B1 Diagnostic — Find the Grammar Errors

Welcome to Grammar Detective! Your mission: find grammar errors hidden in natural paragraphs.

For each case, you will:

  • Read a short paragraph for context
  • Examine individual sentences or fragments from that paragraph
  • Decide: "Correct as written" or "Has an error"
  • Get instant feedback and track your progress

Ready? Let's begin with a practice case.

Practice Case: Learning to Observe

Context
Sarah is learning to cook Italian food. She has been attending cooking classes since two weeks now. Her teacher recommended her to practice at home. If she would improve her skills, she might enter a cooking competition.

You have 4 cases to investigate. Each case contains fragments to evaluate. Take your time. Your goal: spot every error correctly.

Here's a complete review of all the errors in the investigation. Study the patterns, and you'll notice how grammar works.
