Illustrative study example

Keep the central idea and its important limit

Source note

A choice uses scarce resources. Choosing one use means giving up another. Opportunity cost describes the value of the best alternative forgone, rather than every possible alternative added together.

Key idea

A choice has an opportunity cost: the value of its best forgone alternative.

Check your understanding

Why is opportunity cost not the sum of all the alternatives you did not choose?

Example prepared for this guide. Your result depends on your source material and should be checked against it.

From material to practice

  1. 1. Add the material

    Add a PDF to your notebook or start from a YouTube lecture link. Use one topic at a time so the result has a clear scope. Availability of source content and file readability affect what can be processed.

  2. 2. Compare notes with the source

    Read the outline alongside the original material. Check numbers, definitions and exceptions. Keep the original diagram or derivation when a short explanation would lose important detail.

  3. 3. Turn the outline into a study session

    Choose the ideas you cannot yet explain. Use questions, quizzes or flashcards to practise those parts instead of repeatedly reading the summary from beginning to end.

A summary helps you find the structure of a lecture. It does not replace the original material, a teacher's explanation or the application problems your exam may require.

Before you start

What can I start from?
Ozard supports workflows for PDFs and YouTube lecture links. This page describes those inputs; it does not promise that every external link or protected video can be processed.
Does a summary include everything in the lecture?
A summary is selective and AI may omit or misinterpret details. Keep the source available, especially for formulas, diagrams and exceptions.
What should I do after reading the summary?
Close it and answer a few questions from memory. Return to the source for missing ideas, then try a problem in the format your course assesses.
