Look at your notes from last term. Are they a neat copy of what the teacher said, with headings and highlighter? They probably look impressive. They may also be almost useless for studying, because they were made to be read, and reading is the weakest way to learn. Better notes are made to be tested. They give you questions to answer, not paragraphs to re-read.
This guide shows how to take notes that work as a self-test, how AI can help once you have them, and what to do in the ten minutes after a lesson. The short answer is to write in your own words, add a question for each chunk of notes, and study by covering the answers and trying to recall them.
Why do notes still matter when AI can summarise anything?
It is tempting to skip note-taking when a tool can summarise a whole chapter in seconds. But a summary you did not make does not do the same work in your head. Writing notes forces you to decide what matters, put it in your own words and notice what you do not understand, and that is where much of the learning happens. AI is useful later, for turning your notes into questions and for checking them, but it is not a replacement for making them.
The problem with copying is similar. Copying the slides or the board word for word feels productive, but you can copy a sentence without understanding it, and when you re-read it later it feels familiar, which you mistake for knowing. Familiarity is not recall, and exams test recall.
What is the questions-in-the-margin method?
One of the most effective changes you can make is a two-column layout. The right column, about two-thirds of the page, holds your notes in your own words during the lesson or reading. The left column, about one-third, is filled in afterwards, when you write a question for each chunk of notes that the chunk answers.
To study, cover the right column and answer the questions in the left, then uncover to check. You now have a self-test that you made yourself, and making the questions was itself a form of learning. Here is an example from a biology unit on cell division.
| Question | Notes |
|---|---|
| What is the purpose of mitosis? | Growth and repair: one cell divides into two genetically identical cells |
| What are the stages, in order? | Prophase, metaphase, anaphase, telophase |
| Why does the cell cycle have checkpoints? | To catch DNA damage before the cell divides |
Are there other formats that work?
Several. Cornell-style notes are similar to the two-column method, with a summary box at the bottom of the page. Concept maps, in which you draw the links between ideas, suit subjects where things connect, such as history and biology. For maths and science, worked-example notes work well: copy a problem, solve it, write what each step is for, and then make a similar problem with different numbers. Flashcards made after class from your own notes, one idea per card, turn the same material into something you can review in minutes.
How do you make notes easy to test?
Use your own words, because if you cannot, you have not understood the idea yet, and a mark in the margin tells you to ask. Keep the notes short, since notes that are too long will not be re-read or reviewed. Write questions as well as facts, and ask yourself what an exam would ask about this. Leave space, because you will want to add corrections and examples later, and flag anything that confused you, since a question mark in the margin is a note to ask a teacher. Finally, include one example for each idea. An idea without an example is easy to forget, and an example gives you something to reason from when the exam wording changes.
How can AI help with your own notes?
Once you have your own notes, AI becomes a strong assistant. It can turn them into questions, find the gaps, and check that they are right. Each of these works best with a specific prompt.
To turn notes into questions, try this.
Here are my notes on [topic]. Write ten questions that test whether I understand them, ranging from recall to application. Do not answer them. Ask them one at a time.
To find gaps, compare your notes with a syllabus outline.
Compare my notes with the syllabus outline below. What important points am I missing? List them only. Do not explain yet.
To check accuracy, ask the AI to find mistakes and quote the line.
Read my notes and tell me if anything is wrong or unclear. Quote the line.
Then check the AI against your textbook. It can be wrong, and it may pick what it thinks is important, not what your exam covers.
What should you avoid?
Do not ask AI to write your notes and then study them. It saves time and costs learning, because the effort you skipped was the useful part. Do not paste a whole textbook and ask for "everything I need to know," since you will get a polished summary and a false sense of confidence. And do not rely on highlighting and re-reading as your main study method. It feels good and does very little.
What does a good ten-minute routine after class look like?
Do this the same day, while the lesson is fresh. In the first three minutes, read through your notes and fix anything unclear. In the next four, write questions in the margin for each chunk. Then spend two minutes covering the notes and answering two or three questions from memory, and use the last minute to mark what you missed for next time. Ten minutes now saves an hour of confused re-reading before the exam.
How do you review over time?
Come back to your questions after a day, then after three days, then after a week. Each time, start with the ones you missed before. Add new questions as you learn more, and delete the ones that have become easy. Over a few weeks your list becomes a compact, personal record of what you find hard, which is exactly what you want to study before a test.
Frequently asked questions
Should I take notes by hand or on a laptop? Whichever lets you write in your own words. Typing makes it easy to copy word for word, so if you type, make a deliberate effort to rephrase.
How many questions should I write? One for each chunk of notes, usually a handful per page. If you cannot think of a question, the chunk may be too vague.
Can I just use flashcards instead? Flashcards work well for facts. Margin questions suit ideas and explanations, and it is common to use both.
What if my teacher gives us notes? Turn them into your own by adding questions and rewriting key parts in your own words. Reading someone else's notes is still reading.
