Why a custom biology quiz beats a fixed HTML file

A generic biology quiz file was written for someone else's course, so its questions rarely match the chapter your lecture covered last week.

Questions use your course terms and chapter order
Multiple-choice, true/false and open formats in one quiz
Explanations for every answer, right or wrong
Free plan to start, with no credit card required

Example biology quiz questions

Which organelle carries out aerobic respiration in eukaryotic cells?Mitochondria. They produce most of the cell's ATP through the citric acid cycle and oxidative phosphorylation.

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

In photosynthesis, which molecule is split to release oxygen?Water. Photosystem II oxidizes water, and the oxygen is released as a byproduct.

What is the role of the enzyme helicase during DNA replication?It unwinds the double helix by breaking hydrogen bonds between base pairs, which creates the replication fork.

Which phase of mitosis is when sister chromatids separate?Anaphase. Cohesin is cleaved, so sister chromatids are pulled toward opposite poles of the cell.

Questions from your material

Multiple-choice, true/false and open questions are generated from your own PDF, slides, DOCX, text or photographed pages.

Explanations on every answer

Each question includes an explanation so you learn why the right answer is correct, not just which letter to pick.

Study in the browser

Take the quiz online on the free plan, with 3 generations per month and no credit card needed to start.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, plain text file or a photo of your page. Text recognition reads images too.

Choose the question types

Pick multiple-choice, true/false or short-answer questions and set how many you want for the chapter.

Take the quiz and review

Answer the questions, read the explanations for anything you missed, and retake the weak spots.

A quiz built from your own slides or notes uses your instructor's terms, diagrams and emphasis. That makes practice closer to what appears on the exam and shows you gaps in your notes.

Start with a short quiz after each lecture, then build longer mixed sets before the test. Each new set can come from the newest material, so review keeps pace with the course.

Frequently asked questions

How many questions should a biology quiz have for one chapter?

Ten to twenty questions usually cover the main terms and processes in a chapter without making review feel endless. Shorter sets work well for daily practice, and longer mixed sets suit exam prep.

How should I review biology quiz questions I got wrong?

Read the explanation for each missed question and restate the reasoning in your own words. Retake the missed questions a day or two later so the answers stick.

Can I export my biology quiz?

Export is a paid feature. Plus includes PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML for learning management systems. The free plan lets you study in the browser.

Do I need a credit card to try it?

No. You can start on the free plan with 3 generations per month and no credit card. Students get 40% off with a school email.
