How to Take Notes in Class: Formats, Steps, and Review
Written and checked with AI using the references below. This is not human expert review.
Quick answer
Prepare before class, capture main ideas in your own words during the lecture, then review and fill gaps within a day or two after class. Within a day or two after class, fill gaps, write a summary, and self-test. This three-stage workflow turns raw notes into a real study tool.
What Good Notes Actually Do for You
Notes are not a transcript. Their job is to help you focus during class, organize what you hear, and give you something useful to study from later. According to the UNC Chapel Hill Learning Center, actively taking notes during class can help you focus and better understand main concepts, and good note-taking improves active listening, comprehension, and retention. The payoff comes in two phases: staying engaged during the lecture and having a reliable resource when exam time arrives.
Efficient, concise notes also save time. Disorganized or overly wordy notes create confusion later, and you end up re-reading material you already sat through once.
Step 1: Prepare Before Class Starts
The single biggest upgrade most students can make is showing up ready. The UNC Learning Center recommends three actions before the lecture begins.
- Preview your reading. Skim the assigned pages or chapter headings so you already know the main ideas. When the professor mentions a term you have seen, you write a quick note instead of scrambling to spell it.
- Check the syllabus. Know the topic and focus of today’s class so you can judge what is worth writing down.
- Glance at your last session’s notes. A two-minute review connects new material to what you already know, which makes the lecture easier to follow.
Also set up your page before the lecture starts. Write the class name and date at the top, and keep each course in its own section or notebook so you can find things quickly later.
Step 2: Capture the Right Things During the Lecture
Deciding what is worth writing down
You cannot write everything, and you should not try. Focus on main points rather than copying the entire presentation. The UNC Learning Center identifies several reliable signals that something is important.
- Signal phrases: Listen for “There are four main reasons,” “To sum up,” or “A major reason why.” These phrases flag key content.
- Repetition: If the professor says something more than once, write it down.
- Non-verbal cues: Pointing, gestures, or a change in speaking pace often mark important ideas.
- Opening and closing remarks: Introductions often preview main points; closing remarks often summarize them.
How to write efficiently
Use bullets and short phrases instead of full sentences. Develop a personal shorthand: “w/” for “with,” “b/c” for “because,” arrows for cause and effect. This keeps your hand and your attention moving at the same pace as the lecture. Jot down keywords, dates, and names that you can define or expand later. If something confuses you, mark it with a question mark so you remember to follow up.
For factual information (dates, formulas, definitions), the UNC Learning Center notes that transcribing more of the lecture can help with short-answer recall, but only if you study those notes within 24 hours.
For online or recorded lectures, watch the full lecture once without pausing so you practice deciding what matters. Then use the rewind feature to fill in major gaps, and note timestamps for sections you want to revisit.
Step 3: Choose a Format That Fits Your Subject
There is no single correct format. The UNC Learning Center lists five common structures. Pick one and use it consistently so your notes look the same each session and are easy to scan later.
| Format | Best for | How it works |
|---|---|---|
| Cornell Notes | Conceptual courses; synthesis tasks | Right column for notes, left column for cue questions, bottom strip for a summary |
| Outline | Lectures with clear hierarchy | Main points at top level, examples and details indented below |
| Flowchart / Concept map | Processes, sequences, cause-and-effect | Boxes and arrows show relationships and order |
| Charting method | Fact-heavy lectures (history, biology) | Columns for each key topic; facts listed underneath |
| Sentence method | Fast-moving lectures; quick coverage | One sentence per idea; helps you decide what is important on the fly |
How to set up Cornell Notes
Cornell Notes were developed in the 1950s by Walter Pauk, an education professor at Cornell University, and described in his book How to Study in College. The setup is straightforward.
- Draw a vertical line about one-third from the left edge of the page. The right section (two-thirds) is your note-taking column. The left section is your cue column.
- Leave a horizontal strip of about two inches (roughly five to seven lines) at the bottom of the page for a summary.
- During the lecture, write main ideas and paraphrased points in the right column. Avoid long sentences; use abbreviations and symbols.
- As soon as possible after class, write questions or keywords in the left cue column that correspond to your notes on the right.
- Write a brief summary of the page in the bottom strip in your own words.
- To review, cover the right column and try to answer the cue questions from memory. This turns your notes into a self-testing tool.
One honest note: research on whether Cornell Notes improve grades is mixed. A 2013 study found that students using Cornell Notes produced qualitatively better notes, but this did not lead to higher achievement scores. A 2010 Wichita State University study found the format may help when students need to synthesize and apply knowledge, while a simpler guided-notes approach worked better for basic recall. The format is a solid organizational tool, but it is not a guaranteed performance booster on its own.
