To improve reading comprehension for UPSC aspirants, key strategies include practicing active reading and summarization skills. Engaging with diverse materials, such as newspapers, journals, and books, aids in familiarizing candidates with various writing styles and vocabularies. Highlighting key points and taking notes while reading can reinforce understanding. Additionally, attempting comprehension exercises and quizzes regularly can enhance retention. Discussing readings with peers or mentors can further refine understanding and perspective. Lastly, focusing on understanding context and themes rather than just memorization helps aspirants grasp essential ideas more effectively.
