What a join code does and what DeckOwl makes instead

If you landed here wanting to enter a Wayground join code, DeckOwl is not the right place for that. Join codes open a live session run by a teacher or host, and DeckOwl does not run those sessions. What it does is take a PDF, slide deck, DOCX, plain-text notes or a photo of a page and produce multiple-choice, true/false or short-answer questions with explanations, so you can practice the material yourself.

  • Upload PDF, DOCX, PPTX, plain text or a photo of a page
  • Multiple-choice, true/false and short-answer questions
  • Explanations for every answer
  • Free plan: 3 generations per month, study in the browser
Example cell biology quiz questions
Which organelle is the main site of ATP production in eukaryotic cells?Mitochondria. They carry out most of the cell's aerobic respiration, which produces ATP.
True or false: plant and animal cells both have a cell wall.False. Only plant cells have a cell wall made mainly of cellulose, while animal cells rely on the plasma membrane alone.
Which structure controls what enters and leaves the cell?The plasma membrane. Its phospholipid bilayer with embedded proteins makes it selectively permeable.
What is the main function of ribosomes?Protein synthesis. They translate messenger RNA into polypeptide chains.
Where does the Krebs cycle take place in eukaryotic cells?The mitochondrial matrix. It runs there after pyruvate is converted to acetyl-CoA.
