Why a custom quiz beats a downloaded template

Most free question banks are written for someone else's course, so the wording and coverage rarely match your lecture. DeckOwl does not require a download. Upload your own material and get a multiple choice questions maker that writes questions from your slides, chapters or notes.

  • No install: the quiz maker works in your browser on any computer.
  • Questions are based on the files and notes you upload.
  • Each answer includes an explanation you can review.
  • Free plan includes 3 generations per month, with exports on paid plans.
Example intro biology multiple choice questions
Which organelle is the main site of aerobic respiration in eukaryotic cells?The mitochondrion. It runs the Krebs cycle and electron transport chain, which produce most of the cell's ATP.
Which type of RNA carries amino acids to the ribosome during translation?Transfer RNA (tRNA). Its anticodon pairs with the matching mRNA codon, so the correct amino acid is added.
During which phase of mitosis do sister chromatids separate?Anaphase. Spindle fibers pull the sister chromatids toward opposite poles of the cell.
In DNA, which base pairs with adenine?Thymine (T). A and T form two hydrogen bonds, while G and C form three.
True or false: passive diffusion requires ATP.False. Passive diffusion moves molecules down their concentration gradient without energy, while active transport needs ATP.

Multiple choice and true/false

Choose the question types you need, and each one includes the correct answer with a short explanation of why it is right.

Works from your own material

Upload PDFs, DOCX, PPTX, plain text or photos of pages, and the questions are written from that content.

Study in the browser

Take quizzes right away on the Free plan. Exports to PDF, DOCX, Anki and CSV are available on Plus.

How it works

Upload your material

Add a PDF, slide deck, document or photo of your class notes.

Pick the question types

Select multiple choice, true/false or short answer and set how many you want.

Quiz yourself or export

Practice in the browser, or export to PDF or DOCX on Plus to print or share.

Because every question comes with an explanation, you learn why the wrong options are wrong, which is where most of the study value sits. You can also regenerate a set when you move on to the next unit.

Plus adds unlimited generations and PDF, DOCX, Anki and CSV exports at $39/year or $7.99/month. Pro adds QTI 2.1 and Moodle XML export for teachers who run quizzes in a learning management system.

Frequently asked questions

How many practice questions should I write for an intro biology unit?

There is no fixed number, but a set of 10 to 20 questions per lesson covers most key terms. Focus on the concepts your instructor emphasized rather than trying to cover every detail in the chapter.

How do I study multiple choice questions effectively?

Answer each question before looking at the options, then read the explanation for every wrong choice, not only the one you missed. Repeat the questions you got wrong after a day or two.

Is there a free multiple choice questions maker I can download?

DeckOwl runs in the browser, so there is nothing to download. The Free plan includes 3 generations per month and studying in the browser, but exports are on paid plans.

Can I export my quiz for my class?

Yes. PDF, DOCX, Anki and CSV export are on the Plus plan, and QTI 2.1 and Moodle XML export are on Pro.
