Get a quiz with answers from your own material

Most teachers who search for a quiz for teachers with answers already have the content they need: a unit slide deck, lecture notes or a textbook chapter. Rather than a ready-made quiz that may not match your sequence, DeckOwl builds one from that material, so each question reflects what you taught and each answer is traceable to a source passage.

Multiple-choice, true/false and short-answer questions from one upload
An answer and explanation for every question
PDF and DOCX export on Plus, with QTI 2.1 and Moodle XML on Pro

Example photosynthesis quiz questions with answers

Where in the chloroplast do the light-dependent reactions take place?In the thylakoid membranes. Light energy is captured there to make ATP and NADPH.

Which gas is released as a byproduct of the light-dependent reactions?Oxygen. It comes from splitting water molecules, not from carbon dioxide.

True or false: the Calvin cycle needs light to run directly.False. It uses ATP and NADPH from the light reactions, so it depends on light only indirectly.

What does RuBisCO do in the Calvin cycle?It fixes carbon dioxide by attaching it to RuBP, which starts the cycle.

Why do C4 plants lose less water on hot days than C3 plants?They fix carbon in mesophyll cells first, which lets their stomata stay mostly closed in heat.

Frequently asked questions

How many questions should a classroom quiz with answers include?

Most short classroom checks work well with 10 to 15 questions that cover one lesson. Longer units can be split into several shorter quizzes so students are not overloaded.

Should answer explanations explain why the wrong options are wrong?

Yes, explaining why a common wrong choice fails helps students correct a specific misconception. A one- or two-sentence explanation per question is usually enough.

Can I export a quiz with answers to PDF or DOCX?

Yes, PDF and DOCX export are included in the Plus plan at $39/year or $7.99/month. The free plan lets you study in the browser but does not include exports.

Does DeckOwl export to Moodle?

Yes, Moodle XML and QTI 2.1 export are included in the Pro plan at $14.99/month. Pro also adds a stronger AI model and bulk upload.
