Effective note-taking during lectures can significantly enhance understanding of the UPSC syllabus. It encourages active participation, helping students to distill important information and concepts during live discussions. Well-organized notes serve as valuable study material, aiding in swift revisions. Using techniques like mind mapping or the Cornell method can further improve comprehension by highlighting key concepts and their interrelations. Additionally, tailored notes can address individual learning preferences, making study sessions more productive. This practice not only aids retention but also facilitates critical analysis when faced with exam questions.
