Open educational resources (OER) play a transformative role in UPSC exam preparation by providing free and accessible learning materials. These resources include online courses, e-books, and interactive platforms that cater to diverse learning styles. OER encourages self-directed learning, allowing candidates to explore subjects at their own pace. This democratization of knowledge enables aspirants to access high-quality content irrespective of their economic background. Furthermore, leveraging OER can help candidates stay updated with current affairs, enhancing their understanding and retention of critical information relevant to the UPSC syllabus.
