How to study for an open-book exam

An economics exam allows the textbook, class notes, and one page of formulas. The first question presents a new policy scenario. Finding the definition takes seconds; deciding which model applies is the real work, and the clock keeps running while the pages turn.

An open-book exam gives you access to specified sources. It does not turn the exam into a search task. The useful preparation is a combination of knowledge you can use without help, practice with the kinds of decisions the exam requires, and a reference system for the details that are worth checking.

Start with the actual exam rules

“Open book” can describe very different exams. One professor may allow a printed textbook and handwritten notes. Another may allow digital course files but no internet access. A take-home exam may provide several hours or several days while restricting collaboration, outside sources, or AI tools.

Read the instructions and write down:

• which materials are allowed;
• whether those materials may be printed, digital, or both;
• whether internet access, search, calculators, or other tools are permitted;
• the time limit and number of questions;
• the question formats and point values;
• any citation, collaboration, or AI rules stated for the exam.

These details determine the study plan. A paper-only test may call for approved tabs and page references. A timed online exam may require a small set of files that can be searched quickly. A course that grades case analysis needs different practice from one that asks for calculations or short definitions.

Learn the core material before building the reference system

The main advantage of knowing the material is speed. Familiar concepts, procedures, and relationships can be used immediately, while a source can confirm a date, formula, exception, or exact term.

One laboratory study helps clarify the role of access to notes. Participants studied prose passages, then restudied them or completed an open- or closed-book test. Both kinds of testing improved delayed retention when feedback was provided, compared with restudying. Access to the material improved performance on the initial open-book test, but open- and closed-book testing produced similar retention on the delayed test. (Agarwal and colleagues, 2008)

That study tested learning from prose passages, not performance in every college course or every open-book exam. Its useful lesson is narrower: looking at the source can help with the answer in front of you, while answering questions and receiving feedback can support later learning. Source access does not make preparation unnecessary.

Broader evidence does not show that one format is uniformly better. A 2016 systematic review found insufficient evidence to prefer open- or closed-book exams and reported that open-book exams tended to take longer. A 2025 meta-analysis likewise found no statistically significant overall difference between the formats in later learning, although results varied with factors including the retention interval. (Durning and colleagues, 2016; Permzadian and Cho, 2025)

Begin with a small set of representative questions from each major unit. Answer with the notes closed, then check each response against the course material. Sort the results into three groups:

• Ready to use: The answer is accurate and the reasoning is clear.
• Needs practice: The topic is familiar, but a step, distinction, or application breaks down.
• Needs a reference: The concept is understood, but an exact detail is hard to retain or easy to confuse.

Study the missing explanation before retrying a topic in the second group. Put only genuinely useful lookup details from the third group into the reference system. If the answer feels familiar until the notes close, the blurting method provides a simple way to expose what is missing.

Build a map, not another set of complete notes

A reference system should tell you where an answer lives. Copying the entire course into a new document creates more material to search and takes time away from practice. A separate study-guide workflow can help organize and practice a larger body of material; the open-book reference map should remain smaller and faster.

For each unit, make a compact map with entries such as:

• topic or decision;
• source name;
• page, section, note title, or heading;
• a short reminder of what is there.

An entry might read: “Choosing a statistical test — Unit 6 note, ‘Decision tree,’ under assumptions.” Another might point to the page containing a tax-rate table or the worked example for a particular equation.

Match the map to the format allowed in the exam. Add removable tabs to a printed book, number printed notes, or use clear filenames and headings in approved digital materials. Test every important route before exam day. A reference that seemed obvious while building the map may be surprisingly difficult to find a week later.

Practice the work the exam will grade

Open-book exams do not all use higher-order questions, so do not guess that every definition will disappear. Use the syllabus, review guide, past questions, sample exam, rubric, and the instructor's description to identify the work that is likely to matter.

Turn that evidence into practice:

• For a case-based exam, identify the relevant concept, apply it to new facts, and justify the conclusion.
• For a quantitative exam, choose the method before looking at the formula, then complete the calculation and interpret the result.
• For an essay exam, make a claim, select course evidence, and explain how the evidence supports the claim.
• For a short-answer exam, write complete responses within the expected length instead of collecting longer notes.

Complete some practice with the materials available, because using a reference efficiently is part of the exam. Complete other questions with the materials closed, because that reveals whether every answer still depends on searching.

