How to make a Google Forms quiz that grades itself

The answer key sits on each question, not in a separate sheet. For choice questions you tick the correct option or options; for short answer you list the answers you will accept. Google's help page lists six question types that support an answer key: short answer, multiple choice, checkboxes, dropdown, multiple choice grid and checkbox grid. Paragraph is not on the list, so those answers need grading by hand.

Checkbox questions deserve a check before you publish. Mark every correct option, then take the quiz in preview with a partly correct selection so you see exactly how Google scores it for your settings. For short answer, add every spelling and format you are willing to accept, because the key is only as generous as the answers you type in.

Response validation is a different tool. It checks the format of an answer (a number between 1 and 10, at least 50 characters, text matching a regular expression) and stops submission if the format is wrong. It does not award points, and it should not be used to check correctness, because it tells the student their answer is invalid before they submit.

If you chose "Immediately after each submission", scores appear to the respondent straight away, along with whatever you allowed in the respondent settings. If you chose "Later, after manual review", nothing is shown until you release it.

To release, open the Responses tab. You can grade in three views: Summary, Question (one question across everyone) and Individual (one person at a time). Grading by individual needs email addresses, so turn on email collection before you share the quiz. When a response is graded, click "Release score" at the top right of a response that has a recorded email address. That releases the result to that person.

The most common reason "release score" appears missing is that the quiz is set to release immediately, or the form was not collecting email addresses when the response came in.

Locked mode stops students browsing other sites or opening other apps while they take the quiz. Google's requirements are specific: a Google Workspace for Education account, a Chromebook managed by the school for each student, and ChromeOS 75 or later. It does not work on personal laptops, phones or unmanaged devices.

Turn it on in the quiz settings under Chromebook settings. Locked mode collects email addresses and limits the quiz to your domain. If a student exits the quiz or opens another tab, the teacher is emailed, and a teacher is also emailed if the student reopens it within 30 days.

In Classroom you can create a quiz assignment that attaches a Google Forms quiz, and import grades back into Classroom automatically. Google lists three conditions for grade importing: the quiz must be the only attachment on the assignment, students are limited to one response and must be in the same domain as the teacher, and the form must collect student email addresses. If grades do not import, check those three first.

Knowing the limits up front saves a rebuild. These are the ones people search for most.

None of Google's quiz help pages documents a time limit setting, which is why "how to make a quiz in Google Forms with time limit" is such a common search. Timers come from third-party Marketplace add-ons, which need their own permissions and review. Without one, the practical options are a scheduled close time for the whole form or a supervised session.

A Google Forms quiz shows a score, but it cannot send someone with 9 out of 10 to one result page and someone with 4 to another. Its branching works by section and only from multiple-choice or dropdown answers, not from the running total. Personality quizzes and "which product fits you" quizzes need a workaround or another tool. Our guide to building a quiz with different results based on score covers the options.

"Limit to 1 response" requires every respondent to sign in to a Google account. That suits a class on school accounts, but it blocks public quizzes where people don't want to sign in or don't have a Google account.

Design options are narrower than in dedicated quiz tools, and Google branding stays on every form. Google's help pages document positive point values per question; they do not describe a setting that subtracts marks for wrong answers, so check in preview before relying on it.

Zunoform is an alternative when you need what Google Forms quizzes lack: different result screens by score range or by answer mapping, grade bands, per-question explanations, and a quiz people can take without signing in to Google. Scoring is on every plan, including Free with 500 responses a month, and the score is recalculated on the server at submission. For quizzes that only show results at the end, the answer key is not sent to the respondent's browser. Zunoform can import an existing Google Form to start from.

Where it doesn't fit: there are no timers and no proctoring, and a respondent can retake a quiz to learn answers unless you turn on one response per person, so treat it as a tool for practice quizzes, knowledge checks and lead-generation quizzes, not high-stakes exams. For a class already on Google Workspace for Education, Google Forms with Classroom grade import and locked mode is free and better integrated.
