Frequently Asked Questions

Subject-verb agreement is a grammatical rule that requires the verb to match its subject in number (singular or plural) and person (first, second, or third). For example: "He runs" (singular) vs. "They run" (plural).

Beginners should start with Multiple Choice mode at Easy difficulty. Intermediate learners can try True/False mode at Medium difficulty. Advanced learners can challenge themselves with Fix the Sentence mode at Hard difficulty.

How can teachers use this in classrooms?

Teachers can use this tool for: warm-up activities, grammar stations, homework assignments, test preparation, and identifying common student errors. The different modes allow for differentiated instruction.

What do my scores mean?

Are there any limitations to this tool?

This tool focuses specifically on subject-verb agreement and doesn't cover all grammar aspects. Automated evaluation cannot replace human feedback for nuanced language use. Always consult grammar references for complex cases.

How often should I practice?

For optimal learning, practice 10-15 minutes daily or 30 minutes 2-3 times per week. Regular short sessions are more effective than occasional long sessions.

Common Learner Mistakes & Tips

Top 5 Common Errors:
  1. Intervening phrases: "The box of pencils are heavy" → should be is
  2. Indefinite pronouns: "Everyone have their book" → should be has
  3. Collective nouns: "The team are winning" → usually is in American English
  4. Compound subjects: "Bread and butter are my favorite" → often is when expressing a unit
  5. There is/are: "There is many reasons" → should be are with plural subject

Tip: Always identify the true subject by asking "Who or what is doing the action?" Ignore prepositional phrases between subject and verb.
