Turn a YouTube video into practice tests, checked against your material
Upload a YouTube video and QuerySpark writes practice tests from what is actually in it, so you can rehearse the real exam on exactly what your course covers. Any public YouTube video with captions.
Example
Practice test from Lecture
A sample of what you get from a YouTube video on physics. Yours is written from your own file.
Question 1 · Multiple choice
A 2 kg cart accelerates at 3 m/s². What net force acts on it?
- 1.5 N
- 5 N
- 6 N
- 9 N
Newton's second law: F = ma = 2 × 3 = 6 N.
Question 2 · Multiple choice
Why does a passenger lurch forward when a bus brakes suddenly?
- The brakes push the passenger forward
- The passenger's body tends to keep moving at the original speed
- Gravity increases during braking
- Friction from the seat pushes forward
Newton's first law: without a net force, a body keeps its velocity, so the bus slows while the passenger does not.
Question 3 · Short answer
If action and reaction forces are equal, why does a horse pulling a cart move forward?
Model answer: The pair acts on different bodies; the horse moves because the ground's forward push on its hooves exceeds the cart's backward pull.
How we read YouTube videos
Paste the link and we pull the video's transcript, then build questions only from what was actually said, so the set matches the lecture you watched rather than the topic in general.
Get the best results
- Lecture recordings and Crash Course style explainers work best.
- For a playlist, generate one set per video and study them together.
What your practice tests include
- A timed, exam-style test mixing question types
- A score at the end, with every question you missed explained
- Questions pitched at the level you choose, from high school to professional
- The source passage behind every answer, so you can check it yourself
How you study them
Take it under exam conditions, then review your misses. Questions you got wrong go into your review queue so they come back before the real exam.
Best for: mock exams, measuring readiness, teachers building assessments.
Things that trip people up with YouTube videos
- Videos without captions cannot be read from the link. Download the audio and upload it as a recording instead.
- Fast-talking explainers pack a lot in; pick a set size that matches the video length.
Questions about youtube to practice test
Do I need to download the video?+
No. Paste the YouTube link. We only need the captions, which most lectures and explainers have.
What if the video has no captions?+
Upload the audio as a lecture recording instead; we transcribe it before writing questions.
Can teachers assign the test to a class?+
Yes. Create a class, share the join code, and assign the set. You see each student's progress on every assignment.
Is the youtube video to practice test converter free?+
Yes. You can try it free with a 3-day Pro trial and no credit card, then keep using the free plan every month.