Handwriting vs. Typing: An Honest Trade-off
Both the Cornell Learning Strategies Center and the UNC Learning Center cite research suggesting that handwriting notes is more effective than typing for learning and remembering conceptual material. The likely reason is that writing by hand forces you to paraphrase and condense, which is itself a form of processing. Typing is faster and lets you capture more volume, which can help with factual recall, but it also makes it easy to transcribe passively without thinking.
| Factor | Handwriting | Typing |
|---|---|---|
| Conceptual retention | Generally stronger | Generally weaker |
| Factual recall | Adequate | Can be stronger (higher volume) |
| Speed | Slower | Faster |
| Diagrams and drawings | Easy | Harder |
| Editing and searching later | Harder | Easy; can be backed up and shared |
| Distraction risk | Lower | Higher (browser, notifications) |
The UNC Learning Center also notes that individual differences in working memory affect which method works best for a given person. If you are prone to digital distraction, handwriting removes that variable entirely. If you have a disability that makes handwriting difficult, typing with a focused note-taking document (no other tabs open) is a reasonable alternative. There is no universal answer; the research points to a tendency, not a rule.
Step 4: Review Within a Day or Two
The review step is where most students lose the most value. The UNC Learning Center recommends going back to your notes ideally within a day or two after class to check for clarity and fill in missing pieces. This is also when you figure out what you did not understand and need to ask about.
During your review session, do these things in order.
- Fill gaps. Define any terms you abbreviated or left blank. Add context you remember from the lecture but did not have time to write.
- Write a summary in your own words. Do not copy your notes; restate the main ideas as if explaining them to someone else. This forces you to process the material rather than just re-read it.
- Write questions. Turn your main points into questions you could be asked on an exam. These become your self-test prompts.
- Self-test. Cover your notes and try to answer your own questions. If you cannot answer a question without looking, that is the gap to close, not a reason to re-read the whole page passively.
If your lecture is recorded, use the captions or rewind feature to verify anything you are unsure about. If a concept still does not make sense after reviewing, that is the right time to visit office hours or an academic coach, not the night before the exam.
Common Mistakes That Undermine Your Notes
Knowing what to avoid is as useful as knowing what to do. Here are the most common problems and how to fix them.
- Copying slides word for word. Slides are a prompt, not the lecture. Write what the professor says about the slide, not just what is on it.
- Writing in full sentences. This slows you down and fills your page with words instead of ideas. Switch to bullets and phrases.
- Never reviewing your notes. Notes you never look at again are just a record of attendance. The review step is where learning actually happens. Re-reading notes passively, without self-testing, gives you a false sense of knowing the material.
- Keeping notes from different classes mixed together. Use separate sections or notebooks. Searching through a jumbled notebook before an exam wastes time and adds stress.
- Waiting until the night before an exam to review. By then, the lecture is weeks old and gaps are hard to fill. Reviewing within a day or two while the material is fresh is far more efficient.

Frequently asked questions
Is it okay to record the lecture instead of taking notes?
Recording can serve as a backup, but it does not replace active note-taking. The UNC Learning Center notes that actively writing during class improves focus and comprehension in the moment. If you record, still take brief notes during the lecture and use the recording only to fill specific gaps, not as a substitute for engaging with the material.
How do I take notes when the professor talks too fast?
Use abbreviations and symbols for common words, write in bullets instead of sentences, and mark gaps with a dash or question mark so you can fill them in after class. The UNC Learning Center also suggests jotting down keywords you can define later rather than trying to capture every word. For recorded lectures, use the rewind feature after watching once through.
Should I rewrite my notes after class to make them neater?
Rewriting for neatness alone is low-value if you are just copying. The UNC Learning Center recommends using post-class time to fill gaps, write a summary in your own words, and generate self-test questions. If rewriting forces you to paraphrase and reorganize, it can help; if it is just transcription, it is mostly wasted time.
Which note format works best for STEM courses like chemistry or physics?
Flowcharts and concept maps work well for processes and reaction sequences. The charting method suits fact-heavy content like element properties. For problem-solving lectures, an outline format that separates the problem setup, steps, and result can help you follow the logic. The UNC Learning Center recommends experimenting with formats and sticking with what helps you access information quickly later.
How often should I review my notes after the initial post-class review?
The supplied evidence recommends reviewing within a day or two after class but does not specify a longer-term schedule. General educational psychology research supports returning to material at increasing intervals rather than cramming, but specific spaced repetition intervals are not covered in the available evidence for this article. Check the Study Skills hub for more on spaced practice.
