Test yourself with an online bio quiz built from your notes
Upload a lecture PDF, slides or a photo of a textbook page. DeckOwl writes multiple-choice, true/false and short-answer questions, each with an explanation.
Why a custom bio quiz beats a generic one
Biology exams reward recall more than recognition, so the fastest way to find what you do not know is an online bio quiz built from your own notes. Upload a lecture PDF, a set of slides or a photo of a textbook page, and DeckOwl writes multiple-choice, true/false and short-answer questions with an explanation for each answer.
- Quiz yourself on your own lecture slides and chapter notes
- Check understanding with explanations, not just a score
- Mix multiple choice, true/false and short-answer questions
- Export to PDF or DOCX on Plus when you need a printable copy
Multiple choice, true/false and short answer
Mix question types from the same upload so you practice recognition and recall, not just one format.
An explanation for every answer
When you miss a question, the explanation points to the idea you need to review, so you know where to look in your notes.
Works from the material you already have
Read PDFs, DOCX and PPTX files, plain text notes, or photos of pages recognized with text recognition.
How it works
Upload your biology material
Add a PDF, DOCX, PPTX, plain text notes or a photo of a page from your course.
Choose your question types
Pick multiple choice, true/false or short answer, or combine them in one quiz.
Take the quiz and review
Answer in your browser, then read each explanation and retake the questions you missed.
Explanations matter as much as the score. When a question on cell respiration or gene expression is wrong, the explanation shows which step you misremembered, so you can return to that section of your notes instead of rereading the whole chapter.
Quizzes work alongside flashcards and mind maps. Free accounts get 3 generations per month and can study in the browser. Plus adds unlimited generations plus PDF, DOCX, Anki and CSV export.

Frequently asked questions
What biology material works best for an online bio quiz?
Chapter notes, lab handouts and lecture slides with clear definitions and processes tend to produce the most useful questions. Dense, well-labeled material gives the generator more concepts to test.
How should I use a quiz to study biology?
Take the quiz before rereading the chapter, then review every wrong answer and its explanation. Retake the questions you missed a day or two later to strengthen recall.
Can I export the quiz to PDF or Word?
Yes, PDF and DOCX export are included on the Plus plan at $39/year or $7.99/month. Exports are not part of the free plan, which lets you study in the browser.
Can a teacher import the quiz into a learning management system?
The Pro plan at $14.99/month adds QTI 2.1 and Moodle XML export for importing into compatible systems. Students with a school email get 40% off.
