Why generate a star quiz from your own notes

Studying stellar classification, the Hertzsprung-Russell diagram or the life cycle of a star usually means rereading slides, and an AI star quiz maker can turn those same pages into practice questions in a few minutes.

Quiz questions drawn from your own slides, PDFs and notes
Multiple-choice, true/false and short answer formats with explanations
Free plan with 3 generations per month and no credit card needed to start
Paid plans add PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML export

Example star quiz questions for astronomy

Which type of star is the Sun?A G-type main-sequence star, sometimes called a yellow dwarf. It fuses hydrogen into helium in its core, which is why it sits on the main sequence.

True or false: stars are powered mainly by chemical combustion, like burning wood.False. Stars are powered by nuclear fusion in their cores, which releases far more energy than any chemical reaction.

What mainly determines whether a star ends as a white dwarf or a neutron star?Its initial mass. Lower-mass stars leave white dwarfs, while much more massive stars can collapse into neutron stars after a supernova.

Why do stars appear to twinkle when viewed from Earth?Turbulence in Earth's atmosphere bends starlight and shifts its apparent position and brightness from moment to moment.

What does a Hertzsprung-Russell diagram plot?Stellar luminosity or absolute magnitude against surface temperature or spectral class. Most stars fall along the main sequence band.

Three question types

Multiple-choice, true/false and short answer questions are generated from your material, each with an explanation of the correct answer.

Reads your own sources

Upload PDFs, PPTX slides, DOCX files, plain text or photos of pages. Text in images is read with text recognition.

How it works

Upload your material

Add the PDF, slides or notes from your astronomy class, or photograph a page from your textbook.

Choose a question type

Pick multiple-choice, true/false or short answer questions and generate a quiz from your own content.

Answer and review

Work through the questions, then read the explanation for each one to see why an answer is right or wrong.

Questions written from your own lecture material match the terms and examples your instructor uses, which makes self-testing more useful before an exam than generic quizzes found online. Review the explanations after each attempt so mistakes turn into targeted study.

Frequently asked questions

What is the difference between a star's luminosity and its apparent brightness?

Luminosity is the total energy a star emits per second, while apparent brightness is how bright it looks from Earth. A faint nearby star can look brighter than a much more luminous star that is farther away.

How can I remember the life stages of a star?

Tie each stage to the mass that determines it, such as main sequence, red giant, then white dwarf, neutron star or black hole depending on mass. Practicing short answer questions helps you recall the order without rereading.

Can I export my star quiz to a learning management system?

Export is a paid feature. PDF and DOCX export are included in Plus, and QTI 2.1 and Moodle XML export are included in Pro.

Do I need a credit card to try it?

No. The free plan includes 3 generations per month and studying in the browser, and you can start without a credit card.
