Why practice from your own code notes works better

Programming quizzes test whether you can predict what code does, so the best practice comes from your own slides and notes. DeckOwl reads your files and writes questions with explanations that walk through the answers from code you are expected to know.

  • Questions are generated only from the files you upload.
  • Each answer includes an explanation you can check against your notes.
  • Missed questions return through spaced repetition.
  • Free plan includes 3 generations per month and browser study.
Example Python basics quiz questions
What does print(len("quiz")) output?4. len counts every character in the string, so the four letters count as four.
What is the value of 7 // 2 in Python?3. The // operator is floor division, which drops the remainder.
True or false: in Python, list indexes start at 1.False. Indexes start at 0, so my_list[0] refers to the first item.
After x = [1, 2, 3] and x.append(4), what is x?[1, 2, 3, 4]. append adds the new item to the end of the same list.
What does this print: for i in range(3): print(i)0, 1 and 2 on separate lines. range(3) starts at 0 and stops before 3.

Built from your material

Upload PDFs, slides, DOCX files, plain notes or photos of pages, and get questions based only on what you gave it.

Explanations for every answer

Multiple-choice, true/false and short-answer questions come with a short explanation of why the correct answer holds.

Spaced repetition

Missed questions come back at increasing intervals, so code concepts stick past the night before the quiz.

How it works

Upload your notes

Add a lecture PDF, slide deck, DOCX file or pasted text from your programming course.

Choose a question type

Pick multiple-choice, true/false or open questions, then generate a set from your material.

Practice and review

Answer the questions, read the explanations and study the ones you missed until you can predict the output yourself.

Good code questions focus on output, control flow and common mistakes, such as off-by-one errors in loops or confusing a list with a copy of it. Working through them in your own words builds the habit of tracing code line by line, which is what exams usually check.

Because every question comes from material you uploaded, you can see exactly which lecture or chapter it covers and go back to that section when an explanation does not make sense.

Frequently asked questions

What kinds of code questions can DeckOwl make?

DeckOwl can write multiple-choice, true/false and short-answer questions based on the code examples, output rules and concepts in your uploaded material. Each question includes an explanation of the correct answer.

How should I study programming quiz questions?

Predict the output before you read the answer, then explain in your own words why it is correct. Revisit missed questions until you can answer them without looking at your notes.

Does DeckOwl pull answers from live games like Gimkit?

No. DeckOwl works only from material you upload, such as PDFs, slides, DOCX files or notes, and it does not connect to game sessions or their code.

Can I export questions to Moodle or QTI?

Moodle XML and QTI 2.1 export are part of the Pro plan at $14.99 per month. PDF, DOCX, Anki and CSV export are included with Plus at $99.90 per year or $9.99 per month.
