Why a quiz from your own notes beats a random YouTube video

A biology quiz built from your own lecture slides tests the exact terms, pathways and diagrams your course uses, which a generic video quiz often misses. Retrieval practice works best when the questions match what you will see on the exam.

  • Questions drawn from your own slides, PDFs or notes
  • Multiple-choice, true/false and short answer formats
  • Explanations that show why each answer is right or wrong
  • Photos of textbook pages read with text recognition
Example biology quiz questions with answers
Which organelle produces most of a eukaryotic cell's ATP?Mitochondria. Oxidative phosphorylation in the inner membrane generates most ATP in aerobic cells.
True or false: DNA replication is semiconservative.True. Each new double helix keeps one original strand and one newly synthesized strand, as Meselson and Stahl showed.
What gas is released as a byproduct of the light reactions in photosynthesis?Oxygen. It comes from splitting water molecules at photosystem II.
What does the sodium-potassium pump do with each ATP it uses?It moves 3 Na+ out and 2 K+ into the cell, helping maintain the resting membrane potential.
Which phase of mitosis separates sister chromatids?Anaphase. Spindle fibers pull the chromatids toward opposite poles of the cell.

Built from your material

Questions come from the chapters, slides or notes you upload, so the quiz matches what your instructor actually covered.

Explanations for every answer

Each question includes a short explanation, so a wrong answer becomes a lesson instead of a dead end.

Works with photos too

Snap a page of your textbook or whiteboard and text recognition reads it into the quiz generator.

How it works

Upload your biology material

Add a PDF, DOCX, PPTX, plain text or photos of pages covering the topic you are studying.

Choose the question types

Pick multiple-choice, true/false or short answer questions, or a mix of all three.

Take the quiz and review

Answer in the browser, read the explanations, and retry the questions you missed.

Video quizzes are useful for a broad overview, but they rarely follow your syllabus or your instructor's emphasis. Generating a quiz from your own material keeps the focus on the topics that will be tested.

On the free plan you can run three generations a month and study in the browser. Plus and Pro add exports for Anki, PDF, DOCX and LMS formats, so you can take the quiz into the tools you already use.

Frequently asked questions

How many questions should a biology quiz have for a unit exam?

Most students find 20 to 30 questions covering one unit a good length for a practice session. Start with a shorter quiz on the hardest sections, then build longer mixed quizzes closer to the exam date.

How do I study biology quiz questions effectively?

Answer each question before checking the explanation, and write down the reasoning for any miss. Retake the questions you got wrong after a day or two, since spacing the review improves retention.

Can I export my biology quiz?

Exports are paid features. Plus includes PDF and DOCX export, while Pro adds QTI 2.1 and Moodle XML for learning management systems.

Do I need a credit card to try it?

No. You can start on the free plan without a credit card, and students get 40% off paid plans with a school email.
