Why generate grammar quiz questions from your own material
Most ready-made grammar worksheets cover rules your class has not reached yet, so their answers rarely match what you studied. English grammar quiz questions and answers work best when they come from your own lesson material, such as verb tense charts, a unit on subject-verb agreement or a slide deck on comma rules. DeckOwl reads PDFs, DOCX and PPTX files, text notes and photos of pages, then writes questions with an explanation for each correct answer.
- Questions follow the grammar units in your own notes or slides.
- Explanations name the rule behind each correct answer.
- Short-answer questions ask you to correct a sentence in your own words.
- Free plan studies in the browser; exports need a paid plan.
Multiple choice, true/false and short answer
Mix question types so you practice recognizing errors and writing corrections yourself.
An explanation for every answer
Each correct answer comes with a short reason, so you learn the rule and not just the letter.
Built from your own material
Questions come from the lessons you actually studied, not a generic worksheet from the internet.
How it works
Upload your notes
Add a PDF, DOCX, PPTX, plain text file or a photo of a page.
Choose a question type
Pick multiple choice, true/false or short answer and set how many questions you want.
Practice and review
Answer in the browser, then read the explanations for every question you missed.
Printed or downloaded quiz pages are handy for a quick warm-up, but they cannot show which errors you repeat. When the questions come from your own notes, the quiz stays on the rules you covered, and each explanation points back to the sentence pattern that matters. Review the wrong answers first, since the explanation usually names the rule you missed.

Frequently asked questions
How do I check subject-verb agreement in a long sentence?
Find the true subject first and ignore phrases between it and the verb, such as prepositional phrases. Then match the verb to that subject's number, singular or plural.
How many grammar questions should I practice in one sitting?
A focused set of about 20 questions on one rule is a good session size. Short sessions spread over several days usually help more than one long review the night before a test.
Can I export these quizzes to Moodle or QTI?
Moodle XML and QTI 2.1 export are part of the Pro plan at $14.99 per month. The Plus plan at $39 per year or $7.99 per month includes PDF and DOCX export.
Is there a free plan?
Yes. The free plan includes 3 generations per month and studying in the browser, but exports are not included. Students with a school email get 40% off, and no credit card is needed to start.
