English grammar: practice, test and prove it
Tenses, subject-verb agreement, articles and prepositions as they appear in workplace English.
Grammar screenings for customer-facing roles are usually short multiple-choice rounds. You read a sentence from an email, chat or call note and pick the correct word or find the error. The focus is on mistakes that make written replies look careless: the wrong tense, a verb that does not match its subject, a missing article or the wrong preposition.
This page gives you 15 practice questions in that format, two lessons on the rules that are tested most often, and interview questions about checking your own writing. Each answer explains the rule, so you can fix the pattern and not just one question.
Benchmark: The pass mark on this site is 80%; grammar is commonly screened for customer support, BPO, sales and other customer-facing roles. Requirements vary by employer.

Common questions
Is this test based on British or American English?
The questions avoid points where British and American usage differ, such as spelling or collective nouns. Rules on tense, agreement and articles are the same in both.
How long should I spend on each question?
Many timed screenings allow less than a minute per question. If you are unsure, remove the options that are clearly wrong and choose from the rest.
Does grammar matter if the job is mostly voice calls?
Yes. Voice agents still write call notes, emails and chat replies, and many hiring processes include a written round before the voice round.
