Why a custom quiz beats a printable template

A ready-made free biology quiz with answers from a random website rarely matches the chapter your instructor covered, so half the questions can feel irrelevant. Generating one from your own notes keeps the focus on the terms and processes you need.

Questions come from the exact lecture or textbook pages you upload.
Explanations show why the correct answer works, not just what it is.
Multiple-choice, true/false and short-answer formats cover recall and application.
Free plan lets you generate and study in the browser without a credit card.

Example biology quiz questions with answers

What is the net ATP yield of glycolysis per glucose molecule?2 ATP. Glycolysis produces 4 ATP but uses 2 in its investment phase, so the net gain is 2.

True or false: mitochondria contain their own circular DNA.True. Mitochondria carry a small circular genome separate from nuclear DNA, which reflects their bacterial origin.

In which phase of mitosis do sister chromatids separate?Anaphase. Spindle fibers pull the sister chromatids toward opposite poles of the cell.

What does photosystem II release during the light-dependent reactions?Oxygen, produced by splitting water. The electrons from water replace those lost by chlorophyll.

Why does the sodium-potassium pump move 3 Na+ out for every 2 K+ in?The unequal exchange moves more positive charge out than in, which makes the inside of the cell more negative and helps maintain the membrane potential.

Generate the full set

Built from your material

Upload a PDF, DOCX, PPTX, text notes or a photo of a textbook page, and the quiz covers what your class actually taught.

Answers with explanations

Each multiple-choice, true/false or short-answer question comes with the correct answer and a short reason, so you learn from mistakes.

Export when you need a printable copy

Free plan users study in the browser. Plus adds PDF and DOCX export for a printable version of your biology quiz.

How it works

Upload your biology notes

Add a lecture PDF, slides, a DOCX file or a photo of your notes. Text recognition reads images too.

Choose question types

Pick multiple choice, true/false or open questions, then generate the quiz.

Check answers and review

Work through the quiz, read the explanations, and reattempt missed questions until they stick.

Every question includes an explanation, which matters in biology where a wrong answer often hides a misunderstanding about mechanism, such as confusing aerobic and anaerobic steps. Reading the reason next to the answer turns a quiz into a study session.

If you need a printable copy for a study group, Plus lets you export the quiz to PDF or DOCX after generating it from your own material.

Frequently asked questions

How do I check that my biology quiz answers are correct?

Compare each answer against your textbook or lecture slides, and read the explanation to confirm the reasoning. If an explanation doesn't match your course notes, regenerate the quiz from a cleaner copy of the source material.

What makes a good biology quiz question?

Good questions test one idea, such as a process step, a structure and its function, or a cause and effect. Avoid questions that only ask you to recognize a term without explaining why it matters.

Can I export my biology quiz to PDF?

PDF and DOCX export are included with the Plus plan, which costs $39/year or $7.99/month. The free plan lets you study quizzes in the browser without exports.

Is there a free plan?
