Environment as a topic for UPSC Civil Services Examination has gained importance due to increased concentration of efforts to conserve and protect the environment, ecology and Climate change on a world level, and also because Indian Forest Service preliminary exam has also merged with the civil services prelims.
The importance of this topic can be seen from the number of questions asked every year
|No. of Questions||17||18||22||21||14||12||21||18|
We can see that average of 18 questions are asked every year, making it a total of 36 marks, if we take UPSC Civil Services Prelims cutoff average to be 100 out of 200, you only have to work for more 64 marks if well worsed with environment topic.
