Sentence Improvement

Overview

Sentence Improvement is a staple of the IBPS PO Prelims English section, typically contributing 5 questions per exam. The format is straightforward: a sentence contains an underlined portion, and you must decide whether that portion is grammatically correct or should be replaced with one of the given alternatives. One option is always "No improvement required" or "No correction required."

This topic tests your command of grammar rules, idiomatic usage, and standard English expression. Unlike Error Spotting where you only identify the mistake, here you must select the best replacement—making it a test of both detection and correction skills. Mastering this topic requires familiarity with common grammatical structures: subject-verb agreement, tense consistency, correct preposition usage, parallel construction, and proper idiomatic expressions.

The good news is that Sentence Improvement questions are highly pattern-based. The same error types recur across exams, and once you recognize these patterns, you can solve questions in under 30 seconds each.

Key Concepts

• **Subject-Verb Agreement**: The verb must match the subject in number (singular/plural). Intervening phrases between subject and verb often create confusion.

• **Tense Consistency**: A sentence should maintain logical tense flow. Random shifts between past, present, and future tenses are incorrect unless the meaning demands it.
