How a vocabulary and grammar quiz app helps you study

Word meanings and grammar rules fade fast when you only reread them, but they stick when you have to pick the right answer. A vocabulary and grammar quiz app turns your own word lists and rule summaries into practice questions, so you test recall on the exact material your teacher assigned.

Quiz on word meanings, roots and prefixes using your own vocabulary list
Practice verb tense, agreement and pronoun rules with questions based on your notes
Repeat missed questions in short sessions instead of rereading the whole chapter
Turn a grammar handout into both a quiz and a set of flashcards

Example vocabulary and grammar quiz questions

Which word means 'lasting only a short time'? (a) ephemeral (b) perennial (c) verbose (d) tenaciousEphemeral. It comes from Greek roots meaning 'lasting a day', so it describes something brief.

Choose the correct form: 'If I ___ you, I would apologize.' (a) was (b) wereWere. The subjunctive is used for hypothetical conditions with 'if', even when the subject is 'I'.

True or false: 'Between you and I' is correct after a preposition.False. After prepositions such as between, use object pronouns, so the correct phrase is 'between you and me'.

Which is correct: 'Neither the teacher nor the students were ready' or 'Neither the teacher nor the students was ready'?Were. With neither...nor, the verb agrees with the nearer subject, which here is 'students'.

What does the prefix 'mis-' mean in 'misjudge'?Wrongly or badly. Prefixes like mis- change the meaning of a base word, so misjudge means to judge wrongly.

Generate the full set

Questions from your material

Vocabulary lists, grammar handouts and textbook chapters become quiz questions that match what you actually need to learn.

Explanations for every answer

Each question includes a short explanation, so a wrong answer about verb agreement or word roots teaches you the rule.

Flashcards and mind maps too

Switch to spaced-repetition flashcards for word recall or a mind map that groups grammar rules by topic.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, plain text file or a photo of a page. Photos are read with text recognition.

Choose question types

Pick multiple choice, true/false or short answer. Start with a small set of words or rules and expand from there.

Quiz yourself and review

Answer in the browser, read each explanation, and repeat the questions you missed until the rules stick.

Good grammar practice mixes question types. Multiple choice checks whether you can spot the correct verb form, true/false catches common misconceptions like 'between you and I', and short-answer questions force you to explain a rule in your own words. Read the explanation after every miss, since that is where the rule is usually learned.

DeckOwl runs in the browser on the Free plan, which includes 3 generations per month. Plus and Pro add unlimited generations and file exports for printing or sharing.
