Candidates should approach the compilation of current affairs for UPSC by maintaining a systematic method. Regularly reading reliable newspapers and designated monthly magazines is essential for staying informed. It's beneficial to maintain a dedicated notebook or digital folder to summarize key developments, categorizing them by themes relevant to the syllabus. Engaging in discussions, and utilizing quizzes or group studies can enhance understanding and retention. Revisiting these notes periodically and integrating them into daily revision allows for a nuanced grasp of pertinent issues leading to better exam preparedness.
