How to turn lecture slides into study notes
To turn lecture slides into study notes, go through the deck one idea at a time and write each idea out in full sentences, adding the explanation the lecturer gave out loud and the matching part of the reading. Keep the formulas and diagrams, cut repeated bullets, and finish with a half page of must-knows.
Why slides alone are not enough
Slides are prompts for the lecturer, not a record of the lecture. A bullet like "Le Chatelier: system opposes change" makes sense in the room and means little three weeks later. Study notes fill in what the bullet stood for, so you can learn from them without the slides open.
The method, step by step
- Gather the week. The slide deck, the assigned reading, and the lecture recording or your own notes from class.
- Find the structure. Most decks cover three to six main ideas. Write those as headings before you write anything else.
- Explain each idea in full sentences. Say what it is, why it is true, and when it applies. If you can't explain a bullet, that is the part to look up in the reading.
- Add what was said out loud. Examples, warnings ("this is where people lose marks"), and anything the lecturer repeated.
- Keep the formulas and diagrams, with every symbol defined and the units named.
- Work one example per idea. A solved problem, a case, or an applied scenario, depending on the subject.
- Link to earlier weeks. Note where this week builds on an idea from before. Exams love those connections.
- Write the must-knows. Half a page of the definitions, formulas and claims you would need on a closed-book test.
Notes look different by subject
- Engineering and physics: derivations with each step justified, units checked, and a worked problem.
- Biology and health: pathways in order, with a labelled diagram and the clinical or real-world link.
- Business and finance: the formula, the intuition behind it, and the numbers worked for a case.
- Humanities and social sciences: each argument with who made it, the evidence, and the main criticism.
- Law: facts, issue, holding and reasoning for each case.
Using AI to do the first draft
An AI model can do steps 2 to 8 in a few minutes if you give it more than the slides. Upload the deck together with the reading or the recording, and ask for notes that explain every slide in full sentences, with formulas rendered and an example per idea. Then read the notes against the slides and fix anything that doesn't match how your lecturer taught it.
The draft gets better when the AI has the rest of the course too. With earlier weeks and the syllabus, it can link back to previous topics and flag what the exam covers. That is what Sendy Study Tool does with each week you upload. The wider approach is in how to study with AI using your own course material.
Turn the notes into practice
Notes are the starting point. Recall is what makes them stick, so turn the must-knows into flashcards and the main ideas into questions. How to make a practice test from your course notes covers the next step.
Questions students ask
Should I copy my lecture slides word for word?
No. Copying slides word for word takes time and teaches little. Rewrite each idea in your own words, add the explanation the lecturer gave out loud, and keep the formulas and diagrams the slides got right.
How long should study notes for one lecture be?
Long enough to explain every idea on the slides without the slides open. For a typical one-hour lecture that is often two to four pages, plus a half page of must-knows you can review the night before the exam.
Can AI make study notes from PowerPoint slides?
Yes. Upload the .pptx or a PDF export and ask for notes that explain each slide. The result is much better when you also give it the reading or the recording, because slides leave out most of the explanation.
