Real search results from the Calibre content library — chapter sections, MCQs, and definitions ranked by relevance.
Every kind of content, indexed.
Calibre's search is not just over MCQ titles. It is a full-text index over the entire body of every type of content the app holds — so a single keyword can pull a definition, a chapter section, and a past paper question all in one go.
Chapter sections
Every titled section of every PCTB / FBISE textbook chapter — Class 9, 10, FSc XI, FSc XII. Summary, key terms, key facts.
MCQ banks
Tens of thousands of textbook MCQs, practice MCQs, higher-difficulty MCQs, and MDCAT/ECAT specialised banks. Includes the correct option and explanation in the result.
Short + long questions
Subjective questions from every chapter with the model answer indexed — so a keyword search returns the question AND the answer in one hit.
Definitions
Every key term defined across the curriculum — biology, chemistry, physics, math, English, Islamiat. Tap to see the definition and the chapter it belongs to.
Formulas
Every formula in Calibre's Formula Hub — name, equation, variables, when to use. MDCAT and ECAT subjects covered.
Past papers
Solved past-paper items year-by-year and chapter-by-chapter. Search by topic and surface the years it appeared in.
Built for the way Pakistani students actually study.
Most study apps make you click through three menus to reach a chapter. Calibre lets you type the topic name once and jump straight to the right place — whether that is a textbook section, a definition, an MCQ from last year's paper, or a formula sheet.
- Ranked by relevance — the section that mentions the topic four times comes before the one that mentions it once.
- Scoped to your class and exam — a Pre-Eng XI student never sees Pre-Med Biology in their results.
- Bilingual stems — searches both English and Urdu terms across the content.
- Works offline for textbook content — once a chapter is downloaded, search runs on the device with no internet needed.

Three common student flows.
I forgot what something means.
Type the term — "homozygous", "alkali metal", "binomial theorem". Definition appears instantly with a tap-through to the chapter where it lives in your textbook.
I want every MCQ on a topic.
Type the topic — "kinematics", "oxidation reduction", "cell membrane". Every MCQ ever asked on it across textbook + past paper banks appears, ranked by how closely they match.
I am revising a chapter.
Type a key sub-topic from the chapter — "electron transport chain", "Newton third law". The chapter section, related definitions, and a curated set of practice MCQs surface together.
One search box. Your entire syllabus.
Open Calibre, tap the Search tab, and type any keyword. Watch your textbook open itself.
