How a code quiz maker fits into studying programming

A code quiz maker works best when it reads your own material, so the questions match the syntax, concepts and examples your course actually covers.

Turn lecture slides on data structures or Python basics into quizzes in a few minutes.
Check syntax recall with true/false items that target common mistakes.
Write short-answer questions that ask you to explain behavior, not just memorize it.
Review explanations after each attempt to see why an answer was wrong.

Example Python and JavaScript programming quiz questions

In Python, what does range(2, 8, 2) produce?[2, 4, 6]. The stop value 8 is excluded, and the step of 2 gives every second number.

Are Python lists or tuples mutable?Lists are mutable and tuples are immutable, so you can change a list's elements after creating it but not a tuple's.

What is the time complexity of binary search on a sorted array?O(log n). Each comparison halves the remaining search range, so the number of steps grows logarithmically.

Why does a recursive function need a base case?Without one, every call makes another call and the recursion never stops, which eventually causes a stack overflow.

What does typeof null return in JavaScript?The string "object". This is a long-standing quirk from early JavaScript that cannot be changed without breaking existing code.

Generate the full set

Questions from your own code material

Upload slides, notes or PDFs covering syntax, algorithms or debugging, and get questions drawn from what your course actually teaches.

Multiple-choice, true/false and short answer

Mix question formats in one quiz so you can check recognition of syntax and also explain concepts in your own words.

Explanations for every answer

Each question includes a short explanation of why the correct answer is right, so a wrong guess becomes a lesson.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, plain text file or a photo of your notes. Photos are read with text recognition.

Choose a question type

Pick multiple-choice, true/false or short answer, or combine them in one quiz.

Study and export

Take the quiz in your browser. Paid plans can export to PDF, DOCX, QTI 2.1 or Moodle XML.

Programming quizzes test different skills at once. Multiple-choice questions check whether you recognize a language feature, while short-answer questions ask you to explain what a function returns or why a loop terminates. Writing both kinds of question from the same lecture gives you a more complete check than rereading slides.

Generated quizzes are most useful when you retake them over several days. Missed questions and their explanations show you which concepts need another pass before an exam or a coding assessment.

Frequently asked questions

How many quiz questions should I make for a programming unit?

Start with 10 to 15 questions per lecture or chapter so each topic gets several checks. Focus first on concepts you find confusing, such as recursion, pointers or asynchronous code, and add more questions there.

How do I study code by quizzing myself?

Answer each question by reasoning about what the code does before you look at the explanation. Retake missed questions after a day or two, since spacing your practice improves recall better than one long session.

Is there a free plan for the code quiz maker?

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

Which formats can I export quizzes to?

Plus includes PDF and DOCX export. Pro adds QTI 2.1 and Moodle XML, which work with many learning management systems.
