Topic Wise UPSC Prelims Weightage Analysis

The UPSC Prelims is the first hurdle you need to clear to embark on your journey to the coveted civil services. But with a vast syllabus and limited time, it's easy to feel overwhelmed. Understanding the UPSC prelims subject wise weightage and knowing which subjects pack the biggest punch is crucial.

Let's decode this.

The UPSC Prelims consists of two papers:

• General Studies Paper I

This paper holds the key to your final ranking. It’s worth 200 marks and comprises 100 objective-type questions. It includes a mix of history, geography, polity, economy, environment, and current affairs. You get two hours to tackle this paper, but keep in mind there’s a negative marking of 1/3rd of the marks allotted to each question.

‍

• General Studies Paper II (CSAT)

Unlike Paper I, CSAT is a qualifying paper testing your aptitude and reasoning skills.

You need to secure a minimum score to proceed to the Mains. It’s also objective-type with 80 questions in two hours, and it also carries a negative marking of 1/3rd of the marks per question.

Remember: While CSAT is important to clear, your focus should primarily be on General Studies Paper I, as it determines your rank. Understanding the UPSC prelims subject wise weightage for GS Paper I can help you prioritize your preparation effectively.
