- Build a deck of question-and-answer cards where every card traces to your notes and wrong or vague cards are removed.
You paste twelve pages of notes into an AI and get forty neat cards. After a week of revising, you find that card 23 says something your lecturer never said. Flashcards raise the stakes because you trust the back of the card: Algonquin College’s Student Learning Centre notes they include the answer, so it is easy to check whether you answered correctly. That only works if the answer is right.
So each card needs a way back to your notes. Anthropic’s guide on reducing hallucinations suggests having the model find a supporting quote for each claim and removing claims without one. This lesson turns that idea into a routine: a source line on every card, a sample check and a clean-up. Check whether your course allows AI tools for study material.

Before you start
- One section of your own lecture notes, with headings or slide numbers
- A place to keep cards, such as index cards or a flashcard app
- A highlighter or comment tool for marking cards

Label your notes and set the card rules
Label each part of your notes, such as “Week 3, slide 5”, so any fact can be traced, and paste one section only. Tell the AI to use only those notes, make one idea per card, keep answers short, add a source line with the label and a few exact words, and write “not in notes” instead of adding facts. A university AI hub guide suggests cards on relationships between ideas and common misconceptions.
Make 10 question-and-answer flashcards from the notes below. Use only these notes. One idea per card, answer under 25 words. Add a “Source:” line with the label and 5 to 10 exact words copied from the notes. If the notes do not cover something, write “not in notes”.
Notes:
[paste labelled notes]Example / expected result
Illustrative example; not a recorded model result.
Q: What does a control group do? A: It gets no treatment, so it can be compared with the treated group. Source: Week 2, “Experiments”: “control group gets no treatment”.
Check your result
Your notes are labelled and the prompt says: notes only, one idea per card, source line on every card.
Check a sample against your notes
Put your notes next to the cards. Check at least five cards, and always any card with a number, date, formula or name. Find each source line in your notes and compare the answer with the exact words. Mark it Keep, Fix or Remove, with a reason: not in notes, source line does not match, two ideas in one card, or too vague. A practical rule: if two of five sampled cards fail, check the whole set.
Example / expected result
Illustrative example; not a recorded model result.
Card 4 is Keep. Card 8 says “1998” but the notes give no date, so Remove. Card 12 asks “What is memory?”, which is too vague, so Fix.
Check your result
Each sampled card is marked Keep, Fix or Remove, with the note line you compared it with.
Clean the deck, then study with the answer hidden
Delete failed cards, rewrite vague ones into one specific question, and split cards that hold two ideas. Add a card for any key point that no card tests. Move the deck to index cards or your flashcard app, say each answer aloud before you flip, and mark misses. If a missed card seems wrong, check its source line first, then your textbook or lecturer.
Check your result
Every remaining card has a source line, the failed cards are gone, and you answer before you flip.
When it goes wrong
A source line can be wrong too, so it helps only if you open your notes and look. If your notes contain a mistake or gap, the cards inherit it. The AI does not know what your exam covers. Rules differ on using AI with course materials, so check yours before you paste anything.
Make it your own
Take one page of your own notes, make ten cards with source lines, check five against the notes and count how many needed a fix or removal.
