How to get quiz questions and answers from a video lesson

Most video lessons can't be turned into a quiz directly, but the words behind them can. A transcript, the captions or the slide deck usually holds the same key terms and claims, and DeckOwl drafts video quiz questions and answers from that text so you can test yourself on the lecture afterward.

  • Paste a transcript or captions when a lecture has no slides
  • Use short answer questions to test recall, not just recognition
  • Read the explanation before moving on from every wrong answer
  • Regenerate from a different section when a topic needs more practice
Example biology quiz questions with answers
Which organelle produces most of a cell's ATP?Mitochondria. They carry out cellular respiration, which generates most of the ATP the cell uses.
True or false: In osmosis, water moves toward the side with higher solute concentration.True. Water follows its concentration gradient toward the side with less free water, which is the side with more solute.
What is the role of helicase in DNA replication?It unwinds the double helix by breaking hydrogen bonds between base pairs, which opens the replication fork.
Which phase of mitosis lines chromosomes up along the cell's equator?Metaphase. Spindle fibers attach to the chromosomes and align them at the metaphase plate.
Why do enzymes lose function at very high temperatures?Heat disrupts the weak bonds that hold the enzyme's shape, so the active site no longer fits its substrate.

Frequently asked questions

Can DeckOwl make quiz questions from a video file?

DeckOwl doesn't accept video files directly. Paste the transcript or captions, or upload slides, a PDF or a DOCX file that covers the same lesson.

How do I study quiz answers so I remember them?

Cover the answer, say it out loud or write it from memory, then check the explanation. Repeat the questions you missed after a day or two.

Do I need to pay to export quiz questions?

The free plan studies in the browser without exports. Plus at $39/year or $7.99/month adds PDF, DOCX, Anki and CSV export, and Pro at $14.99/month adds QTI 2.1 and Moodle XML.

What should a good biology quiz question test?

Focus on a single process or term per question, such as what enzymes do or how mitosis stages differ. Short answer questions show whether you can explain an idea, which multiple choice alone may not reveal.
