You are a doctor. The sentence is a patient. Your job is to find what is wrong and fix it — or confirm the patient is healthy. --- KEY RULES / PROPERTIES Rule 1 — Subject-Verb Agreement The verb must match the subject in number (singular/plural)
'The group of students ARE going' is wrong. 'The group of students IS going' is correct. A collective noun like 'group' takes a singular verb. Rule 2 — Tense Consistency Do not mix tenses without reason. If a sentence starts in past tense, it should stay in past tense
'She went to market and buys vegetables' is wrong. Both actions are in the past, so: 'She went to market and bought vegetables.' Rule 3 — Correct Use of Articles (A, An, The) Use 'A' before consonant sounds, 'An' before vowel sounds. Trap: 'An university' is WRONG. 'University' sounds like 'Yoo-niversity' (consonant sound), so: 'A university.' Rule 4 — Preposition Usage Each verb has a fixed preposition partner. Learn common pairs
'Interested IN,' 'Afraid OF,' 'Married TO,' 'Consist OF.' Rule 5 — Correct Pronoun Usage Pronoun must match its antecedent (the noun it refers to) in gender and number
'Everyone must bring their book' — 'their' is now acceptable for 'everyone' in modern grammar. Rule 6 — Correct Degree of Adjective Do not use double comparatives or superlatives. 'More better' is WRONG. 'Better' is already comparative. Use only 'better.' 'Most tallest' is WRONG. Use 'tallest.' Rule 7 — Parallelism Items in a list must have the same grammatical form
'She likes singing, to dance, and read.' Right: 'She likes singing, dancing, and reading.' ---
(Memorise These Patterns)
Formula 1 — Collective Noun Rule:
Collective Noun (Army, Team, Committee, Family) + Singular Verb
Formula 2 — Double Comparative Rule:
Never use 'more' or 'most' with -er or -est forms.
Formula 3 — Preposition with 'Married':
Formula 4 — 'Since' vs 'For':

— HOW SSC CGL ASKS THIS SSC CGL typically gives 4-5 Sentence Improvement questions per paper. The underlined part is usually: - A verb (testing tense or subject-verb agreement) - A preposition (testing fixed prepositions) - An adjective or adverb (testing degrees of comparison) - An article (A/An/The errors) - A pronoun (testing case or number) ---
Read the word ALOUD. If it starts with a VOWEL SOUND → An. If CONSONANT SOUND → A. 'An hour' (H is silent, sounds like 'our') — CORRECT. 'A honest man' — WRONG. 'Honest' sounds like 'On-est.' Use 'An honest man.' Trick 2 — Eliminate Obvious Wrongs First: In 4 options, usually 2 are clearly wrong. Focus on the remaining 2 and compare them.
This saves 30-40 seconds per question
Whenever you see a list in the sentence, check that ALL items end in the same form (-ing, -ed, to+verb, etc.). If one breaks the pattern, that is your error. ---
Identify the issue. 'Since' is used with a point in time. 'Five years' is a PERIOD of time.
Apply Formula 4. Period of time → use 'FOR.'
Check all options. Option A says 'for five years.' This is correct.
Eliminate B ('from' is wrong here) and C ('since five year' is still wrong). Answer: A) for five years WORKED EXAMPLE 2 Sentence: 'The committee have decided to postpone the meeting.' Underlined: 'have decided' Options: A) has decided B) are deciding C) were deciding D) No Improvement
Identify the subject. Subject = 'The committee' — a collective noun.
Apply Formula 1. Collective noun acting as one unit → singular verb.
'have decided' is plural. It should be 'has decided.'
Option A = 'has decided.' This is correct. Answer: A) has decided ---
— THE #1 TRAP Students choose 'No Improvement' too quickly. They read the sentence fast, feel it sounds correct, and pick 'No Improvement' without checking the grammar. This is the most dangerous habit. FIX: Always test subject-verb agreement AND tense consistency before selecting 'No Improvement.' Only pick it after ruling out all errors deliberately.
