Why a custom grammar quiz beats a generic one
Printable grammar quizzes are easy to find, but they rarely match the mistakes you actually make. A grammar quiz for adults works best when it targets your own weak spots, such as agreement, pronoun case or verb mood.
- Subject-verb agreement with collective nouns and compound subjects
- Pronoun case after prepositions and in compound phrases
- Verb tense and mood, including conditionals and the subjunctive
- Modifier placement and sentence structure errors
Three question types
Multiple choice, true/false and open questions, each with an explanation for the answer.
Built from your material
Works from PDFs, DOCX, PPTX, plain text and photos of pages read with text recognition.
Export when you need it
Plus exports to PDF and DOCX. Pro adds QTI 2.1 and Moodle XML for course platforms.
How it works
Upload your material
Add a PDF, slides, a Word file, notes or a photo of a page.
Choose the question type
Pick multiple choice, true/false or short answer questions.
Take the quiz
Work through it in the browser, then read the explanation for each answer.
DeckOwl reads the material you already have, whether that is a style guide, a course handout or your own writing notes, and writes questions that test those specific rules. Each wrong answer comes with an explanation, so the quiz teaches as you go.

Frequently asked questions
How many questions should a grammar quiz for adults have?
Around 10 to 20 questions per session works well for most adults, which is enough to test several rules without fatigue. Repeat the quiz after a few days to check what actually stuck.
How should I study grammar rules I keep getting wrong?
Focus on one rule at a time, explain why the correct form works in your own words, and retest after a day or two. Missed questions are the ones to review most often.
Can I export a quiz to use in a course?
PDF and DOCX export are included in Plus, and QTI 2.1 and Moodle XML export are available on Pro. The free plan lets you study in the browser without exports.
Do I need a credit card to try it?
No. You can start on the free plan with three generations per month, and students get 40% off with a school email.
