What is an open-book examination? at a glance
An open-book examination, also called an open book exam, is a test in which students may consult notes, textbooks or other approved material while they answer. The questions usually ask students to apply what they know, not just recall it. The examiner decides which materials are allowed, how long the paper runs and whether it is written in a room or at home. India's education ministry listed open-book examinations as an assessment option in its PRAGYATA guidelines of 14 July 2020.
| Item | Detail |
|---|---|
| Definition | Students may use notes, textbooks or other specified resources during the test |
| What it tests | Understanding and the ability to apply what was learned, more than memory |
| Materials | Set by the examiner: own notes only, the textbook only, or wider material |
| Settings | In an exam room, remotely from home, or as a take-home paper |
| Indian official references | CBSE Open Text Based Assessment (from March 2014); PRAGYATA guidelines (14 July 2020); University of Delhi remote open-book exams (2020-21 session) |
| Rule for your school this session | Set by the school and its board; ask for the written assessment policy |

Formats of open-book exams
Open-book exams differ on two points: which materials are allowed, and where the paper is written.
On materials, this article uses two labels. A restricted exam allows only listed items, such as a prescribed textbook, a formula sheet or the student's own notes. An unrestricted exam allows any printed or handwritten resource the student brings. Massey University's study guidance says a student may be limited to their own notes or just the textbook, and that the course coordinator should say what can and cannot be used.
On setting, a paper can be written in an exam hall or somewhere else. The University of Delhi's notification of 23 April 2021 shows both in one policy. For the 2020-21 session, final-semester postgraduate students wrote open-book papers either at their faculty or department (physical mode) or from home (remote mode), depending on the option chosen in the exam form. The paper lasted four hours. Three were for answering; the fourth covered downloading the paper, scanning the answer sheets and uploading them. The university called this a one-time measure because of COVID-19.
A take-home paper goes a step further. The student receives the questions and returns the answers after a window the examiner sets, so it is completed outside the hall.
| Format | What is allowed | Where | Watch for |
|---|---|---|---|
| Restricted, in room | Only listed items | Exam hall | Know the exact list before the day |
| Unrestricted, in room | Any notes or books the student brings | Exam hall | Too much material slows you down |
| Remote, timed | Whatever the examiner permits | Student's home | Time for download, scanning and upload |
| Take-home | Whatever the examiner permits | Anywhere, within a set window | Referencing and original wording |

What Indian official sources say
One official Indian version was partial. A Press Information Bureau release of 13 August 2014 said CBSE had introduced Open Text Based Assessment from March 2014 in Summative Assessment II of Class IX (Hindi, English, Mathematics, Science and Social Science) and in the final examination of Class XI (Economics, Biology and Geography). A component of 15 to 20 percent was based on material supplied to students in advance, in the form of case studies. The stated aim was to take stress away from memory-based assessment and to test higher-order skills such as analysing, applying, inferring and problem solving.
The PRAGYATA guidelines on digital education, released on 14 July 2020 and described in the document as advisory, were prepared by NCERT. In the planning section they say that open-book examinations can be undertaken, and that quality test items for open-book assessment need to be prepared by subject specialists and assessment experts. The ministry's release carries the date.
News reports about open-book rules have not always matched board notices. CBSE's miscellaneous circulars page lists a notice dated 18 November 2024 headed as a disclaimer against news on syllabus reduction and the conduct of open-book exams in selected subjects for the Class X and XII 2025 examinations. For the 2026-27 session, read the latest notices on the CBSE academic circulars page and ask the school for its written policy.

How to prepare for an open-book exam
Prepare as you would for a closed-book exam. Massey University's guidance says open-book tests need just as much preparation, because they tend to test understanding and application rather than memory. The paper is not the place to read a topic for the first time.
Find out the rules
Ask what you may bring, how long you have, which topics are covered, how long answers should be and whether you must cite sources. Maynooth University's guide lists these same points. Ask too about technology, since Massey advises checking what can and cannot be used.
Organise and index your notes
Maynooth's guide suggests clear headings, brief and legible notes grouped by topic, numbered pages with a contents page, and bookmarks on useful chapters. Keep formulae in one separate place. Massey adds colour highlighting and mind maps for fast retrieval.
A one-page index at the front helps. Each line holds a topic, a page number and a one-line reminder, for example "Quadratic formula, page 14, check the discriminant first".
Practise application questions
Open-book questions often ask you to compare, evaluate or apply, according to Maynooth. Practise with past papers or textbook problems of that kind, and write full answers under the same time limit and conditions as the real paper, as Massey advises.
Students preparing in Hyderabad can practise multi-step problems with approved maths tutors, case-study and source-based answers with social science tutors, and structured written answers with English tutors.

Common mistakes
- Skipping revision because the answers are in the book. Maynooth's guide calls this a wrong impression, and says examiners may expect higher-quality answers because materials are available.
- Bringing too much. Massey warns that excess material wastes time and that the working space is small.
- Copying from the textbook. Massey says not to copy directly, and that plagiarism rules still apply in an open-book exam.
- Learning during the exam. There may be time to look something up, but not to learn how a formula works.
- Leaving notes unorganised, so every lookup takes minutes.
- Missing the rules on devices, references or which items are permitted.
06
What to do next
Start by asking your teacher what the format is and what is allowed. Then build the index, and spend most of your practice time on questions that need you to apply a method, not recite it.

Frequently asked questions
Is an open-book exam easier than a closed-book exam?+
Not necessarily. Massey University says open-book exams can be as difficult as closed-book ones and need as much preparation, because they test understanding and application. Having the book to hand does not replace knowing the topic.
What can I take into an open-book exam?+
Only what the examiner allows. The rule may be your own notes, a prescribed textbook, a formula sheet or wider material. Check the exact list in writing before the day.
Can I use a phone or laptop in an open-book exam?+
Only if the rules say so. Massey advises asking the course coordinator which technology is permitted. In the University of Delhi's 2020-21 remote format, devices were used to download the paper, scan answer sheets and email them.
What is the difference between an open-book exam and a take-home exam?+
An open-book exam may be written in a hall or at home within a fixed time. A take-home paper is completed outside the hall within a window the examiner sets. Both can allow notes and books.
Has CBSE used open-book exams?+
Yes, in a partial form. A PIB release of 13 August 2014 says CBSE introduced Open Text Based Assessment from March 2014, with 15 to 20 percent of marks based on material supplied in advance. For the current session, check CBSE's latest circulars and your school's policy.
How do I study for an open-book exam?+
Revise as for a normal exam, then organise and index your notes by topic with page numbers. Practise application questions under timed conditions, and keep formulae in one place.
