A PCS Prelims mock test for the UPPSC PCS 2026 cycle should copy the real paper: General Studies Paper I with 150 questions for 200 marks and negative marking of one-third of a question’s marks for each wrong answer, plus a CSAT paper in which you need 33%. Start with the official PCS Pre. Examination-2025 papers from the Uttar Pradesh Public Service Commission (UPPSC), Prayagraj, then add timed mocks.
Updated: 25 October 2026 (PCS 2026 cycle). What’s new: the mock plan follows the PCS 2026 scheme, and the official PCS-2025 papers are added as the first practice set.
Quick Answer
A good PCS Prelims mock test matches the UPPSC pattern: GS Paper I with 150 questions for 200 marks and one-third negative marking, and a CSAT paper needing 33%. Begin with the official PCS Pre. Examination-2025 papers on uppsc.up.nic.in, then take timed mocks and review every error.
What should a PCS Prelims mock test look like?
A PCS Prelims mock test is useful only when it follows the official scheme. Check any mock against this table.
| Paper | Official rule | What your mock should do |
|---|---|---|
| GS Paper I | 150 questions, 200 marks | Use the same number of questions and marks |
| Negative marking | One-third of a question’s marks per wrong answer | Apply the same deduction when scoring |
| GS Paper II (CSAT) | Qualifying; 33% needed | Score it separately against 33% |
Prelims is the first of three stages: Preliminary Examination, Main Examination and Interview. See the full scheme on our UPPSC PCS exam pattern page.
Which official papers should you use first?
The official PCS papers are the closest thing to the real exam, so take them as your first mocks. UPPSC lists them on its Previous Question Papers page.

How do you take a PCS Prelims mock test the right way?
A mock test helps only when you sit it like the real exam. Follow this sequence every time.
- Sit the paper in one go, with a timer and no notes.
- Mark guesses with a symbol so you can check them later.
- Score the paper with the official negative marking.
- Write every error in a log with its subject and reason.
- Revise the weak topic before the next mock.
How do you handle negative marking in mocks?
Negative marking takes away one-third of a question’s marks for each wrong answer, so use mocks to learn when to attempt.
- Sure answers: attempt.
- Partly sure, with options ruled out: note them as guesses and check how many come out right over several mocks.
- No idea: leave them.
Exam Tip
Keep a running count of your marked guesses and how many were right. That count, not a feeling, should decide how many partly sure questions you attempt.
How should you practise CSAT?
CSAT is qualifying, and you need 33%, so give it its own timed practice instead of skipping it. Take one CSAT mock early to find your level, then keep regular short sets and note which question types slow you down.
Topic tests or full-length mocks?
Topic tests suit the learning phase, and full-length mocks suit the final phase. Use this decision table.
| If you are | Do this |
|---|---|
| A beginner | Solve one official PCS Pre paper to see the level, then take topic tests |
| A working aspirant | Take short topic tests on weekdays and a full mock at the weekend |
| A repeater who has finished the syllabus | Move to full-length mocks under strict timing |
| Weak in Uttar Pradesh topics | Add topic tests on UP history, geography and schemes |
For UP topics, use our UP GK notes, and see our test series page for timed sets.
