaps in knowledge. It's also common to fall into the trap of excessive reliance on coaching materials without developing a personal study plan. Candidates must ensure a balanced preparation strategy, incorporating both depth and breadth in their study, while consistently practicing effective time management throughout their journey.
