Why a quiz needs its answers included

A practice quiz only helps if you can tell right from wrong right away, so a good AI quiz generator with answers writes the answer key alongside each question instead of leaving you to guess.

  • Correct answer provided for every multiple-choice, true/false and open question
  • A one-sentence explanation of why the answer is right
  • Questions drawn from your own uploaded material
  • Exports to PDF or DOCX on Plus, and QTI 2.1 or Moodle XML on Pro
Example intro biology quiz questions with answers
Which organelle produces most of a cell's ATP?Mitochondria. They carry out cellular respiration, which generates most of the ATP the cell uses.
True or false: prokaryotic cells have a membrane-bound nucleus.False. Prokaryotes lack a membrane-bound nucleus, so their DNA sits in the cytoplasm in a region called the nucleoid.
What is the main function of ribosomes?Protein synthesis. Ribosomes read mRNA and link amino acids into polypeptide chains.
Which structure controls what enters and leaves the cell?The cell (plasma) membrane. It is a phospholipid bilayer with embedded proteins that regulate transport.
Why do plant cells have a cell wall but animal cells do not?The cellulose cell wall gives plant cells rigid support and shape, which animal cells get from the cytoskeleton instead.

Answers on every question

Each multiple-choice, true/false and open question includes the correct answer, so you can check your work without searching the textbook.

Explanations, not just keys

A short explanation shows why the answer is right, which helps you learn the reasoning behind the fact instead of memorizing a letter.

Built from your material

Questions come from your own PDFs, DOCX files, slides, plain notes or photos of pages, so the quiz matches what your class actually covers.

How it works

Upload your material

Add a PDF, DOCX, PPTX, text file or a photo of a page. Photos are read with text recognition.

Choose the question types

Pick multiple choice, true/false or open questions, or mix them in one quiz.

Check answers and explanations

Work through the quiz, then read the answer and explanation for each question you missed.

When you study a unit like cell biology, the most useful answers explain the mechanism behind the fact. Seeing why mitochondria produce ATP, or why plant cells have a cell wall, makes the next related question easier to reason through.

Frequently asked questions

How many practice questions should I answer in one session?

Most students do well with 10 to 20 questions at a time, which is enough to find weak spots without fatigue. Review every answer you missed before starting a new set.

Should I read the explanation before or after I answer?

Answer first without looking, then read the explanation, even if you got it right. Explaining why the other options are wrong builds stronger recall than seeing the correct answer alone.

Can I export quizzes with answers to Word or PDF?

Yes, PDF and DOCX export is included on the Plus plan at $99.90/year or $9.99/month. QTI 2.1 and Moodle XML export are available on the Pro plan at $14.99/month.

Is there a free way to try it first?

The free plan includes 3 generations per month and studying in the browser, and no credit card is needed to start. Students with a school email get 40% off Plus.
