Key Points at a Glance
- 1
Error-spotting method: find the subject and finite verb first, then check tense, article, pronoun reference, preposition, modifier, and idiom in that order.
- 2
Subject-verb agreement: a singular subject takes a singular verb and a plural subject takes a plural verb; ignore interrupting phrases such as "of the candidates".
- 3
Tense rule: use simple past with a finished past time such as "yesterday"; use present perfect when the time is unfinished or the result matters now.
- 4
Article rule: use "a" before a consonant sound, "an" before a vowel sound, and "the" for a specific, unique, previously mentioned, or superlative noun.
- 5
Sentence improvement test: the best option must be grammatically correct, clear, economical, and faithful to the original meaning; the shortest option is not always best.
- 6
Idiom warning: fixed patterns must remain fixed, such as "prefer X to Y", "different from", "accused of", "superior to", and "discuss the matter".
- 7
Word-usage check: distinguish close words by function and meaning, such as "affect" as a verb, "effect" as a noun, "fewer" for countable nouns, and "less" for uncountable nouns.
- 8
Official letter format: use sender's address, date, receiver's designation and address, subject, salutation, body, complimentary close, signature, and name in that order.
- 9
Voice questions require identifying whether the subject performs the action or receives it; passive forms use an appropriate form of be plus the past participle.
- 10
Narration questions require changes in reporting verb, pronoun, tense, time expression, word order in questions, and imperative structure according to meaning.
- 11
Translation, comprehension, synonyms, antonyms, one-word substitution, and official-technical glossary questions test exact meaning in context, not decorative vocabulary.
- 12
Letter-writing questions cover official, demi-official, and informal formats; objective questions may test order, salutation, subject line, tone, and closing.

What this topic tests in CET
Spotting errors, sentence improvement, and word usage test practical command of standard English. The question is usually not about rare grammar labels. It asks whether a candidate can see how a sentence is built, identify the part that breaks standard usage, and choose a correction that keeps the intended meaning intact. At CET Graduation level, the range is broader than school-level grammar: agreement, tense sequence, articles, prepositions, pronouns, conjunctions, modifiers, idioms, vocabulary precision, redundancy, and formal sentence style can all appear.
The safest reading habit is to treat every sentence as a complete unit. A sentence may contain a familiar word but a wrong relationship. "The quality of the answers were poor" sounds ordinary until the real subject is identified. The subject is "quality", so the corrected form is "The quality of the answers was poor." Similarly, "He discussed about the issue" is wrong because "discuss" takes a direct object; the correction is "He discussed the issue." CET questions often reward this kind of steady checking rather than advanced theory.
Core focus: do not rely only on what sounds familiar; test the sentence by rule, meaning, and standard usage.
