Good lecture notes are one of the most useful study tools you can have. But many students either write down every word, or write almost nothing. Efficient notes capture the key ideas clearly, so you can review them quickly later.
This guide explains how to take efficient lecture notes in class, three popular note-taking methods, and how to use your notes for revision.
Before the Lecture
- Skim the reading or slides for 5–10 minutes.
- Write the date, topic and lecture number at the top of the page.
- Note one or two questions you want answered.
During the Lecture
- Listen for signals: “the main point is…”, “there are three reasons…”, “this will be in the exam”.
- Write key ideas, not full sentences.
- Use abbreviations and symbols: → (leads to), ↑ (increase), e.g., vs.
- Leave space to add details later.
- Mark confusing points with a question mark.
Three Note-Taking Methods
1. The Cornell Method
Divide the page into three parts: a narrow left column for key words or questions, a wide right column for notes, and a bottom section for a short summary. After class, cover the right side and use the left-column cues to test yourself.
2. Outline Method
Use headings and indented bullet points to show main ideas and supporting details. Good for well-structured lectures.
3. Mind Maps
Put the main topic in the centre and branch out with subtopics. Good for visual learners and subjects with connected ideas.
| Method | Best for |
|---|---|
| Cornell | Self-testing and revision |
| Outline | Structured lectures |
| Mind map | Connected ideas, visual learners |
Handwritten or Laptop?
Handwriting forces you to summarise, which can help understanding. Laptops are faster but tempt you to type every word and to get distracted. Choose what helps you think, and turn off notifications if you use a device.
After the Lecture
- Within 24 hours, review and tidy your notes.
- Fill gaps using the textbook or slides.
- Write a short summary at the bottom.
- Turn key points into questions and test yourself.
Self-testing from notes is powerful; UC San Diego explains retrieval practice. See also the University of Edinburgh’s summary of effective learning strategies and the US IES tips on studying effectively.

Final Thoughts
Efficient lecture notes capture key ideas, leave space for later, and become self-testing tools. Choose a method that suits you, review within 24 hours, and your notes will save you hours before exams.
