Plus adds PDF, DOCX and Anki export, and Pro adds QTI 2.1 and Moodle XML export

Example biology knowledge quiz questions

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

True or false: DNA replication is semiconservative.True. Each new double helix keeps one original strand and one newly made strand, as Meselson and Stahl showed.

In a cross of two heterozygous plants (Aa × Aa), what fraction of offspring show the recessive phenotype?One quarter (1/4). The cross gives AA, Aa, Aa and aa, and only aa shows the recessive trait.

How do the outcomes of mitosis and meiosis differ?Mitosis produces two genetically identical diploid cells, while meiosis produces four genetically distinct haploid cells. Meiosis is the process that makes gametes.

Which process moves water across a membrane from low solute to high solute concentration?Osmosis. Water moves down its own concentration gradient toward the side with more dissolved solute.

Multiple choice, true/false and open questions

Mix question formats so you test recall, recognition and reasoning instead of memorizing one pattern.

Explanations for every answer

Each question comes with a short explanation, so a wrong answer shows you why the correct biology concept works.

Built from your own material

Upload PDFs, DOCX files, PPTX slides, plain notes or photos of textbook pages, and the quiz follows what your course actually covered.

How it works

Upload your notes

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

Choose your question types

Pick multiple choice, true/false or open questions for the session.

Answer and review

Work through the quiz, read each explanation and retry the questions you missed.

Quizzing yourself on what you were actually taught beats rereading highlighted slides. Wrong answers point you back to the exact idea that needs work, and the explanations give you the reasoning in the same pass, so you are not stuck guessing why an answer was right.

Frequently asked questions

How many questions should a biology quiz cover per study session?

Aim for 10 to 20 questions so you can review every wrong answer while the explanation is still fresh. Spreading short sessions across the week usually works better than one long cram.

Which biology topics should I quiz myself on first?

Start with the topics your exam weights most heavily, then work through processes that build on each other, such as cell respiration before photosynthesis. Quiz terms and processes separately so you can see which one is slipping.

Can I export biology quiz questions to my LMS?

Yes, but exports are paid features. Moodle XML and QTI 2.1 export are on the Pro plan, and PDF, DOCX and Anki export come with Plus.

Is there a free plan?

Yes. The free plan includes 3 generations per month and studying in the browser, and you do not need a credit card to start.
