Why build a quiz from your own notes

Many students who look for a random multiple choice question generator want questions drawn from their own lecture notes rather than a generic quiz bank. A quiz based on what your instructor actually covered tests the material you will see on the exam.

  • Questions come from the files you upload, not from a shared question bank.
  • Each question has an explanation that shows why the right answer is correct.
  • Photos of printed pages are read with text recognition, so handwritten-free scans still work.
  • The free plan includes browser study, and students get 40% off with a school email.
Example intro biology multiple choice questions
Which organelle is the main site of aerobic respiration in eukaryotic cells?The mitochondrion. It carries out the citric acid cycle and oxidative phosphorylation, which produce most of the cell's ATP.
Which molecule carries amino acids to the ribosome during translation?Transfer RNA (tRNA). Its anticodon pairs with a matching codon on the mRNA.
What is the net yield of glycolysis per glucose molecule?2 ATP and 2 NADH. Glycolysis spends 2 ATP in its early steps and produces 4 ATP, so the net gain is 2.
Which process moves water across a semipermeable membrane toward the side with higher solute concentration?Osmosis. Water moves toward the side with lower water potential, which is the side with more solute.
In a cross of two heterozygotes (Aa × Aa), what fraction of offspring show the recessive phenotype?One quarter (aa). The Punnett square gives 1 AA : 2 Aa : 1 aa, so only one in four is aa.

Frequently asked questions

How many multiple choice questions should I make from one chapter?

Start with 10 to 15 questions per chapter and focus on key terms, processes and cause-and-effect relationships. Add more if the chapter has many definitions to memorize.

What makes a good multiple choice distractor?

Wrong options should sound plausible and belong to the same category as the correct answer. Avoid giveaways such as "all of the above" or a correct answer that is much longer than the others.

Can I export the questions?

Exports are paid features. Plus includes PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML export.

Is there a free plan?

Yes. The free plan includes 3 generations per month and studying in the browser, and no credit card is needed to start.
