Why write your own questions
Testing yourself helps only if there is something good to be tested on. You can buy or find ready-made questions for some subjects, but many topics, such as a particular course, a work skill or a hobby, come with none. Writing your own fills that gap, and the act of writing is itself a form of study. To turn material into a question, you have to decide what matters, which is already a step toward understanding it.
Questions you write also match what you are actually learning. Instead of drilling a generic set, you test exactly the points covered in your own lessons.
What a good question looks like
A useful question is:
- Specific. “What happened in the war?” is vague. “What were two main causes of the conflict?” has a clear scope.
- Answerable from memory. It should have an answer you can state in a sentence or short paragraph, not an essay topic with no edges.
- Checkable. You should be able to look at your notes afterward and tell whether you were right. If the answer is not written down somewhere, you cannot give yourself feedback.
- Focused on one idea. If one question has three parts, you may get two right and not know where you stand. Split it.
- Free of clues. Avoid wording that gives away the answer. If the question includes the term you are trying to recall, it tests very little.
Turning material into questions
From headings and key terms
Take each heading in your notes and rephrase it as a question. “Photosynthesis” becomes “What are the inputs and outputs of photosynthesis, and where does it take place?” Terms become “What does X mean?” or, better, “How would you describe X in your own words?”
From statements
Look for sentences containing a claim, then hide the important part. “The treaty ended the conflict” becomes “What did the treaty end?” or “How did the conflict end?” This is how many flashcards are made, and it works well for facts, dates, definitions and steps.
From examples and problems
For subjects with problems, such as math, save a few worked examples and write the problem statement on one side, leaving the solution on the other. Then try to solve it without looking. Better still, change the numbers or setting to create a similar problem you have not seen.
From lectures and videos
While learning from a lecture or video, jot down questions as they occur, then answer them later from memory. A good rule is to write a question for each main point as you go instead of rewriting everything the speaker said.
Varying the difficulty
A set of questions made only of definitions can leave you able to recite facts but unable to use them. A balanced set includes several levels.
- Recall. What is it? What are the steps? Who, what, when?
- Explanation. Why does it work this way? What causes this? How does A lead to B?
- Comparison. How does this differ from that? When would you use one over the other?
- Application. Given this new situation, what would you do or predict? How would you solve this problem?
- Evaluation. What are the strengths and weaknesses of this argument or method? What is missing?
Start with recall questions when the material is new, then add the others as your understanding grows. If you only ever write the easy kind, your practice will feel smooth and tell you little. A mix gives more honest information about what you actually know, which relates to the illusion of knowing.
An example
Suppose you have a paragraph of notes on how a savings account works (hypothetical material for illustration).
- Recall: “What is interest?”
- Explanation: “Why does money in a savings account tend to grow over time?”
- Comparison: “How does simple interest differ from compound interest?”
- Application: “If you leave money untouched for several years, what happens to the interest you earn each year, compared with the first year?”
Each question has a different purpose, and each can be checked against the notes.
Common mistakes
- Writing questions that are too easy. If you can answer instantly every time, the question may not be pushing your memory.
- Copying sentences word for word. If the answer must match your notes exactly, you test wording instead of understanding. Allow your own phrasing, as long as the meaning is right.
- Making questions too big. “Explain the entire history of the Roman Empire” is a topic, not a question. Break it up.
- Writing and never using them. The writing is only half the job. Schedule time to answer them, ideally with spaced repetition so that you return to the questions over days and weeks.
- Never revising questions. If a question confuses you each time, rewrite it. A confusing question is not a measure of your knowledge.
Using the questions well
Attempt every answer before checking it. Say it aloud or write a few words, then compare. Mark which ones you missed and give those extra attention. Keep a record of repeated misses, since patterns often point to a deeper misunderstanding, and this feeds directly into using error feedback.
For retention, return to the same questions after a gap instead of repeating them in one go. Questions you consistently get right can be spaced further apart or retired. You do not need hundreds of them: a modest, well-made set you actually use is better than a large one that sits unopened.
When to ask for help
If you cannot write a good question because you cannot tell what is important in the material, that is a signal worth noticing. It may mean you need to reread more slowly, ask a teacher or peer, or try a different explanation. Asking questions is a skill in its own right, and the questions you cannot yet form are often the best guide to where to look next.
