Expert’s analysis 

The expert analysed the paper as difficult, and it followed the pattern of previous years. According to Abhishek Patil from skholar.com, “The paper has mostly shifted to application based than from current affairs. This year, the paper was ruled by questions from science and technology, economy, while questions from history and geography were generic. This year, UPSC asked questions from the field of agriculture to recent trends on MSP, agri procurements, and on eco- friendly agriculture practices.”
Manoj K Jha, Director of GS score said, “The cut-off this year will remain identical to last year as the paper is unconventional, with questions from current affairs demanding conceptual clarity to solve.” The questions from science and tech, and economy were application-based and touched the recent developments worldwide. The questions from political science were conventional type while questions from geography were mostly from agriculture. “
