291 words, about 1 min05General English: Grammar Accuracy and Vocabulary
General English in CEPTAM STA-B Tier-I checks correctness rather than literary flair: error spotting, sentence correction, fill in the blanks, subject–verb agreement, tenses, articles and prepositions, active–passive voice, direct–indirect speech, synonyms, antonyms, idioms, one-word substitutions, spellings, para jumbles and a short comprehension passage. The verb agrees with the subject, not with the nearest noun: "The quality of the mangoes was poor." "One of + plural noun" takes a singular verb: "One of the boys is absent." Collective nouns (team, jury, committee) take a singular verb when acting as one unit.
