The text and answers below are teaching examples, not the result of a live processing job.
Example source note
Before finding a median, sort the observations from smallest to largest. With an odd number of observations, take the middle value. With an even number, calculate the arithmetic mean of the two middle values.
Flashcard: recall the rule
Front: How do you find the median with an even number of observations? Back: Sort them first, then take the arithmetic mean of the two middle values.
Reveal the correct answer and explanation
B) 13. There are four observations and the middle values are 12 and 14. The median is (12 + 14) ÷ 2 = 13. Option D, 24, is the mean of all four values; it is a different measure.
Build review questions from your own source
Choose your course material
Upload a PDF, Word, PowerPoint or text document. If you use a lecture video or audio recording, questions use text extracted from the spoken content.
Set question and card counts
Enable quiz and flashcard options in the workspace. Select a count available with your plan and choose the study pack's output language.
Answer, check and try again
Give your answer before revealing the solution. Check the explanation against the source and revisit difficult concepts in your next study session.
When to use a quiz or a flashcard
Use a quiz question to apply a concept to an example. Use a flashcard to recall one definition, distinction or step. Break long explanations into small parts instead of placing an entire paragraph on one card.
Check the question too
Is the wording clear? Does the source support the answer? Could another option also be correct? Revisit the source instead of memorizing an ambiguous question. Generated questions are not official exam questions or predictions of what your exam will cover.
Frequently asked questions
Can I generate test questions from a PDF?
Yes. Text extracted from supported documents can be used to create quizzes and flashcards. For scanned files, check both the extracted text and the generated answers.
Do quiz answers include explanations?
The correct option comes with a short explanation. It is AI-generated, so verify important definitions and calculations against the source.
How many questions or flashcards can I create?
Available counts depend on your plan. See Plans for current allowances and the workspace for the values you can select.
Can I generate a quiz in another language?
Yes. Choose one of the 13 supported output languages for your study pack. Compare translated specialist terms and the meaning of each question with the source.
Choose a topic. Try before revealing the answer.
Upload your course material and prepare a review pack. Start by separating what you know from the points you need to revisit.
