Why a custom grammar quiz beats a generic one

When a grammar lesson ends, the fastest check is a grammar quiz built from that same lesson's rules and examples. A ready-made quiz covers someone else's sentences, so it often misses the exact comma rule or verb agreement pattern your teacher covered.

  • Questions drawn only from your lesson material
  • Explanations that name the grammar rule behind each answer
  • Free plan includes 3 generations per month, studied in the browser
  • Plus adds unlimited generations and PDF or DOCX export
Example grammar quiz questions
Which is correct: 'Neither the manager nor the staff members were ready' or 'Neither the manager nor the staff members was ready'?The first one, with 'were'. With 'neither...nor', the verb agrees with the closer subject, here the plural 'staff members'.
Which sentence punctuates correctly: 'After the test we went home' or 'After the test, we went home'?The second, with the comma. An introductory phrase like 'After the test' is set off from the main clause by a comma.
Fill in the blank: 'Each of the candidates ___ a copy of the form.''has'. 'Each' is singular, so the verb must be singular even though 'candidates' is plural.
Choose the correct word: 'The new rule will ___ grades.' (affect or effect)'affect'. As a verb, 'affect' means to influence, while 'effect' as a verb means to bring about.
Identify the error: 'Between you and I, the plan works.''Between you and me'. 'Between' is a preposition, so it takes the object pronoun 'me', not the subject pronoun 'I'.

Frequently asked questions

What grammar topics work best for a quiz?

Rule-based topics such as subject-verb agreement, comma use, pronoun case and commonly confused words work well because each question has one clear correct answer. Vague topics like writing style produce answers that are hard to grade.

How many questions should a grammar quiz have?

Ten to fifteen questions covers one lesson without making the session feel long. Mix question types so multiple choice checks recognition and short open answers check production.

Is the grammar quiz free to use?

The free plan gives 3 generations per month and lets you study in the browser, but exports are not included. Plus, at $99.90/year or $9.99/month, adds unlimited generations and PDF, DOCX, Anki and CSV export.

Can I export the quiz to Moodle?

Moodle XML and QTI 2.1 export are on the Pro plan at $14.99/month. Plus covers PDF and DOCX export if you need a printable or shareable file.
