Why teachers and students use an MCQ maker website

Most people who try an MCQ maker website want questions built from material they already have, not generic banks they have to adapt. Typing every option and explanation by hand takes hours that are better spent studying.

Questions are based on the text you upload, not a fixed bank.
Each item includes an explanation for the correct answer.
Mix multiple-choice, true/false and short-answer formats in one set.
Export options depend on your plan, so check what is included before you need it.

Example probability basics multiple-choice questions

If a fair coin is flipped twice, what is the probability of getting two heads?1/4. There are four equally likely outcomes (HH, HT, TH, TT), and only one of them is HH.

True or false: two mutually exclusive events are always independent.False. If one event occurs, the other cannot, so knowing one changes the probability of the other.

A bag has 3 red and 2 blue marbles. What is the probability of drawing a red marble?3/5. There are 5 equally likely marbles to draw, and 3 of them are red.

If P(A) = 0.4, P(B) = 0.5, and A and B are independent, what is P(A and B)?0.2. For independent events, P(A and B) equals P(A) times P(B), so 0.4 x 0.5 = 0.2.

If P(A) = 0.7, what is the probability of the complement of A?0.3. The complement of A has probability 1 - P(A), so 1 - 0.7 = 0.3.

Review and study

Check each question and explanation, then practice in the browser or export.

A good generated quiz should match the lecture order and vocabulary of your course. Review each question before using it, since the explanation shows why the correct choice is right and the distractors are wrong.

Start with one chapter or one set of slides. Once the questions read the way you want, generate the rest of the unit.

Frequently asked questions

How do I write a good multiple-choice question about probability?

Ask about one idea, such as independence or complementary events, and make each distractor reflect a common mistake. Keep the options similar in length so the correct answer does not stand out.

Why are mutually exclusive events not the same as independent events?

Mutually exclusive events cannot both happen, so knowing one occurred tells you the other did not. Independent events are unaffected by each other, so the two ideas usually produce different probability calculations.

Can I export my quiz to Moodle or QTI?

QTI 2.1 and Moodle XML export are included in the Pro plan at $14.99/month. PDF and DOCX export are included in Plus at $39/year or $7.99/month.

Is there a free plan?

The free plan includes 3 generations per month and studying in the browser, but no exports. No credit card is needed to start.
