Why a free quiz maker helps before an exam

Most students end up with a stack of lecture slides and no practice questions a week before the test. A free quiz maker can turn those slides into questions you can answer on your own schedule.

Generate quizzes from PDFs, slides, notes and photos of pages
Get multiple-choice, true/false and short answer questions with explanations
Study in the browser on the free plan with 3 generations per month
Export to PDF, DOCX, Anki or CSV on Plus, and QTI or Moodle XML on Pro

Example cell biology quiz questions

Which organelle produces most of a cell's ATP through aerobic respiration?Mitochondria. The citric acid cycle and electron transport chain take place there and generate most of the cell's ATP.

True or false: the nucleolus is enclosed by a membrane.False. The nucleolus has no membrane; it assembles ribosomal subunits inside the nucleus.

What is osmosis?The movement of water across a selectively permeable membrane, from lower solute concentration to higher solute concentration.

Which phase of mitosis separates sister chromatids?Anaphase. Spindle fibers pull the sister chromatids toward opposite poles of the cell.

What does the Golgi apparatus do to proteins made in the rough ER?It modifies, sorts and packages them into vesicles for transport. Proteins pass through it after leaving the ER.

Generate the full set

Three question types

Get multiple-choice, true/false and short answer questions from the same material, so you can test recognition and recall.

Explanations for every answer

Each question comes with a short explanation of why the correct answer is right, so missed questions become lessons.

Works from your own material

Build quizzes from your lecture slides, textbook chapters or handwritten notes instead of generic question banks.

How it works

Upload your material

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

Choose a question type

Pick multiple-choice, true/false or short answer, then generate the quiz.

Take the quiz and review

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

Quizzes work best when you answer from memory and then check your reasoning. Multiple-choice questions help you compare close options, true/false questions catch misconceptions, and short answer questions force you to explain a concept in your own words.

The free plan includes 3 generations per month and browser study. Plus and Pro add unlimited generations and export options for when you need questions outside the app.

Frequently asked questions

How do I study cell biology with practice quizzes?

Answer each question from memory before checking the answer, then write one sentence explaining why the correct choice is right. Retake the questions you missed the next day to strengthen recall.

What makes a good quiz question for cell biology?

A strong question tests one idea, such as the function of an organelle or the stage of mitosis, and has distractors that reflect common mix-ups. Short answer questions are especially useful for checking whether you can explain a process.

Is the free quiz maker really free?

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

Can I export my quizzes?

Exports are part of the paid plans. Plus includes PDF, DOCX, Anki and CSV export, and Pro adds QTI 2.1 and Moodle XML export.
