UPSC Prelims 2021 GS Paper 1 Question paper is out. We have observed the following general trends regarding this year’s question paper:
- UPSC has not followed previous year’s trends i.e. hard and analytical questions. This year’s questions were more basic and applied in nature, similar to UPSC trends in 2010-16.
- Some of the sections that have been completely ignored, in the previous years by UPSC, have reappeared this year. i.e. Sports and awards.
- The weightage of ancient & medieval history has been increased.
- Overall, UPSC has maintained its reputation of being unpredictable. The nature of the question paper is very different from the expectations of aspirants, preparing specifically for UPSC CSE Exam.
