I've tried Cornell notes, mind maps, the Feynman technique, bullet journals, and at one painful point an obscure system involving four colour pens and a ruler. They all kind of worked. None of them stuck. The method I use now isn't trendy and doesn't have a name. It's just the version that finally fit how my brain actually works.
Step 1 — Capture, don't transcribe
The biggest mistake I made for years was trying to write down everything the teacher said. I'd end up with twelve pages of nicely formatted notes that I never re-read because re-reading them was exhausting.
The shift: I stopped trying to capture the lecture and started trying to capture my reactions to the lecture. What confused me. What clicked. What contradicted something I'd read. Anything I could re-read in a week and immediately remember the moment I learned it.
Step 2 — One page, one idea
I split each topic onto its own page (digital or paper, doesn't matter). At the top, the question or claim the lecture was actually answering — written in my own words. Then below it, three sections:
- What's true: the core facts. Short sentences, no fluff.
- Why it matters: the reason this concept exists or what problem it solves.
- Where I'm confused: the questions I still have, written out so I can ask them later.
That third section is the secret. It turns notes from a passive record into an active to-do list. You'll come back to a topic specifically because you wrote down what wasn't clear yet.
Step 3 — Review on day 1, day 3, day 7
Notes you don't review are notes that don't exist. After every session I do a quick five-minute scan that same night — not to memorize, just to make sure I understand what I wrote. Then I revisit on day three (skim), and again on day seven (try to recreate the page from memory on a blank sheet).
This sounds like a lot of work. It isn't. The first scan takes five minutes. Day three takes maybe ten. Day seven is the only "study" session, and by that point you already know the material — you're just confirming it.
Good notes don't capture the lesson. They become a conversation with the future version of you who's about to take an exam.
The "why" page
For every subject, I keep one extra page at the front called The Why. It's a single paragraph answering: "Why does this subject exist? What problem in the real world does it solve?" Sounds dramatic, but for things like statistics or history, this single page rescued me more than once. When you're drowning in formulas, knowing why the formula exists makes it possible to recover the formula yourself.
What I do during the actual lecture
Listen first. Write second. I now keep my pen down for the first sixty seconds of any new section, just to make sure I understand the shape of what's being said before I commit it to paper. The notes I write after listening are always shorter, sharper, and more useful than the notes I scrambled to write while still figuring out what mattered.
Tools I use (and ones I don't)
I write digital notes in plain text — no fancy app, no syncing across seven devices. The simpler the tool, the more I actually use it. For diagrams or anything visual, I use paper and photograph it into the same folder. That's the entire system.
I tried Notion. I tried Obsidian. I tried specialised study apps. All beautiful. None of them survived contact with a stressful exam week. Plain text always did.
What changed for me
My grades didn't suddenly jump. What changed was the panic level heading into exams. I used to feel like I was discovering material for the first time during exam week. Now I feel like I'm visiting old friends. That difference — between learning and re-meeting — is what good notes give you.
You won't find this system in a productivity book. That's kind of the point. The best note-taking method is the one you'll still be doing six weeks from now, not the prettiest one on a TikTok.
