How to run a quiz for a large group

A lecture hall of 200 people needs questions that cover the same material as a small seminar, but writing them by hand takes hours. If you need a free quiz maker for 200 participants, DeckOwl can draft questions and answer keys from your own slides. It generates the content only, so you still need a separate way to collect answers in the room.

Check every generated question against your slides before the session.
Mix question types so recall and reasoning are both tested.
Keep explanations short enough to read aloud during review.
Count your generations before a large session so you do not run out on the free plan.

Example intro cell biology quiz questions

Which organelle is the main site of ATP production in eukaryotic cells?Mitochondria. They carry out oxidative phosphorylation, which produces most of the cell's ATP.

True or false: prokaryotic cells have a membrane-bound nucleus.False. Prokaryotes lack a membrane-bound nucleus, so their DNA sits in the nucleoid region.

What molecule carries amino acids to the ribosome during translation?Transfer RNA (tRNA). Each tRNA matches a codon through its anticodon.

What is the net ATP yield per glucose from glycolysis alone?2 ATP. Glycolysis uses 2 ATP and produces 4, so the net gain is 2.

Which phase of mitosis aligns chromosomes at the cell's equator?Metaphase. Spindle fibers attach to kinetochores and line the chromosomes up along the metaphase plate.

Frequently asked questions

How many questions should a quiz for a large group have?

Ten to twenty questions usually fit a 15 to 20 minute session. Start with the main ideas from your material and add harder questions for review.

What makes a quiz question test understanding rather than memory?

Write one correct answer and plausible distractors that reflect common misconceptions. Avoid all of the above options so the question measures what the participant actually knows.

Does the free plan let me export the quiz?

No. The free plan lets you study in the browser, while PDF and DOCX export start on the Plus plan at $39/year or $7.99/month.

Can DeckOwl run a live quiz with 200 people?

No. DeckOwl generates quiz questions and explanations but does not host live voting, so you will need a separate tool to collect answers in the room.
