CSAT PYQ Test Series: Clear UPSC GS Paper II with Subject, Topic and PYQ-Wise Tests
Tests built from real UPSC CSAT questions, taken subject-wise, topic-wise or PYQ-wise, so that the qualifying paper is never the reason your Prelims attempt ends.
Find out where you stand on CSAT
One test on your weakest skill tells you more than a month of assuming you will be fine.
General Studies Paper II, known as CSAT, was introduced in 2011 and has been a qualifying paper since 2015. It has 80 questions worth 200 marks in two hours, and you must reach 33 per cent, which is 66 marks, for your GS Paper I to be evaluated at all.
Because CSAT does not add to merit, many aspirants give it little time. Every year, some of them clear the cut-off in GS Paper I and still miss the Mains because of this paper. Regular tests are the simplest insurance. This page explains the safety margin you need, maps the official syllabus to test practice, shows how to drill each skill, and sets out a plan for the whole preparation year.

Why a Qualifying Paper Needs a Safety Margin
Each CSAT question is worth 2.5 marks, and a wrong answer costs one-third of that, about 0.83 marks. That penalty is what makes the qualifying mark harder than it looks. The table shows how wrong answers eat into your margin.
| Correct | Wrong | Net marks | Result |
|---|---|---|---|
| 27 | 0 | 67.5 | Just clears |
| 30 | 10 | About 66.7 | Clears by a whisker |
| 30 | 15 | 62.5 | Does not clear |
| 40 | 10 | About 91.7 | Comfortable margin |
Two lessons follow. First, careless attempts can turn a pass into a fail. Second, a candidate who is only just clearing in practice is at real risk on exam day, when a single hard comprehension set can cost several marks. Aim to clear your practice tests comfortably, not narrowly.
Measure your margin
Take a CSAT test, work out your net marks and see how far above the line you are.
The CSAT Syllabus, Mapped to Test Practice
The official syllabus lists seven areas. Grouping them by the kind of practice they need makes your test plan clearer.
| Syllabus area | What it tests | Test habit to build |
|---|---|---|
| Comprehension | Reading a passage and inferring correctly | Answer only from the passage, not from opinion |
| Interpersonal skills including communication skills | Judging effective communication | Pick the response a fair, practical person would |
| Logical reasoning and analytical ability | Following arguments and conditions | Write the conditions down before you solve |
| Decision making and problem solving | Choosing sound actions in a situation | Eliminate extreme or rule-breaking options first |
| General mental ability | Series, patterns, arrangements | Recognise the question type within seconds |
| Basic numeracy (Class X level) | Numbers, percentages, ratios and similar | Fast, accurate arithmetic with checks |
| Data interpretation (Class X level) | Reading tables and charts | Approximate first, calculate only when needed |
Start with your weakest area
Pick the row in the table that worries you most and test it first.
Subject-Wise, Topic-Wise and PYQ-Wise CSAT Tests
The CSAT PYQ test series can be taken in three ways. For an aptitude paper, each mode has a clear job.
Topic-Wise: Drill One Question Type
Aptitude improves by repetition of one pattern until it becomes automatic. Topic-wise tests let you do exactly that, whether the weak spot is percentages, seating arrangements or a particular kind of inference question.
Subject-Wise: Balance a Whole Area
Once individual question types feel comfortable, subject-wise tests check that you can switch between them within a broad area such as reasoning or numeracy without slowing down.
PYQ-Wise: Face the Mix
The real paper mixes passages, puzzles and calculations. PYQ-wise tests move you beyond one subject or topic, which is where decisions about skipping and time allocation are practised.
Choose today's mode
Early on, stay topic-wise. Add the other modes as each skill settles.
Drilling Each CSAT Skill
Different skills improve in different ways. Plan your topic-wise tests around the way each skill actually grows.
Comprehension
Comprehension improves slowly, through regular reading and regular practice. Take a short set of passages several times a week. After each set, check every wrong answer against the passage and find the exact line that should have guided you.
Numeracy and Data Interpretation
These improve quickly with focused practice. Revise one concept, such as ratios or averages, then take a topic-wise test on it the same day. Keep a page of shortcuts and common traps.
Reasoning and Mental Ability
Most reasoning questions fall into recognisable families. Learn to name the family within seconds, then apply the method that suits it. Questions that you cannot place in a family are the ones to skip in the exam.
Decision Making and Interpersonal Skills
Look for the option that is lawful, practical and fair to all parties. Options that are extreme, evasive or that pass the problem to someone else are rarely right.
Drill one skill this week
Choose one skill, take three short tests on it and compare the first with the last.
Simulating the CSAT Paper Yourself
Two hours for 80 questions gives you about 90 seconds a question on average, but CSAT questions vary widely in length. A comprehension set can take several minutes, while a simple numeracy question may take thirty seconds. A plan for the paper matters as much as the skills.
- Keep your own clock. Set it before a test and stop when it rings, allowing roughly the same time per question as the real paper.
- Decide your order. Some candidates start with comprehension, others with numeracy. Try both in your tests and keep the order that gives you more net marks.
- Set a skip rule. If a question has not opened up within a fixed time, move on and return later.
- Do the arithmetic. After every test, work out your net marks with the one-third penalty and write down your distance from 66.
Practise your paper plan
Try a new question order in your next test and compare the result.
Logging CSAT-Specific Errors
CSAT mistakes are different from GS mistakes. Few come from not knowing a fact. Most come from process. Log each wrong or skipped question under one of these headings.
- Calculation slip. The method was right but the arithmetic was not. Add a quick check step, such as estimating the answer before calculating.
- Outside knowledge in comprehension. You chose what you believe rather than what the passage says. Reread the passage and find the supporting line.
- Hidden assumption in reasoning. You added a condition that was not given. Write conditions down exactly as stated.
- Time sink. You stayed too long on one question and rushed the rest. Tighten your skip rule.
- Careless marking. You knew the answer and marked another option. Slow down for the final check.
Turn errors into rules
Every heading in your log should end with a rule you follow in the next test.
A Year-Round CSAT Test Plan
CSAT works best as a steady thread through the year, not a burst in the final month. This plan fits around full GS preparation.
| Phase | CSAT tests | Focus |
|---|---|---|
| Start | One mixed PYQ-wise test | Find your starting level and weakest skill |
| Early months | Two or three short topic-wise tests a week | Build the weakest skill first |
| Middle months | Topic-wise plus one subject-wise test a week | Balance all areas; keep comprehension regular |
| Final months | Regular PYQ-wise tests in full exam conditions | Order, skip rule and a comfortable margin |
If your first test already clears the line comfortably, you can reduce the early load, but keep at least one test a week so the skills do not fade.
Begin with the starting test
One mixed test now sets the direction for the rest of the year.
Frequently Asked Questions
Settle it with one test
A single mixed CSAT test answers most of these questions for you.
Take Your First CSAT PYQ Test
CSAT rewards steady practice more than talent. Know your margin, drill one skill at a time, practise a paper plan and log every process error. Do that through the year, and GS Paper II becomes a paper you clear with room to spare.
