Grammar Basics for the KET Exam — Mexican candidates
10% of the KET test plan. A2-level grammar: present simple/continuous, past simple, basic modals, articles, and prepositions. Calibrated for Mexican candidates.
For candidates aiming to clear this exam on the first attempt, the difference between Band 6 and Band 7+ — or "passing" and "comfortable margin" — usually comes down to fluency on a small number of high-leverage topics. Grammar Basics sits at roughly 10% of the Cambridge Key English Test (A2) content distribution — Grammar underlies all four A2 Key skills. Common A2 grammar points include: verb tenses (present simple, past simple, present continuous), modals (can, could, should, would), prepositions of place and time, articles (a/an/the), and question formation. Errors in these basic structures drop scores significantly. Pass rates for the KET are published annually by the awarding body and vary by cohort and locale. For Mexican candidates preparing for KET, the calibration of study to local context matters: Spanish is the testing language for domestic exams (Ceneval); English-language proficiency tests (TOEFL, IELTS, Cambridge) are popular for U.S. and Canadian study tracks.
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.
- !Confusing present simple and present continuous for habitual vs current actions
- !Missing the third-person singular -s (he go → he goes)
- !Article errors: using "a" before vowel sounds, missing "the" for specific nouns
Study tips
- 1Drill the present simple/continuous contrast daily: "I walk to school" (habit) vs "I am walking" (now).
- 2Memorize the irregular past tenses: go → went, have → had, buy → bought, see → saw.
- 3Practice the difference between a/an (first mention, general) and the (known, specific, second mention).
- 4For Mexican candidates testing on KET, English-Spanish bilingual study materials accelerate vocabulary acquisition; use side-by-side passage translations to build decoding speed.
