How to make flashcards from lecture notes: a worked example

A practical workflow for choosing a short passage, checking generated questions, editing weak cards and beginning a real review.

Start with one learning question

A lecture note is a record of what happened in class. A flashcard is a question you can attempt without looking at that record. Converting every sentence into a card often produces an impressive list with no clear way to judge an answer. Start by writing what you want to be able to recall or explain after this lesson. Use a small, coherent section for the first pass. For a biology class, that might be the inputs, energy change and output of photosynthesis. Keep the original passage open while you inspect the cards. The example below is written for this guide; it is not a report of a model run or a promise about what every upload will produce.

The material we will use

Plants use light energy to convert water and carbon dioxide into glucose. Energy is stored in chemical form, and oxygen is released. This paragraph provides several distinct targets: the energy source, the raw materials, the stored form of energy and a released gas. A weak first card would ask, “Explain photosynthesis.” A student could remember the word glucose, miss the energy change, and still feel that the answer was correct. A more useful question names the part you actually want to assess.

Question
Answer
Why keep it?
What form of energy is stored through photosynthesis?
Chemical energy, stored in glucose.
One identifiable target.
Which two raw materials are used to form glucose?
Water and carbon dioxide.
A small pair with an explicit context.
Which gas is released during photosynthesis?
Oxygen.
Short enough to compare with your recall.

Bring the notes into Deckumi

Sign in before starting your own generation. Choose the file or text creation method, name the flashcard set, and review the source and generation options available in that flow. For a PDF, choose the relevant material rather than assuming an entire book is the right first task. For pasted notes, keep the headings that identify what the paragraph is about. Check the output language before you continue. The website language and the language you want on your cards are related defaults, not a reason to translate your original notes silently. If the source is a scan, confirm that names, symbols and headings survived extraction. A parser can produce readable text that still contains a consequential error.

Review the candidate cards against the passage

Read each question before reading its answer. Ask whether the question makes sense without the source page next to it. Then compare the answer with the passage. Remove claims that the material does not support, and repair references such as “this process” when the card no longer contains the preceding sentence. Do not judge a batch by its size. Three cards you can explain are a better starting exercise than a large batch you cannot check. If the task covers more material than expected, use the available scope controls and inspect the resulting cards rather than assuming every section was covered equally.

Make the first review a quality check

Open the set and attempt one answer before revealing it. If you cannot tell whether your answer counts as correct, edit the question or the reference answer. If you did not understand the passage, return to the notes; a scheduling algorithm cannot supply the missing explanation. After revealing the answer, rate your recall honestly. A wrong answer belongs with Again rather than Hard. Good and Easy describe the recall you actually experienced; they are not a score you are trying to maximize. Deckumi uses those responses in its FSRS review flow.

Keep a small correction loop

After the first session, identify one card that was ambiguous, overloaded or too easy to guess. Rewrite it and revisit the source. Preserve the context that matters, such as a course definition or a version number, instead of shortening every question indiscriminately. Use the PDF example to explore the interaction, then try a passage from your own notes through the real creation flow. When a card is hard for the wrong reason, improve the card before adding more material. This is a repeatable editing habit, not a guarantee of a particular exam result.
