How these tests were built

Each question in this series was drafted by an AI question-generation pipeline and then reviewed by a human before publication. The intent is to mirror the structure, difficulty distribution and topic spread of the UPSC Prelims paper — not to reproduce any specific question from a past year.

Explanations are AI-generated and shown after you submit a test. We mark every question as AI-assisted so you can calibrate how much weight to put on each explanation. If you spot an error, tell us — we read every report.

What the 10 tests cover

GS Paper I — 7 tests

Seven tests cover GS Paper I — the 200-mark paper that decides who clears Prelims. Coverage spans History (Ancient, Medieval, Modern, Art & Culture), Polity & Governance, Geography (Physical, Indian, World), Economy, Environment & Ecology, Science & Technology, and Current Affairs, in proportions that track recent Prelims papers.

CSAT Paper II — 3 tests

Three tests cover CSAT Paper II — the qualifying paper requiring 33%. Coverage includes Comprehension, Logical Reasoning, Data Interpretation, and Basic Numeracy. These are deliberately heavier on RC and reasoning than on quant, matching the recent CSAT difficulty drift.

UPSC Prelims 2026 exam date

24 May 2026 — UPSC Civil Services Preliminary Examination 2026 is scheduled for 24 May 2026 per the official UPSC examination calendar. Both GS Paper I and CSAT Paper II are written on the same day.

Syllabus coverage

A detailed test-by-test syllabus mapping for both GS Paper I and CSAT Paper II will be published with the series. Until then, the test cards above carry the subject and topic tags from the question bank.

How to use this series

Take Test 01 (GS-I) cold, in one sitting, with the timer running. Resist the urge to pause.
After submitting, read the AI explanation for every question you got wrong or guessed. Note the topic.
Space the remaining nine tests across your revision calendar — one every 3-5 days works well in the final 8 weeks.
Treat the three CSAT tests as a sanity check, not as primary prep. If you are clearing 40%+ comfortably, move on.
