The Civil Service Examination is a form of national-level competitive examination. This examination is conducted in India to select some higher-level categories under civil services.

IAS Syllabus for Prelims

There are two papers of the UPSC prelims that we’ll discuss in detail below:

  • General Studies: 

The preliminary examination’s first test is the General Studies I. This examination is structured to measure a candidate’s general knowledge of a variety of topics, including Indian politics, geography, history, economics, science and technology, the environment and ecology, international relations, and related UPSC current events.

  • Civil Services Aptitude Test (CSAT): 

In addition to “Reading Comprehension” and the sporadic “Decision Making” questions, this UPSC Prelims syllabus for CSAT aims to evaluate the candidate’s capacity for handling “Reasoning and Analytical” problems.

For every question in prelims examination, 1/3rd of marks are deducted as negative marks.

However, the purpose of the preliminary exam is solely to select candidates for the succeeding rounds of the exam. The final rank list will not be calculated using the preliminaries’ scores. The main examination is going to have a wide range of topics if we compare it to the prelims examination. 

One of the appropriate methods to approach this examination is by solving the previous year’s question papers. The reason is when you attempt to solve a question paper; you get an idea of all the topics that you’re good at, along with the topics you need to work on.

IAS Syllabus for Mains

The UPSC mains examination consists of nine papers, of which two are qualifying papers worth 300 points each. The two qualifying papers are:

Paper-I: Any Indian Language Paper.

Is there any Syllabus for UPSC interview?

The major goal of taking personality tests is to evaluate a candidate’s general personality as well as attributes like confidence, honesty, intelligence, integrity, awareness of practical realities, and depth of conceptual understanding.

Some of the requirements for the interview round are stated below. Candidates are encouraged to work on them as it will improve their personality overall.

The personality test evaluates a candidate’s demeanour rather than their words alone. Additionally, candidates are evaluated or awarded final grades based on the questions they answered, not the ones they didn’t. Be confident and give the best possible responses to the questions you are confident about, and be honest and respectful when you have no idea or no clue what to say in response to a question.

The mindset that pushes or pulls one up the ladder of marks is what matters in the end. Never forget that the interview panel cannot assess your personality based on a question you have not answered.
