Treat the PDF as evidence
A generated flashcard is a proposed study item. The PDF is the material you compare it with. Before reviewing a batch, open a short section of the source and check whether extraction preserved the wording that determines the answer. Pay particular attention to minus signs, units, numbered steps and headings. This matters even when the document looks clean. A two-column page may have a reading order problem; a scanned page may confuse similar characters. If the extracted material is unreliable, editing a few polished questions will not fix the foundation. Correct the input or choose a clearer source before continuing.
Inspect a concrete example
Consider a fictional programming note: “A recursive function calls itself. A base case returns without making another recursive call. Without a reachable stopping condition, the calls may continue until a runtime limit is reached.” These statements support more than one question, but they do not support claims about every language's stack size or error wording.
Before | Problem | After |
|---|---|---|
Explain recursion and its advantages. | Several targets; advantages are not in the passage. | What does a base case do in a recursive function? |
It returns. | An answer with no useful condition. | It returns without making another recursive call. |
Recursion always fails after 1,000 calls. | An unsupported universal number. | Remove this card unless the course names a specific runtime and limit. |
Give every question enough context
Pronouns are a frequent source of weak cards. “What happens next?” may be clear beside a diagram and meaningless in tomorrow's review queue. Replace it with the smallest context that identifies the situation: “In this recursive function, what must the base case prevent?” Do not remove conditions just to make the card shorter. If an answer depends on a protocol version, an experimental condition or an instructor's definition, put that condition in the question. A short ambiguous question is not automatically a better flashcard.
Make the answer easy to compare
The answer should begin with the part you would use to judge your recall. Put an explanation or a worked example after that, or use the card's notes for supplementary context. If three independent facts can each be right or wrong, consider three cards instead of one all-or-nothing prompt. Keep whole lists when the learning task genuinely requires recalling a list as a unit. The point is to make the assessment clear, not to enforce a mechanical word count. If you split a process, keep a separate question that checks how its parts relate when that relationship matters.
Use Deckumi's real editing loop
Choose the PDF creation method after signing in, review the available source and scope options, and wait for the generation flow to report the actual result. The public sample is a way to inspect the interaction; it is not a preview of an uploaded file's contents. In the resulting set, inspect individual cards and use the editor to repair wording, answers and cloze content. Check the source material where the flow provides it. Do not treat a ready state or automatic library persistence as proof that every sentence was fact-checked. If saving fails, keep the task result and follow the displayed retry instead of repeatedly creating a new task.
Test one card before reviewing the batch
Hide the answer and try to respond out loud or in your own words. Reveal it and compare meaning, not only whether the answer looks familiar. If you know the concept but cannot tell what the question expects, edit it now. A useful final checklist is: the source is readable; the intended section was used; the question has its context; the answer is supported; the scoring target is clear; and any important symbols or numbers have been checked. Apply that checklist to a few cards first, then continue through the batch. It is quality control for your own study material, not a promise that an AI can guarantee correctness.