When a practice answer is wrong, identify the cause. Missing knowledge calls for another explanation or worked example. A wrong method calls for practice choosing among similar methods. A slow lookup calls for a better reference entry. The correction should match the failure.

Rehearse with the real time limit

A reference system that works without a clock may fail during the exam. Complete a representative set under the actual or estimated question budget, using only the materials that will be allowed.

Track three times separately:

1. reading and planning the answer;
2. finding a detail in the permitted source;
3. writing, calculating, or revising the response.

This shows whether searching is the problem or whether the answer itself needs more practice. It also gives you a practical lookup rule. If a five-point question has a six-minute budget, spending four minutes searching for one detail is a poor trade. If backtracking is allowed, mark the question and return after higher-value work is complete; otherwise, give the best supported response the remaining budget permits.

There is no universal number of seconds for a lookup. Base the decision on the question's value, the remaining time, and whether the missing detail changes the answer.

Use the materials deliberately during the exam

If the exam format lets you view and revisit questions, start by scanning the paper or question list. Note the point values, required sections, and prompts that need source checking, then answer questions that can be completed accurately without a lookup. If the interface does not allow backtracking, budget from the information shown and move forward under its rules.

Use the permitted materials for a defined purpose: confirm a formula, locate a case, check an exception, or find evidence for a claim. Searching “the chapter about this topic” is a sign that the reference map is too broad or the underlying concept is not yet clear.

Follow the wording of each prompt. “Define,” “calculate,” “compare,” and “evaluate” require different answers. A copied paragraph may contain accurate information and still fail to perform the requested task.

Leave time for a final check that matches the risks of the exam. Verify units and signs in calculations, confirm that every part of a multi-part prompt was answered, and check that quotations or citations follow the stated requirements.

Use Bananote to prepare the source and practice

Bananote can keep the preparation work connected to the course material. Add a professor-provided PDF, paste text, scan a printed page with Scan Text on iPhone or iPad, use a YouTube link, upload lecture audio, or start from an existing note. Check names, formulas, dates, and course-specific wording against the original source before using the note for study.

Use clear titles and folders so a search returns the right unit or topic. If digital Bananote access is not explicitly permitted during the exam, treat the app as a preparation tool and build the paper or digital reference system the rules allow.

For each important note:

1. Generate a short quiz or a set of flashcards.
2. Answer with the note closed.
3. Check the response against the original course source.
4. Add only the hard-to-recall detail or source location to the reference map.
5. Practice a new question that requires using the idea, not merely finding it.

AI chat can help create application questions from one note. A bounded prompt is more useful than a request for a general exam prediction:

> Use only this note. Write one new scenario that requires choosing between the concepts it covers. Ask me which concept applies and why, wait for my answer, then identify what the note supports, what I omitted, and what I contradicted. Do not predict what will appear on the exam.

The generated question and feedback still need review when the course depends on technical or professor-specific details.

Adjust the plan for a take-home exam

A longer window changes the scheduling problem, but the exam instructions still define the work. Break the available time into reading, planning, drafting, source checking, and revision. Give each question a limit based on its point value or word count so one response does not consume the entire window.

Keep a simple source list while writing. This makes it easier to cite accurately and prevents a final scramble to reconstruct where a claim came from. Follow the course's stated rules for collaboration, outside sources, and AI rather than assuming that “take home” means unrestricted.

Frequently asked questions

Are open-book exams easier?

The format alone does not answer that question. Access to sources can help with exact details, but difficulty also depends on the questions, grading, time limit, and permitted materials. Plan from the actual exam design instead of assuming that open book means easier or harder.

Do I need to memorize material for an open-book exam?

Learn the core concepts, procedures, and relationships well enough to use them without searching. Keep exact details that are difficult to retain and useful to verify in a fast reference system.

How should I organize notes for an open-book exam?

Create a compact map that connects each topic or decision to a page, section, heading, or note title. Match it to the permitted format, then test it during timed practice.

How do I avoid running out of time?

Practice with a question budget and track how long reading, searching, and answering take. During the exam, use sources for specific details, mark searches that exceed the question's value, and finish higher-value work before returning.

Can I use Bananote during an open-book exam?

Only if the exam rules permit that kind of digital tool and access. Bananote can still support preparation by organizing verified source notes, generating practice, and helping build the reference map you are allowed to bring.
