Advanced B1 Grammar Structures for the PET Exam — U.S. candidates

10% of the PET test plan. B1 grammar extension: modals for deduction, wish/if only, gerunds vs infinitives, and comparatives. Calibrated for American candidates.

Most exam coaching covers the curriculum at the same depth across all topics. That misses the asymmetry of high-stakes testing: a few topics carry disproportionate weight on the score. Advanced B1 Grammar Structures sits at roughly 10% of the Cambridge Preliminary English Test (B1) content distribution — Advanced B1 grammar structures include: modals for deduction (must be/can't be/might be), wish/if only (unreal situations), gerund vs infinitive choice (enjoy doing/want to do), and comparative/superlative structures. These features distinguish B1 from A2 performance. Pass rates for the PET are published annually by the awarding body and vary by cohort and locale. For U.S. candidates preparing for PET, the calibration of study to local context matters: U.S. licensure exams are governed at the state level (CDL, NCLEX) or by national boards (MCAT, GRE). Pearson VUE and PSI are the dominant test-delivery vendors.

Pass rates for PET (United States) are published periodically by the awarding body.

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

  • !Using "must" for deduction and "have to" interchangeably — they have different strength
  • !Gerund/infinitive errors: "I enjoy to swim" instead of "I enjoy swimming"
  • !Incorrect comparative: "more better" instead of "better"

Study tips

  • 1Memorize the 20 most common gerund-taking verbs: enjoy, finish, avoid, consider, suggest, mind, miss, keep, risk, practise.
  • 2Learn the 20 most common infinitive-taking verbs: want, need, hope, plan, decide, agree, refuse, manage, offer, seem.
  • 3Drill deduction modals: must = I'm almost certain; might = possible; can't = impossible.
  • 4If you are testing in the U.S., expect PET delivery via Pearson VUE or PSI test centres — register through the official board portal at least 30 days in advance.

    She left the office early. She _____ be feeling unwell.

    • AmustCorrect
    • Bcan
    • Cshould
    • Dwould
    Why this answer?

    "Must be feeling" expresses logical deduction — the speaker is almost certain she is unwell based on evidence (leaving early). "Can" is not used for deduction; "should" implies expectation/advice; "would" implies a hypothesis about the future.
