Example quiz-writing checks for teachers

Which question type best checks whether a student can explain a process in their own words?Short answer. Multiple choice only asks students to recognize an option, while a short-answer item requires them to produce the explanation themselves.

Why should distractors in a multiple-choice item be plausible?Plausible distractors reveal real misconceptions, while obviously wrong options let students guess without knowing the material.

Why is a true/false item a weak test for complex claims?Students can guess the correct answer half the time, so it shows little about understanding. Use true/false for simple facts or ask students to justify their answer.

What is the main problem with the answer choice all of the above?Students can pick it after spotting two correct options, without knowing the full content. Use it sparingly or replace it with specific options.

Why should every quiz question include an explanation?An explanation turns a wrong answer into feedback, so students learn the reasoning behind the correct option.

Generate the full set

Three question types

Multiple choice, true/false and short answer, so you can match the format to what you want students to show.

Explanations on every question

Each item includes an explanation, so students learn why an answer is right or wrong instead of only seeing a score.

Start from your own material

Upload PDFs, DOCX files, PPTX slides, plain notes or photos of pages, and build quizzes from the content you teach.

How it works

Upload your material

Add a PDF, slide deck, Word document, text notes or a photo of a page.

Choose question types

Pick multiple choice, true/false or short answer, then generate a draft quiz from your lesson.

Review and study

Check the questions and explanations, then study in the browser. Exports are available on paid plans.

Question quality still depends on the teacher. Plausible wrong answers reveal real misconceptions, and short-answer items test explanation better than simple recognition. Use each draft as a starting point and adjust the wording to match your learning goals.

If your school runs an LMS, export format matters. Paid plans include PDF and DOCX exports, and the Pro plan adds QTI 2.1 and Moodle XML so quizzes can move into your course system.

Frequently asked questions

How long should a classroom quiz be?

There is no fixed rule. Match the number of questions to the time you have and the skill you want to check, and keep short-answer items fewer than multiple-choice items so grading stays manageable.

What makes a multiple-choice question fair?

Each wrong option should be plausible and based on a real misconception, and only one option should be clearly correct. Avoid answer choices like all of the above, since students can guess them without knowing the content.

Can I export my quizzes to Moodle?

Yes, Moodle XML export is included on the Pro plan, along with QTI 2.1 export. PDF and DOCX exports are on the Plus plan.

Do I need a credit card to start?

No. You can start on the free plan without a credit card. The free plan includes 3 generations per month and studying in the browser, but no exports.
