The UPSC CSE Prelims is an objective, two-paper test where speed, accuracy and the judgement to skip a doubtful question matter as much as knowledge. Regular UPSC CSE mock tests help you build that judgement before the Prelims, which the Commission's annual calendar schedules for 23 May 2027. This page explains which tests to take, when to take them and how to learn from every attempt.
Dates can change, so confirm them on upsc.gov.in.
UPSC Prelims Pattern to Practise In
Paper | Questions | Marks | Time | Negative marking |
|---|---|---|---|---|
General Studies Paper I | 100 (recent years) | 200 | 2 hours | One-third of the question's marks |
General Studies Paper II (CSAT) | 80 (recent years) | 200 | 2 hours | One-third of the question's marks |
The notice does not print question counts, so the numbers above follow recent papers. Both papers are held on the same day, so practise sitting two tests back to back.
Types of UPSC CSE Mock Tests
Test type | What it covers | When to take it |
|---|---|---|
Topic-wise test | One subject, such as polity, geography or economy | Right after you finish a subject |
Full-length GS Paper I | All seven areas in two hours | Once the first revision is done |
CSAT set | Comprehension, reasoning and numeracy | Every week, alongside General Studies |
Current affairs test | Events of the month | At the end of each month |
How to Use Mock Tests
Early phase: Take a topic-wise test after each subject, so gaps show up while there is still time to fix them.
Middle phase: Add one full-length General Studies Paper I a week and short CSAT sets. Keep to the two-hour limit.
Final phase: Take full-length tests in both papers, ideally at the same time of day as the real sessions, and revise only from your error log.
How to Analyse a Mock Test
A mock is useful only if you review it the same day. Sort every lost mark into one of three causes:
Concept gap: You did not know the topic, so it goes back into your notes.
Misread or careless error: You knew the answer but marked it wrongly, which is a habit to correct.
Skipped but solvable: You left a question that you could have answered with elimination or more time.
Track your accuracy, not just your score. A wrong answer in Paper I costs 0.66 marks, so guess only when you can remove at least two options. In CSAT, aim for a clear margin above the 66 marks needed to qualify.
For timed practice in the Prelims pattern, you can attempt UPSC CSE online tests on Testkart and use the section-wise analysis to plan your revision. Pair them with previous year papers to understand the real difficulty level. If you are still building your base.
