Why build a kelas X quiz from your own material

Many students in a kelas X course start with a ready-made quiz, but a generic set rarely matches what the teacher covered this week. DeckOwl works the other way around: you upload the slides, notes or textbook pages your class is using, and it writes questions from that exact content. Each answer comes with a short explanation, so the quiz also works as a review of the lesson.

  • Questions are generated only from the files you upload.
  • Multiple choice, true/false and open questions, each with an explanation.
  • Free plan: 3 generations per month, study in the browser.
  • Students get 40% off with a school email, and no credit card is needed to start.
Example Biology quiz questions for kelas X (grade 10)
Which organelle is the main site of aerobic respiration in a eukaryotic cell?The mitochondrion. It converts glucose and oxygen into ATP, the energy the cell uses.
True or false: plant cells have a cell wall made mainly of cellulose.True. The cellulose wall gives plant cells rigid support and their shape.
Why is the cell membrane described as selectively permeable?Its phospholipid bilayer lets small nonpolar molecules pass easily, while large or charged molecules need channel or carrier proteins.
What is the main function of the nucleus in a cell?It stores DNA and controls gene expression, which directs protein synthesis and cell activity.
In osmosis, which way does water move across a membrane?From the side with lower solute concentration to the side with higher solute concentration, because water follows its own concentration gradient.

Built from your material

Questions come from the PDF, DOCX, PPTX, text or photo of pages you upload, not from a generic question bank.

Three question types

Choose multiple choice, true/false or open questions. Every answer includes an explanation of why it is correct.

Export when you need it

Plus adds PDF, DOCX, Anki and CSV export. Pro adds QTI 2.1 and Moodle XML for school learning systems.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, text file or photo of a page from your kelas X lesson.

Pick a question type

Select multiple choice, true/false or open questions and set how many you want to practice.

Practice and review

Answer in the browser, read each explanation, and retry the questions you missed.

Start with a short quiz after each topic rather than one long test at the end. Attempt every question before reading the explanation, then return to the missed ones a few days later. Free accounts get 3 generations per month and can study in the browser. Plus and Pro add exports for printing, sharing with a teacher, or moving questions into another learning system.

Frequently asked questions

How many questions should a kelas X quiz have?

For a single topic, 10 to 20 questions usually covers the main ideas without becoming tiring. Use a shorter set for quick daily review and a longer one before a unit test.

How should a grade 10 student study with a quiz?

Answer each question before checking the explanation, then write down the reason for every wrong answer. Retry the missed questions after a few days to move the facts into longer-term memory.

Can I export the quiz to share or print?

PDF, DOCX, Anki and CSV export are included on Plus, at $99.90/year or $9.99/month. QTI 2.1 and Moodle XML export are on Pro, at $14.99/month.

Do I need a credit card to start?

No. The free plan gives you 3 generations per month and studying in the browser, and you can upgrade later if you need exports or unlimited generations.
