How a quiz maker for uploaded files works

A quiz maker for uploaded files starts with your own material, so the questions reflect the reading, slides or lecture notes you are actually responsible for. DeckOwl accepts PDF, DOCX, PPTX, plain text notes, and photos of pages, which are read with text recognition before questions are written.

Example intro biology quiz questions with answers

Which organelle produces most of a cell's ATP?The mitochondrion. Its inner membrane holds the electron transport chain, which drives most ATP synthesis.

True or false: animal cells have a cell wall.False. Animal cells lack a cell wall, so they rely on the plasma membrane and cytoskeleton for structure.

In osmosis, which way does water move across a selectively permeable membrane?Toward the side with higher solute concentration, where water potential is lower. Water follows the solute gradient across the membrane.

What does DNA polymerase do during DNA replication?It adds complementary nucleotides to a growing strand using the template strand. It also proofreads, which helps keep copying errors rare.

Which molecules from the Krebs cycle carry electrons to the electron transport chain?NADH and FADH2. They deliver electrons to the electron transport chain, where most of the cell's ATP is made.

Works from your own material

Questions come from the file you upload, so the quiz matches what your class actually covered.

Accepts the files you already have

PDF, DOCX, PPTX slides, plain text notes and photos of pages, which are read with text recognition.

Explanations on every question

Each answer includes a short explanation, so a wrong pick teaches you why the right answer is correct.

How it works

Upload your file

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

Choose the question types

Pick multiple choice, true/false or short answer, or mix them in one quiz.

Take the quiz and review

Answer the questions, read the explanations, and study the ones you missed.

Questions come in three formats: multiple choice, true/false and short answer. Each one includes an explanation, so reviewing a missed question shows the reasoning behind the correct answer rather than just marking it wrong.

Frequently asked questions

How many questions should a quiz on one chapter have?

Enough to cover each main idea in the chapter at least once. Start with a short set, then add questions on the topics you keep missing.

Should I quiz myself on the material before or after I reread it?

Try a quiz first, then reread the parts you missed. Testing yourself before you review helps you find gaps you would not notice while rereading.

Which files can I upload to make a quiz?

You can upload PDF, DOCX, PPTX slides, plain text or notes, and images of pages, which are read with text recognition. Each file is turned into questions from its content.

Can I export my quiz?
