Read with purpose before you annotate

Why should you preview a chapter before you read it closely?

Previewing gives your brain a map before you dive into details. It helps you decide what matters and what you can skim. According to the University of Edinburgh's Academic Skills website, making notes should be a deliberate process that puts you in control of your learning (https://www.ed.ac.uk/institute-academic-development/study-hub/learning-resources/reading). By scanning headings, figures, and summary questions first, you create mental hooks for new information. This is not about saving time. It is about reading with a purpose.

A preview also reduces the urge to highlight everything. When you know the chapter's structure, you can separate core ideas from examples and evidence. You will still read closely, but you will do it with clear targets.

How do you preview a chapter in five minutes?

Start with the title and any learning objectives. Read the introduction and conclusion. Skim all headings and subheadings. Look at any tables, graphs, or images and read their captions. Finally, turn each heading into a question. Write those questions in your notebook. This gives you a purpose for each section. The University of British Columbia's Learning Commons advises students to read effectively by adjusting their approach to the purpose of the reading (https://learningcommons.ubc.ca/reading-effectively/). A five minute preview is that adjustment.

What does a reading purpose actually look like?

A reading purpose is a short statement of what you want to get from the text. It should be specific. For example: "I need to explain how photosynthesis converts light energy into chemical energy." Or: "I need to compare two theories of memory and find evidence for each." Write it at the top of your page. Then, when you annotate, you can ask: does this detail help me meet my purpose? If not, skip it.

Your purpose can change as you read. That is fine. Update it. The goal is to keep your attention on what you need, not on what is merely interesting.

Which questions should you write before you highlight?

Write questions that require explanation or comparison, not just recall. Good examples include: Why does this process happen? How does this concept relate to the previous chapter? What evidence supports this claim? What would happen if this condition changed? These questions turn passive reading into active inquiry. The University of Edinburgh notes that note-making can help you take control of your learning when you think about the process (https://www.ed.ac.uk/institute-academic-development/study-hub/learning-resources/reading). Your questions are the engine of that process.

How do you annotate with those questions in mind?

Annotate only when you find an answer to one of your questions. Use a small set of marks. Underline key terms. Put a star next to evidence. Write a brief margin note that summarises the answer in your own words. If a paragraph does not answer any of your questions, leave it alone. This keeps your annotations meaningful.

After each section, close the book and try to answer your question aloud or in writing. This is retrieval practice, and it strengthens memory far more than rereading. If you cannot answer, go back and find the missing piece. Then add it to your notes.

What should you do after reading the chapter?

Review your questions and answers. Write a short summary in your own words. Then link the chapter to your broader course. How does it connect to previous topics? What questions remain? Finally, schedule a quick review session in a few days. Spaced repetition will help you retain what you learned. For a deeper look at how spacing works, see our guide on spaced repetition basics at /memory-and-retention/spaced-repetition-basics/.

Comparison table: highlighting vs purpose driven annotation

Feature	Highlighting only	Purpose driven annotation
Before reading	No preview	Preview and write questions
During reading	Mark almost everything	Mark only answers to your questions
After reading	Close the book	Summarise and self test
Effect on memory	Often passive	Active and durable
Time cost	Low upfront, high later	Higher upfront, lower later

Decision checklist for your next reading session

Use this checklist before you open the book.

• I have previewed the chapter headings and summary.
• I have written at least three questions in my notebook.
• I have stated my reading purpose in one sentence.
• I have my annotation key ready (for example: underline terms, star evidence, margin notes).
• I will pause after each section to answer my questions.
• I will write a short summary after finishing.
• I will schedule a review session within three days.

If you cannot tick all boxes, take two more minutes to prepare. That small investment pays off. For more on structuring notes so they are useful later, see our article on the Cornell note method at /reading-and-notes/cornell-note-method/. If you struggle with a difficult passage, our guide at /reading-and-notes/reading-difficult-passages/ offers practical steps.

When should you seek further guidance?

If you consistently find that previewing and questioning do not help, or if reading causes significant anxiety or confusion, consider speaking with a study adviser or academic skills consultant. They can help you adapt these techniques to your subject and learning style. The University of Edinburgh, for example, offers one to one appointments with academic skills consultants (https://www.ed.ac.uk/institute-academic-development/study-hub/learning-resources/reading). Always check your own institution's current support services, as availability may change.

This method is not a prescription. It is a flexible framework. Adjust the number of questions, the length of your preview, and your annotation marks to fit your needs. The key is to read with intention, not just to cover pages.
