Read the requested construction before choosing a form.
Review six selected checks: present-simple agreement, a past question, plural be, a non-defining relative clause, want with an infinitive and enjoy with an -ing form.
Each of six items counts one matching answer. Your count describes these tasks under your practice conditions, not a CEFR level, percentile, school grade or job-readiness judgement. Every worked answer and this complete guide remain available at every count.
Six specified constructions
The items ask for standard written forms in explicitly stated contexts. A singular routine subject takes a present-simple ending; a requested past-simple question uses did with the base verb. Other items check plural are, which in a comma-separated extra-information clause about a thing, wants to confirm and enjoy crossing. This is a selected review set, not coverage of all English grammar.
Change one subject and keep the time
Compare two invented statements: Every morning, Rupa checks the noticeboard; Every morning, the volunteers check the noticeboard. The routine context stays the same, while the subject changes the verb form. Now turn the second statement into a question: Do the volunteers check the noticeboard every morning? The main verb remains check after do. These are practice examples, not scored items.
Locate the part that governs the choice
For an agreement item, identify the subject before inspecting the verb ending. For a question, separate the auxiliary from the main verb. For verb patterns, inspect the first verb: enjoy and want need different following forms. Do not generalise this into a rule that every verb takes only one pattern; like and love can allow both an infinitive and an -ing form.
Rewrite before checking the answer
Choose one missed construction and write two new short sentences. Change only the subject, time context or first verb, then explain what must change and why. Compare with the relevant grammar reference after writing. If another form could also fit a different meaning, state the intended meaning explicitly. This routine is suggested practice, without a measured improvement rate or guaranteed learning time.
Recognition does not demonstrate free writing
Six visible-option decisions cannot establish overall grammar proficiency, spoken fluency or the ability to produce a complete work email. The examples use selected standard written constructions rather than ranking dialects or speakers. Repeating the same questions after seeing the keys may show recall. Use the exact explanation to choose a new exercise, not to assign yourself a fixed language level.
