UPSC CSAT Syllabus

Class X-level maths and reasoning can still feel unpredictable when you are unsure which CSAT topics will actually appear. Many aspirants either spend too long on CSAT or ignore it until a low score puts their Prelims result at risk.

PW offers online UPSC batches with live classes, recorded lectures, mock tests and practice questions, so you can practise CSAT topics alongside General Studies. Use the topic list, exam pattern and qualifying criteria below to plan your CSAT preparation around what the paper tests.

UPSC CSAT Syllabus (Paper 2)

CSAT, short for Civil Services Aptitude Test, is General Studies Paper II of the UPSC Civil Services Preliminary Examination. It was introduced in 2011 to test the analytical skills, reasoning ability and aptitude of aspirants. The UPSC Paper 2 syllabus covers seven areas:

  • Comprehension;

  • Interpersonal skills including communication skills;

  • Logical reasoning and analytical ability;

  • Decision making and problem solving;

  • General mental ability;

  • Basic numeracy (numbers and their relations, orders of magnitude, etc.) (Class X level), Data

  • interpretation (charts, graphs, tables, data sufficiency etc. — Class X level);

Note 1: Paper-II of the Civil Services (Preliminary) Examination will be a qualifying paper with minimum qualifying marks fixed at 33%.

Note 2: The questions will be multiple-choice, objective type.

Note 3: It is mandatory for the candidate to appear in both the Papers of Civil Services (Preliminary) Examination for the purpose of evaluation. Therefore, a candidate will be disqualified in case he/she does not appear in both the papers of the Civil Services (Preliminary) Examination.

UPSC CSAT Exam Pattern

CSAT is one of the two papers in Prelims. The UPSC Prelims exam pattern for Paper II is as follows:

How to Prepare for the CSAT Syllabus?

A topic-wise routine works better than solving random papers. You can use this approach:

  • Comprehension: Read passages regularly and answer the questions using only what the passage says.

  • Basic numeracy: Revise Class X-level arithmetic, such as numbers, ratios, percentages and averages, and practise solving without a calculator.

  • Data interpretation: Practise questions based on charts, graphs, tables and data sufficiency.

  • Reasoning and decision making: Solve a few questions daily, and compare every option against the situation before choosing one.

  • Timing: In 120 minutes, you have about 1.5 minutes per question. Skip lengthy questions first and return to them later.

  • Practice: Solve previous year papers to learn the question types, then take full-length mock tests to check your accuracy under time pressure.

  • Negative marking: Review your wrong answers after every test and follow tips to reduce UPSC negative marks.

The UPSC CSAT syllabus covers comprehension, reasoning, decision making, Class X-level numeracy and data interpretation, and you need 33% to qualify. PW’s online UPSC batches, with live classes, recorded lectures, mock tests and practice questions, can support your CSAT practice.
