Give each card one clear recall target
Start with the answer you want to be able to produce. If the back contains several unrelated facts, split it. A missed answer should tell you what needs practice.
Too broad: Explain HTTP caching.
More focused: What does a max-age directive specify in HTTP caching?
Answer: A maximum freshness lifetime, expressed in seconds.
The definition comes from HTTP Caching (RFC 9111).
The smaller card has a clear target. Other cards can cover revalidation, private versus shared caches, or a particular scenario. You can still ask ChatGPT to discuss the larger picture; your flashcards don’t have to reproduce the whole lesson.
Include enough context to make the answer fair
A question such as “What does it return?” depends on the conversation you just had. Weeks later, the same wording may mean very little. Name the function, subject, language, or situation the answer depends on.
Too vague: What’s the difference between them?
Clearer: In SQL, how do INNER JOIN and LEFT JOIN differ when a left-hand row has no matching right-hand row?
Answer: INNER JOIN excludes that row. LEFT JOIN keeps it, with NULL values for the right-hand columns.
You can check this behavior in the PostgreSQL join documentation.
Keep context separate from clues that give the answer away. A card that contains its own answer can become a reading exercise rather than a recall question.
Write an answer you can actually check
A concise answer makes grading easier. Put the required idea first. Add a small example or clarification underneath when it helps, but don’t require yourself to reproduce a paragraph word for word.
For a conceptual question, decide which elements count as a correct answer. For a vocabulary card, specify whether you’re practicing meaning, spelling, or using the word in a sentence. Those are different tasks.
If you keep rating a card Hard because the question is ambiguous, edit it. More repetitions of a confusing prompt won’t make it a clearer prompt.
Practice decisions as well as definitions
You can write a card that asks you to choose what to do in a specific situation. Include enough detail that the answer has a defensible reason.
Front: A SQL report must show every customer, including customers with no orders. Which join keeps those customers when Customers is the left-hand table?
Back: A LEFT JOIN to Orders. It preserves the Customers rows even when no matching order exists.
This is an illustrative example, not a substitute for testing the query. Change the scenario in a practice session to see whether you understand the rule beyond one wording.
For language learning, you might use a short sentence with a missing phrase. For interview preparation, ask for the opening of an explanation, then practice the full answer aloud outside the card.
Verify AI-generated facts before saving them
Read every draft. Compare claims with the original lesson or authoritative documentation, especially when an answer depends on a version or exception. Correct the content before making it part of your review routine.
Ask the assistant to work from material you’ve supplied and identify anything it couldn’t verify. A source link is a starting point for checking, not proof that the statement is supported.
Draft flashcards from the material we just discussed. Use one clear recall target per card, include the context needed to answer, and put the required answer first. Flag uncertain claims. Show all drafts for my approval before saving them to Retri.You can also add writing guidance to a Retri deck so the assistant has a consistent format to follow. The setup guide explains deck guidance and card management.
Let the review expose problems in the card
Attempt the answer before revealing it. Then ask whether a miss came from forgetting, misunderstanding, or a poorly written question. Those problems call for different responses: another review, another explanation, or an edit.
Research on recall practice supports making the attempt rather than relying only on rereading. Roediger and Karpicke’s 2006 study found better retention on delayed tests after retrieval practice than after repeated study. Read the study.
When the drafts look useful, ask the Retri ChatGPT plugin to save them. Start with a small batch and improve the cards as you use them. Our ChatGPT review workflow shows what to do next.
