UPSC Prelims Subject-Wise Weightage 2011-2019 | IAS Prelims 2019 Marks Distribution

As we can see from the above chart, only questions from the subject Environment have shown a somewhat stable trend hovering around 15 to 18 questions most of the years except two dips in 2015 and 2018. The other subjects show wide variations every year.

For example, questions from Polity have ranged from 7 in 2016 to 22 in 2017. That is a wide variation for one year. Similarly, questions directly related to current affairs have ranged from none in 2013 to 27 three years later in 2016. Hence it is very difficult to predict the UPSC prelims weightage for different subjects. This is intentional on the part of UPSC to deter pattern-based studying as it is very difficult to deduce the dominating subject for the next exam. However, current affairs top the charts with a major portion of the question papers dedicated to it. Nevertheless, aspirants should practice previous year’s UPSC papers to check their preparedness. Also, a balanced study plan is a must to be able to beat the unpredictability of UPSC Prelims Subject wise marks weightage.
