The critical literature review is essential for aspiring UPSC candidates as it facilitates a deeper understanding of various topics within the syllabus. Engaging with different scholarly articles, books, and papers helps develop a comprehensive perspective on issues like politics, sociology, and economics. This process allows candidates to identify gaps in their knowledge and strengthens their ability to integrate information, which can be paramount for both the mains exam and the interview. Furthermore, a solid literature background equips candidates with analytical thinking skills that enhance the quality of their answers and essays.
