Why a quiz beats rereading your notes

Lecture notes are full of testable facts, but rereading them feels productive without showing what you actually remember. Uploading your material and turning notes into quizzes makes you pull each answer from memory, which is the part of studying that sticks.

Questions are generated from the text of your own notes, slides or PDFs.
Each question includes an explanation, so wrong answers become study points.
Photos of pages are read with text recognition before questions are written.
The free plan includes three generations per month and studying in the browser.

Example digestive system quiz questions

Which organ produces bile?The liver. It makes bile, which emulsifies fats so digestive enzymes can act on them, and the gallbladder stores it.

True or false: most nutrient absorption happens in the large intestine.False. The small intestine has villi and microvilli that give it a large surface area, while the large intestine mainly absorbs water and electrolytes.

Which stomach enzyme begins protein digestion?Pepsin, which is activated from pepsinogen by hydrochloric acid and cuts proteins into smaller peptides.

Which structure folds over the airway during swallowing?The epiglottis. It keeps food out of the trachea so the bolus passes into the esophagus.

Where does salivary amylase begin digesting starch?In the mouth. It starts breaking starch into smaller sugars, though the process is short because the stomach acid stops it.

Frequently asked questions

How many questions should a quiz on the digestive system have?

Ten to fifteen questions covers the main organs and their functions for a typical lecture. Shorter quizzes work well for a single organ, such as the stomach or small intestine.

What should I focus on when studying digestion?

Focus on the order the organs come in, what each one adds to food, and where most absorption happens. Enzymes and where they act are the details most often tested.

Can I turn photos of my notes into a quiz?

Yes. Photos of pages are read with text recognition, and that text is used to write the questions. Check the questions against your source, as with any AI output.

Is exporting my quiz to QTI or Moodle XML free?

No. PDF, DOCX, Anki and CSV export are on Plus, and QTI 2.1 and Moodle XML export are on Pro. The free plan includes three generations per month and studying in the browser.
