Every question ever asked.
Every way to learn from it.
A continuously expanding exam-history intelligence system: official source identity, every available year/paper/session/shift/variant, full original academic analysis, linked learning, and synchronized print-and-digital book editions. Verified ingested records are shown separately from the vast research and ingest backlog.
Explore historical coverage
Pick an exam and year. This explorer shows where its official records should be sourced and what KARMA has actually ingested, without constructing imaginary questions.
Source universe ≠ published coverage
| Boundary | State / next acceptance |
|---|---|
| Verified original-source slice | 225 JEE Main Chemistry 2026 Session-2 QIDs, nine shifts; 222 internally QA-passed, two defect-closed, one key dispute. |
| Other exam years / subjects | Not asserted ingested. Enumerate each official available paper and key; identify missing, withdrawn, challenged, re-exam, language variants. |
| Original solution and strategy | Independent derivations, alternatives, traps, concept prerequisites, misconception tags, timing/method review and exam-format calibration per QID. |
| Historical statistics | Counts and trends only from complete verified, syllabus-mapped samples, never a claimed prediction based on nine shifts. |
| Publication | Third-party question wording/images commercial reproduction remains legally gated; original authored commentary and problems have their own QA. |
One question → its complete knowledge and learning graph
Question identity
Exam, board, year, date, session, shift, set, language, number, official QID, provisional/final keys, key-change/withdrawal, source hash, rights state and variant equivalence.Academic intelligence
Concept, subtopic, prerequisites, multiple solution paths, shortest valid path, step-by-step chemistry/physics/math checks, common mistakes, time strategy, exam-specific depth, verified difficulty and answer ambiguity.Learning feedback
Similar-question graph, adaptive tests, wrong-answer diagnostics, remediation, flashcards, revision and retrieval scheduling, VYOM teacher applications and BalaJEE learner history only with authorized identity and evidence.Try the book-to-digital twin
This is a real working original-example deep-link contract. It demonstrates how a printed QR/book locator can open the exact versioned digital explanation. It is not an official NTA question and makes no learner mastery changes.
Thermodynamics — original practice item
A hypothetical reaction has ΔH = −100 kJ mol⁻¹ and ΔS = −0.200 kJ mol⁻¹ K⁻¹. Assuming these values remain appropriate, find ΔG at 400 K.
Book ↔ QR ↔ digital continuity
A printed book is immutable after sale. Its code must resolve to the approved canonical question, the correct edition and a dated errata history. Digital updates are versioned, never silent edits to a printed answer.
Every supported book or mode is a projection of the same reviewed source
Chapter-wise, subject-wise, year-wise, topic-wise, solved, revision, workbook and bundled editions; print ISBN/MRP/size/binding/edition; QR locator and errata; POD/retail/distributor lifecycle.
PDF/ePub and interactive searchable filterable question bank, complete original solutions/video and alternate methods where authored, mocks, exams, reports and downloads with entitlement gating.
KARMA knowledge/provenance → BalaJEE authenticated learning/assessment/revision → VYOM authorized teaching/mentoring. No duplicate knowledge database; no fake progress just by scanning a page.
Completion gate: All source periods and variants enumerated with gaps explicitly visible → lawful source rights → independent QA → true digital/print synchronized SKU and reader acceptance → physical proof and fulfillment → customer order → reconciled bank settlement → recurring edition updates.
