How to Take Effective Study Notes

Why note-taking matters

Effective note-taking is foundational to academic success. Good notes enable you to engage actively with lectures and reading material, consolidate understanding in your own words, build a resource that can be used for revision and essay writing, and reduce the time spent re-reading entire books or re-watching recordings.

Poor note-taking, copying everything verbatim, highlighting without processing, or taking no notes at all, leaves students with either an unmanageable volume of unprocessed material or nothing useful to return to. The techniques below help you take notes that are both efficient and genuinely useful. If you need support with essay writing, GradeQuill's essay writing service is available at all academic levels.

The Cornell method

The Cornell note-taking system divides the page into three sections: a main notes area on the right (approximately two-thirds of the page width) where notes are taken during the lecture or reading; a cue column on the left (approximately one-third) where key questions, terms, or headings are added afterwards; and a summary section at the bottom where you write a two to three sentence summary of the page in your own words.

The cue column and summary section are the most important elements, they require you to process and synthesise what you have noted, which consolidates understanding far more effectively than simply recording information.

Note-taking from lectures

The goal of lecture note-taking is not to transcribe everything the lecturer says, it is to capture the key ideas, examples, and connections in a form you can understand and use later. Focus on main points, headings, and examples rather than trying to record every word.

If your institution records lectures, use the recording to fill gaps after the session, but do not use the availability of recordings as a reason not to take notes during the lecture itself. The act of note-taking during the lecture promotes active engagement and understanding that listening alone does not.

Note-taking from reading

Before reading a chapter or article, skim the headings, abstract, and conclusion to understand the overall structure and argument. This gives you a framework for the detail you are about to read. Then read actively, pausing at the end of each section to note the main point in your own words before moving on.

Avoid highlighting as a primary note-taking strategy, it requires no processing and produces notes that are difficult to use later. Instead, write marginal notes or, better, transfer key ideas into a separate notebook or document in your own words. This paraphrasing practice also reduces plagiarism risk when it comes to essay writing. For guidance on paraphrasing, read our article on how to paraphrase.

Organising your notes

Unorganised notes are difficult to use for revision or essay writing. Develop a consistent system from the start of the academic year: organise notes by module, then by topic or week. Use clear headings and date your notes so you can locate specific material quickly.

Digital note-taking apps such as Notion, OneNote, or Obsidian offer powerful organisation tools, including the ability to link notes across topics and search full-text. However, research suggests that handwritten notes may produce better conceptual understanding for some learners, particularly during initial note-taking from lectures, because the relative slowness of handwriting requires greater selectivity and processing.

Reviewing and consolidating notes

The most important, and most neglected, aspect of note-taking is reviewing notes shortly after they are taken. Research on the "forgetting curve" (Ebbinghaus, 1885) demonstrates that memory of new material deteriorates rapidly within the first 24 hours without review. A ten-minute review of lecture notes within 24 hours of the session can dramatically improve long-term retention.

As the term progresses, consolidate notes from individual lectures into thematic summaries that integrate material across sessions. These consolidated summaries become your primary revision resource at assessment time. For guidance on effective revision techniques, read our article on how to revise for exams.
