What to do if a join code is not working

A live game code only works inside the game that issued it, and DeckOwl does not host Gimkit join sessions or accept codes. What it does is turn the PDFs, slides or notes you already have into multiple-choice, true/false and open questions with explanations, so you can study on your own schedule.

  • Upload PDF, DOCX, PPTX, plain text or a photo of a page
  • Multiple-choice, true/false and short answer questions with explanations
  • Flashcards with spaced repetition and mind maps from the same material
  • Free plan includes 3 generations per month, studied in the browser
Example cell biology quiz questions (not live game codes)
Which organelle produces most of a cell's ATP?Mitochondria. They carry out cellular respiration, which converts glucose and oxygen into ATP.
True or false: plant cell walls are made mainly of cellulose.True. Cellulose fibers give the wall rigidity and help it resist bursting when the cell takes in water.
What does the nucleolus produce?Ribosomal RNA and ribosome subunits, which are assembled there before moving to the cytoplasm.
Which process moves water across a membrane toward higher solute concentration?Osmosis. Water diffuses through the membrane until solute concentrations are more balanced on both sides.
Why do mature human red blood cells lack a nucleus?To make more room for hemoglobin, which lets each cell carry more oxygen.

Questions from your own material

Upload a PDF, DOCX, PPTX, plain text file or a photo of a page and get practice questions based on what you actually study.

Explanations for every answer

Each multiple-choice, true/false and short answer question includes an explanation, so a wrong answer teaches you something.

Study in the browser

The free plan lets you study generated questions, flashcards and mind maps in the browser without a credit card.

How it works

Upload your notes

Add a PDF, slide deck, document or photo of a page from your class.

Choose question types

Pick multiple-choice, true/false or open questions and set how many you want.

Practice and review

Answer the questions, read the explanations and repeat the ones you miss.

Cell biology is a good test case. Once your notes on membranes, organelles and cell division are uploaded, you can review each explanation and repeat the questions you miss until the terms stick.

Frequently asked questions

How many practice questions should I make for a cell biology unit?

Start with 20 to 30 questions covering one chapter at a time. Review the ones you miss, then add new questions for the next topic.

How do I study cell biology questions effectively?

Answer each question before reading the explanation, and write down why the wrong options are wrong. Return to missed questions after a day or two to strengthen recall.

Can I export my questions to Moodle?

Moodle XML export is available on the Pro plan at $14.99 per month. Exports to PDF, DOCX, Anki and CSV are included in the Plus plan.

Is there a free plan?

Yes. The free plan includes 3 generations per month and lets you study in the browser. Exports require a paid plan, and students get 40% off with a school email.
