How correct answers work in a Google Forms quiz

Setting up a graded form means every question needs a marked answer, and quiz correct answers are the step most people leave until last. The answer key is only as good as the question behind it, so the key has to match the material your class actually covered.

Turn on Make this a quiz in Settings before adding answer keys.
Give each question a point value so the total score matches your plan.
Decide when respondents see their score under Release marks.
Test the finished form once, then compare each score with your notes.

Correct answers with explanations

Each multiple-choice, true/false or open question comes with its correct answer and a short explanation of why it is right.

Generate the quiz

Choose multiple-choice, true/false or open questions. Each one arrives with its correct answer and an explanation.

Check and copy into your form

DeckOwl reads your PDFs, slides or notes and writes multiple-choice, true/false and open questions. Each question includes its correct answer and a one-sentence explanation, so you can check the key against the source before you enter it in Google Forms.

Google Forms does not receive a finished quiz from DeckOwl, so the questions are copied across by hand. That short review step is also where you catch a wrong option or a vague explanation.

Frequently asked questions

How do I set correct answers in a Google Forms quiz?

Turn on Make this a quiz under Settings, then open each question and choose the right option under Answer key. Add a point value to each question so the total score is clear.

Why does a quiz answer need an explanation as well as a key?
