Quiz questions built from your own material

Many teachers and students searching for Quizizz and Kahoot-style quizzes want a fast way to review before a test. DeckOwl does not host live games. It writes the question set from your slides, notes or PDF, so the quiz covers what was actually taught.

  • Questions drawn only from the material you upload
  • Multiple-choice, true/false and short-answer formats
  • Explanations written for every answer
  • Paid exports to PDF, DOCX, QTI 2.1 and Moodle XML
Example chemical bonding quiz questions
Which bond forms when electrons are shared between two nonmetal atoms?A covalent bond. Shared electron pairs hold nonmetal atoms together, unlike the electron transfer seen in ionic bonds.
True or false: NaCl is held together by ionic bonding.True. Sodium transfers an electron to chlorine, and the resulting oppositely charged ions attract each other.
Why is a water molecule polar?Oxygen pulls shared electrons more strongly than hydrogen, so the molecule has a partial negative end and partial positive ends.
What type of bonding holds a metal together as a lattice of positive ions?Metallic bonding. Delocalized electrons move freely through the lattice, which lets metals conduct electricity.
Why does carbon dioxide have no net dipole even though its C=O bonds are polar?Its linear shape makes the two bond dipoles point in opposite directions, so they cancel out.

Frequently asked questions

How many quiz questions should I write for a chemical bonding review?

Ten to fifteen questions usually cover ionic, covalent and metallic bonding plus molecular shape without overloading a single session. Focus each question on one idea, such as electron transfer versus sharing.

What makes a good chemical bonding quiz question?

A good question tests reasoning, not just memory, such as predicting bond type from element positions on the periodic table. Pair each answer with a short explanation so students can see the logic behind it.

Can I run the quiz live with my class?

DeckOwl creates the questions and explanations but does not run a live game session. Paid plans let you export the set to PDF, DOCX, QTI 2.1 or Moodle XML for use in other tools.

Is there a free plan?

Yes. The free plan includes 3 generations per month and studying in the browser, but exports require the Plus or Pro plan.
