How to Practise CSAT (UPSC Prelims Paper II)

CSAT — General Studies Paper II of UPSC's Civil Services Prelims — is a qualifying paper: you need a minimum of 33% to clear it, and marks above that do not count towards the Mains cut-off or your final rank. That single fact should shape how you practise it: the goal is a comfortable, reliable pass, not a high score, so your CSAT preparation should be steady and time-efficient rather than the centre of your study plan.

What "qualifying" actually means

Under UPSC's 2026 Civil Services Examination notice, Paper II carries 200 marks, is objective type, and runs for two hours, exactly like Paper I. The pass mark is fixed at 33% — that is 66 of the 200 marks. Clearing this threshold is compulsory: you must sit both Prelims papers, and it is General Studies Paper I, not CSAT, that decides your cut-off for the Main Examination. Once you clear the 33% threshold, further CSAT marks earn you nothing extra — so treat the paper as a gate to clear comfortably, with a safety margin, rather than a subject to maximise.

The same negative-marking rule applies here as in Paper I: a wrong answer costs one-third of that question's marks, choosing more than one option counts as wrong, and leaving a question blank costs nothing. In a qualifying paper with a modest pass mark, this makes selective attempting — skipping questions you are unsure of rather than guessing blindly — a sound approach once you are close to a safe margin.

The syllabus, part by part

UPSC's notice lists CSAT's coverage as: comprehension; interpersonal skills including communication skills; logical reasoning and analytical ability; decision-making and problem-solving; general mental ability; and basic numeracy (numbers and their relations, orders of magnitude) and data interpretation (charts, graphs, tables, data sufficiency), both specified at Class X level. Here is how to practise each part.

  1. Comprehension. Read a variety of prose passages — government reports, NCERT chapters, long-form articles on public affairs — and practise answering questions that ask you to identify the main argument, an implied conclusion, or the author's tone, not just a directly stated fact. One suggested priority: try reading a passage once carefully, at a reasonable pace, rather than several times under pressure.
  1. Logical reasoning and analytical ability. The notice's own syllabus wording is simply "logical reasoning and analytical ability." As illustrative practice formats rather than an official list, this can include syllogisms, seating and sequencing puzzles, statement-and-conclusion questions, and coding-decoding, practised regularly in short sessions rather than in occasional long ones.
  1. Decision-making and problem-solving. These questions can describe a workplace or public-service situation and ask you to judge a reasonable response among several plausible ones. Practise by reading each option carefully and asking which reflects fairness, proportionality and good sense. Reasoning through the trade-offs is a useful habit alongside knowing any relevant rule.
  1. General mental ability. This overlaps with logical reasoning — practise both together rather than as separate categories.
  1. Basic numeracy and data interpretation, Class X level. Revise school-level arithmetic, percentages, ratios, averages, and simple algebra, then practise reading tables, bar charts and line graphs quickly for the specific number asked, rather than trying to absorb the whole chart. Since the notice caps this at Class X level, one suggested priority is to focus your time there rather than on more advanced material.

Building a practice rhythm

A short CSAT session most days — one example routine is thirty to forty-five minutes of a mixed set covering comprehension, reasoning and numeracy, adjustable to what you find works — keeps these skills current without eating into the wider reading that General Studies Paper I demands. As your exam date nears, add a small number of full-length, timed CSAT sets to build pacing and stamina, since two hours of sustained objective-type answering is itself a skill.

Keep the proportion right

Because CSAT is qualifying and GS Paper I is not, a regular reading habit combined with light, consistent CSAT practice is a sound way to build a safe margin over the 33% mark. If comprehension, reasoning or numeracy genuinely feel weak, address that early and directly — but resist letting CSAT preparation crowd out the wider reading that actually decides your result.
