For preparing for the Indian economy section, recommended books include "Indian Economy" by Ramesh Singh and "Economic Survey" for contemporary analysis. "Upsc Economics" by Dutta and Sundaram serves as a good foundational text. Aspirants should also refer to the Budget documents and various government reports. Regularly updated resources like newspapers and current affairs magazines help bridge the gap between theory and real-world applications. Combining these with practice in previous year questions enhances comprehension and retention of economic concepts.
