Why write the answer options yourself when the source already has them

Writing four plausible options and a correct answer for every chapter takes longer than the studying itself, and most of that time goes into guessing what your instructor will ask. A multiple choice question answer generator reads your notes or slides and proposes questions tied to the specific claims in them, so you spend your time answering instead of drafting.

  • Questions are built from the PDFs, slides, or notes you upload, not from generic topic lists.
  • Each item includes the correct answer and an explanation for why it is right.
  • Multiple choice, true/false, and short answer formats are available from the same upload.
  • Free plan includes 3 generations per month with studying in the browser; exports require a paid plan.
Example high school biology multiple choice questions
Which organelle produces most of a cell's ATP?The mitochondrion. It carries out cellular respiration, which converts the energy in glucose into ATP.
Which process moves water across a membrane toward the side with higher solute concentration?Osmosis. Water moves toward the side with lower water potential, which is the side with more dissolved solute.
What does a dominant allele do in a heterozygous pair?It is expressed in the phenotype and masks the recessive allele, so only one copy is needed to show the trait.
What is the main job of helicase during DNA replication?It unwinds the double helix by breaking the hydrogen bonds between base pairs, creating the replication fork.
Which enzyme fixes carbon dioxide in the Calvin cycle?RuBisCO. It attaches CO2 to RuBP, which begins the cycle of carbon fixation.

Questions from your own material

Upload PDFs, DOCX files, PPTX slides, plain text, or photos of pages. The questions come from what you actually studied.

Explanations for every answer

Each question shows why the correct option is right, so a missed question becomes something you learn from rather than just a score.

Spaced repetition for review

Missed questions come back at the right intervals, so the material you struggle with gets more practice over time.

How it works

Upload your material

Add a PDF, slides, notes, or a photo of a textbook page. No credit card is needed to start.

Choose a question type

Pick multiple choice, true/false, or short answer, then generate the set.

Answer, check, and review

Work through the questions in your browser, read the explanations, and revisit the ones you missed.

The quality of a generated question depends on its wrong options. Good distractors are close in length to the correct answer and reflect misconceptions that came up in class, which is what makes a question test understanding rather than recall of the exact wording. Review each question before you rely on it, and check the explanation against the source page.

A practical routine is to answer a set cold, mark what you got wrong, and then reread only the sections behind those misses. Repeating the set a day or two later shows whether the answer stuck or whether you were recognizing the right option from the way it was worded.

Frequently asked questions

How many multiple choice questions should I make per chapter?

Start with 10 to 20 questions per chapter so you can cover the main ideas without overwhelming yourself. Spend extra time on the questions you miss, since they show where your understanding is thin.

How do I write good wrong answers for multiple choice questions?

Make each wrong option plausible and close in length to the correct one. Misconceptions that came up in class make strong distractors because they test real understanding rather than guessing.

Can I export the questions to Moodle or QTI?

Yes, Moodle XML and QTI 2.1 export are on the Pro plan at $14.99 per month. The Plus plan, at $39 per year or $7.99 per month, adds PDF, DOCX, Anki, and CSV export.

Is there a free plan?

Yes, the Free plan includes 3 generations per month and studying in the browser, but no exports. No credit card is needed to start, and students get 40% off with a school email.
