To deal with difficult subjects in the UPSC syllabus, aspirants should adopt a strategic approach. Breaking down complex topics into manageable sections helps in reducing the intimidation factor. Utilizing diverse resources like standard textbooks, online courses, and video lectures can provide varied perspectives and clearer explanations. Formulating concise notes during study sessions promotes better retention. Furthermore, regular revisions, group discussions, and seeking assistance from mentors can deepen understanding. Prioritizing problem-solving skills and practice through mock tests can also aid in overcoming difficulties associated with challenging subjects.
