Explore UPSC Prelims
The UPSC Civil Services Prelims is the first and most ruthless filter in the Civil Services Examination. General Studies Paper I decides who advances; CSAT is qualifying. The syllabus is deliberately broad — polity, history, geography, economy, environment, science and current affairs — which means no candidate ever finishes it, and the winners are the ones who manage attempts and elimination best.
This is why Prelims is fundamentally a test-taking skill, not only a reading skill. MockPrep UPSC mocks apply the official +2 / −0.66 marking, mix static General Studies with current affairs, and provide detailed explanations so that each wrong answer teaches you the underlying concept rather than just the correct option.
One-third of a mark lost per wrong answer sounds mild, but across 30 loose guesses it is a full 20 marks — routinely the difference between clearing and missing the cut-off.
| Section | Question type | Marks | Notes |
|---|---|---|---|
| General Studies | Objective MCQs | +2 / −0.66 | Static plus applied questions |
| Current Affairs | Objective MCQs | +2 / −0.66 | Frequently linked back to static concepts |
| Indian Polity | Objective MCQs | +2 / −0.66 | Highest-return static area |
| Geography | Objective MCQs | +2 / −0.66 | — |
| History | Objective MCQs | +2 / −0.66 | Modern India carries the most weight |
What each subject covers, and where to focus your hours first
Where to focus: The most predictable and highest-yield area. Master it first — it repays study more reliably than any other section.
Where to focus: Pair every current-affairs location with the map. Place-based questions are common and quick to secure.
Where to focus: Modern India dominates. Culture questions are unpredictable — read them once, do not over-invest.
Where to focus: Environment questions increasingly ride on current affairs. Connect every news item to its underlying concept.
Where to focus: Read one source consistently for around twelve months rather than many sources sporadically.
Sit for the full test in one uninterrupted block, with a clock running and no notes open. A mock taken in pieces tells you what you know; a mock taken under exam conditions tells you what you can actually produce on exam day, which is the only number that matters.
Prelims rarely asks what you know outright; it asks which of four statements is defensible. Train yourself to knock out options using constitutional logic, timeline sense, or the absoluteness of words like 'only' and 'never'.
Decide from your mocks how many questions you can attempt while holding accuracy near 70%. Walking into Prelims with a known attempt range removes the single biggest source of last-hour panic.
A news item is only useful when it is anchored to a constitutional provision, a scheme, or a location. Build that link during review and current affairs stops feeling infinite.
The Prelims syllabus is too large to read once and remember. Rotate through your core areas repeatedly, using the dashboard trend chart to spot which subject has decayed since your last pass.
These bands come from the same percentile model the app uses after every test. They are estimates for tracking improvement, not official cut-offs.
| Score in mock | Estimated percentile | Standing | Indicative rank band |
|---|---|---|---|
| 30% | 19.6 | Top 80% | 8,68,320 – 10,61,280 |
| 45% | 58.5 | Top 42% | 4,48,200 – 5,47,800 |
| 55% | 82.3 | Top 18% | 1,91,160 – 2,33,640 |
| 70% | 97.7 | Top 2% | 24,840 – 30,360 |
| 85% | 99.9 | Top 0.1% | 1,080 – 1,320 |
