Questions grounded in your material
Practise the concepts contained in the PDF rather than working through a generic question bank.
PDF study tools
Turn your PDF into a practice quiz
A file can feel familiar after several readings without being retrievable in an exam. Import your PDF into BrainDen, organize the material, and use practice questions to find what you know and what still needs attention.
Free to start No card required Your material stays connected
Immediate feedback
Check an answer and use the explanation to understand why it works before continuing.
One connected study loop
Move between the quiz, structured note, and attached source without rebuilding the material elsewhere.
From source to active study
How BrainDen turns a PDF into a practice quiz
- 01
Import the material
Choose the PDF for the topic, lecture, or reading you want to test.
- 02
Check the organized note
Review the extracted concepts and add anything important from class before you begin testing.
- 03
Answer before you reveal
Take the quiz without looking at the note, then use feedback and the original material to repair gaps.
A concrete example
Example: an introductory economics chapter
A chapter covering opportunity cost, supply, demand, equilibrium, and elasticity.
A useful result could include
- Scenario questions that distinguish movement along a curve from a shift
- Concept checks about scarcity and opportunity cost
- Feedback explaining why an elasticity calculation or interpretation is correct
Generated material is a study aid. Review important terminology, notation, and claims against your source.
Make the result better
Use AI as the beginning of your study process
BrainDen removes repetitive setup work. Your judgement, course context, and retrieval practice are what turn the result into learning.
Test before you feel ready
An early quiz is diagnostic. It shows which parts of the PDF deserve focused reading instead of another complete pass.
Explain wrong answers
After reading the feedback, state the correct reasoning in your own words so the correction becomes active.
Return later
A second attempt after a delay is a better test of retention than immediately repeating the same material.
Questions and answers
Frequently asked questions
Can BrainDen create quiz questions from lecture slides?
Yes. If the slides are in a PDF, import them to create a structured note and open the connected quiz study tool.
Do I receive feedback on my answers?
The quiz experience provides answer feedback and explanation so you can use an incorrect response to revisit the underlying idea.
Should I read the PDF or take the quiz first?
For a new topic, quickly inspect the structure first. For revision, taking a quiz before rereading can reveal the exact concepts that need attention.
Can I use other study tools with the same PDF?
Yes. The same BrainDen note can support flashcards, a mind map, highlighting and comments, translation, and Explain It Back practice.
