Open source study topics, quizzed from your own material

Many people who want an open source online quiz maker care most about owning their study material and reusing it outside a single platform.

Generate questions from your own lecture slides, readings or notes.
Check each answer against its explanation before you rely on it.
Repeat missed questions until you can answer them without looking.
Export to Moodle XML or QTI 2.1 on Pro if your course uses those systems.

Example open source license and concept questions

What are the four freedoms in the Free Software Definition?The freedom to run the program for any purpose, study and change it, redistribute copies, and distribute modified versions. These freedoms are what make access to source code meaningful.

True or false: an open source license must be free of charge.False. The Open Source Definition allows commercial redistribution, so software can be sold as long as the license permits source access, modification and redistribution.

What does a copyleft license such as the GPL require?Distributed modified versions must be released under the same license. This keeps improvements open instead of letting them become closed software.

What is a fork in open source development?An independent copy of a project's source code that is developed separately. Open licenses permit it because they allow copying and modification.

Name one difference between permissive and copyleft licenses.Permissive licenses like MIT allow derivative works to be closed, while copyleft licenses like the GPL require derivative distributions to stay open under the same terms.

How it works

Choose question types

Pick multiple-choice, true/false or short-answer questions, and generate a set built from your own content.

Study or export

Work through the quiz in the browser, or export it if your plan includes that format.

DeckOwl runs in the browser and turns your PDFs, DOCX and PPTX files, plain notes or photos of pages into quizzes. The free plan includes three generations per month, while PDF, DOCX, Anki and CSV export are part of Plus, and QTI 2.1 and Moodle XML export are part of Pro.

Quizzes work best when the questions come from the exact readings, lecture slides or notes you need to learn, so the generator builds each set from what you upload.

Frequently asked questions

What should I study to understand open source licenses?

Start with the main families: permissive licenses such as MIT, BSD and Apache 2.0, and copyleft licenses such as the GPL. Quiz yourself on what each one requires when you redistribute code.

How many questions should a quiz on open source basics have?

Around 10 to 20 questions is a common range for one topic. Mix true/false with short-answer items so you practice recall rather than just recognizing the right option.

Can I export my quiz to Moodle?

Yes, but only on the Pro plan, which includes QTI 2.1 and Moodle XML export. The free plan lets you study in the browser, and Plus adds PDF, DOCX, Anki and CSV export.

Does DeckOwl need a credit card to start?

No. You can start without a credit card, and students get 40% off with a school email.
