Everything you need to learn UPSC CSE, open to everyone.
Six things every topic page gives you. Each card opens a real page, so you can judge for yourself.
Explained the way a topper's notes read
Definition → full explanation with a table of contents → key concepts → the comparisons the paper likes to test.
Example: ParliamentPrelims MCQs that explain the traps
10,532 Prelims questions across the UPSC library. Every option is explained — including why the wrong ones look right.
Example: Parliament · Prelims MCQsMains questions on every topic
The questions a topic can throw in GS-II or GS-III, with the demand decoded, so you practise structure before you practise speed.
Example: Judicial Review · MainsWhy it matters, for this exam
How often the topic is asked, in which paper, and the angle the examiner takes — before you decide how much time it deserves.
Example: Emergency Provisions · Why it mattersRevision in thirty seconds
1,930 revision notes — a thirty-second read and a mnemonic on every topic, for the week before the paper.
Example: Monsoon System · RevisionThe syllabus as a tree
Every chapter, topic and sub-topic of every GS subject in order, so you always know where you are and what is next.
Example: Indian Polity — full treeA week on Vyyuha, for a UPSC aspirant.

A Mains outline, a Prelims trap, the cases behind a doctrine — written out on the topic's slate.
Ask on any topic page and the mentor writes the answer the way a teacher would at the board: it decodes the demand, builds the intro–body–conclusion, cites the articles and cases, then lists what you should know first. For a Prelims question it explains the trap, not just the key.
- Mains answers built move by move, 150 or 250 words
- Prelims options explained — why each distractor looks right
- Prerequisites: the articles, cases and reports the answer depends on
- Article 368 and the amending power
- Kesavananda Bharati (1973) — the ratio, not just the name
- Minerva Mills (1980) and the balance with Part IV
- Answer structure: intro – body – counter-view – conclusion
The mentor pulls the cases, articles and answer moves a question depends on — across GS-I to GS-IV — so you fix the gap, not just this answer.

Eleven GS subjects, two stages, one timeline — and today's plan every morning.
The tracker holds every UPSC topic against the official syllabus: covered, pending, due. Give it your Prelims date and it rebuilds the plan every night around what you actually did — reading, MCQs and revision in the right proportion, CSAT checked every fortnight so the qualifying paper never surprises you.
- Covered vs pending, subject by subject, GS-I to GS-IV and CSAT
- Timeline to Prelims and Mains: days left, weekly targets, today's plan
- Pending topics linked straight to their pages
Every topic in three kinds of notes — and brought back before you forget it.
Read a topic as a textbook explains it, as a solved MCQ reasons through it, or as a revision card compresses it. The repetition engine schedules each topic to return just before it fades, tuned to your Prelims date, so the week before the paper is a glance, not a re-read.
- Full explanation · step by step · quick glance, on every topic
- Recall strength per topic; due-today queue
- Tuned to the exam date — shorter gaps as Prelims approaches
- Parliament: President + Lok Sabha (543) + Rajya Sabha (245)
- Articles 79-122 govern Parliament
- Lok Sabha: 5 years, direct election, age 25+
- Rajya Sabha: 6 years, indirect election, age 30+
- Money Bills: Only Lok Sabha, Article 110
- Joint Sessions: Article 108, Speaker presides
Each topic comes back just before you would forget it, so it stays on top of your mind.

What exactly is free?+
Every topic page in the library: the explanation, key concepts, comparisons, Prelims MCQs with all options explained, Mains questions, 'why it matters' and revision notes. No sign-up, no card.
Which parts of the syllabus are covered?+
GS-I (History, Geography, Art & Culture), GS-II (Polity, Governance, IR, Social Justice), GS-III (Economy, Environment, Science & Tech, Internal Security), GS-IV (Ethics) and CSAT — as a chapter → topic → sub-topic tree built from the official syllabus.
How is this different from a coaching PDF?+
Each page is built for one syllabus node, so it says what that node is, what it is confused with, how it is asked, and how to revise it — instead of a chapter you have to mine yourself. And it links to its neighbours, so you always know what comes next.
When do I need Premium?+
When you want the preparation managed, not just the material: a plan to the exam date, the AI Mentor on every page, live mocks with a percentile, the repetition engine and the Predictive Syllabus. It is one plan — Vyyuha — at ₹6,400 a month or ₹50,000 a year, everything included. The reading stays free either way.
