Why a custom quiz beats a generic one

Adults looking for a grammar quiz for adults with answers often find generic worksheets that cover rules they already know and skip the ones they struggle with. A quiz built from your own notes or assigned reading targets the exact constructions you are working on, such as agreement, pronoun case or conditionals.

  • Multiple-choice, true/false and short-answer questions with explanations
  • Free plan includes 3 generations per month and in-browser study
  • Plus and Pro unlock exports for PDF, DOCX, and in Pro, QTI 2.1 and Moodle XML
Example grammar practice questions with answers
Choose the correct verb: 'The team ___ voted to approve the budget.' (has / have)has. 'Team' is a collective noun that takes a singular verb in American usage, since the group acts as one unit.
Which sentence is correct? (a) 'To who should I address this?' (b) 'To whom should I address this?'(b). 'Whom' is the object of the preposition 'to', so the objective form is required.
True or false: A dangling modifier is fixed by placing the modifier next to the word it describes.True. 'Walking home, the rain soaked me' becomes 'Walking home, I was soaked by the rain' because the walker must be the subject.
Fill in the blank: 'If I ___ you, I would apply for the scholarship.'were. The subjunctive mood is used for hypothetical conditions that are contrary to fact.
Rewrite correctly: 'Each of the students have a pen.'Each of the students has a pen. 'Each' is singular, so the verb must agree with it rather than with the plural noun 'students'.

Questions from your material

Upload a PDF, slides, a DOCX file, plain notes or a photo of a page, and the quiz is built from what you wrote or were assigned.

Answers and explanations

Each question comes with the correct answer and a short explanation of the grammar rule behind it, so you learn from misses.

Study in the browser or export

Take the quiz on the free plan in your browser. Plus adds PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML.

How it works

Upload your grammar source

Add the handout, lesson notes, textbook chapter or slides you want to test yourself on.

Choose the question type

Pick multiple choice, true/false or short answer, depending on whether you want recognition or recall practice.

Take the quiz and check answers

Answer each question, read the explanation for anything you missed, and retake the questions you got wrong.

Answers matter most when they explain the rule. DeckOwl writes an explanation with each question, so a wrong answer becomes a short lesson rather than a dead end. Retaking only the questions you missed keeps practice focused.

If you need to share or report results, the Plus plan exports to PDF and DOCX, and Pro adds QTI 2.1 and Moodle XML for learning management systems.

Frequently asked questions

How do adults review grammar most effectively?

Short, frequent quizzes on the specific rules you find hard work better than long reviews of everything. Reading each explanation after answering helps the rule stick.

Which grammar topics should an adult quiz cover first?

Start with the errors you make most in your own writing, such as subject-verb agreement, who versus whom, and comma placement. Then move to less common structures like the subjunctive mood.

Is there a free plan?

Yes. The free plan includes 3 generations per month and lets you study in the browser. No credit card is needed to start.

Can I export the quiz?

Exports are paid features. Plus includes PDF, DOCX, Anki and CSV export for $39/year or $7.99/month, and Pro adds QTI 2.1 and Moodle XML at $14.99/month.
