What are Sentence Correction CAT Questions?

Sentence Correction CAT questions in the Common Admission Test (CAT) exam are a type of question in the Verbal Ability section that test a candidate's proficiency in English grammar, usage, and style.

The primary objective is to evaluate your ability to identify and correct grammatical errors, awkward phrasing, and logical inconsistencies in a given sentence, choosing the option that expresses the intended meaning in the most clear, concise, and grammatically correct manner.

The most common format for Sentence Correction CAT questions is:

• A sentence is presented, and a part of it (sometimes the entire sentence) is underlined or bolded.
• Multiple-choice options (usually four or five) are provided. These options offer different ways of rephrasing the underlined/bolded fragment.
• Your task is to select the option that best corrects any errors in the original fragment. One of the options may be the original sentence itself, indicating "No correction required."

Tips to Solve Sentence Correction CAT Questions 2025

1. Identify the Core Sentence and Error:

• Strip the Sentence: Immediately find the subject and verb of the main clause. Temporarily ignore all prepositional phrases, modifiers, and non-essential clauses (like those set off by commas). This helps you quickly spot basic errors like Subject-Verb Agreement.
• Look for Splits: Analyse the differences (the "splits") between the options. They usually target a specific grammatical rule (e.g., tense, pronoun, parallelism). If one option uses a plural verb and others use a singular verb, focus on Subject-Verb Agreement.

2. Focus on the Big Three

• Parallelism: Check for lists, comparisons, and correlative conjunctions (e.g., not only... but also, either... or). The structures on both sides must be identical.
• Modifiers: Ensure all modifiers (adjectives, adverbs, phrases) are placed as close as possible to the word they are intended to modify to avoid dangling or misplaced modifiers.
• Subject-Verb Agreement: Make sure the verb matches the actual subject in number (singular or plural), especially when words separate the subject and verb (e.g., along with, in addition to).

3. Evaluate for Meaning:

• Preserve the Intended Meaning: The correct answer must fix the grammatical error without changing the logical meaning of the original sentence.
• Choose Concise: Between two grammatically correct options, the shorter, more direct, and less wordy answer (the most concise one) is often the preferred choice. Eliminate options that are redundant (e.g., return, annual birthday).

4. Master Idioms and Diction

• Memorise common tricky idioms and prepositional phrases (e.g., distinguish between X and Y, committed to [gerund]).
• Be aware of commonly confused diction (word choice) pairs (e.g., affect vs. effect, less vs. fewer).

Mistakes to Avoid while Solving Sentence Correction CAT Questions 2025

1. Ignoring the Non-Underlined Part

Never assume the non-underlined part is correct. The error in the underlined part might be caused by an incompatibility with the non-underlined part (e.g., a time marker like "Since 1990" in the non-underlined part demands a perfect tense in the underlined part).

2. Relying on "Sounding Right"

SC is a test of formal, prescriptive grammar, not conversational fluency. Many grammatically incorrect structures "sound fine" to a native speaker. You must rely strictly on grammatical rules, not intuition.

3. Comparing Options to Each Other

Your only job is to compare the underlined part (and its alternatives) against the full, intended meaning of the original sentence, checking for errors. Don't simply compare Option A to Option B; compare Option A to the original sentence, Option B to the original sentence, and so on.

4. Making Unnecessary Changes

Your goal is to fix what is broken. Avoid choosing an option that introduces a new, more complex, or redundant structure when a simple, direct option is available.

5. Confusing Like and As:

Use like to compare nouns or noun phrases: He swims like a fish.

Use as to compare clauses (with a verb): He swims as he was taught.

Conclusion

Sentence Correction CAT Questions 2025 is fundamentally a test of your knowledge of formal English grammar. Success in this area is achieved through consistent practice aimed at diagnosing the specific error (parallelism, S-V agreement, modifier placement) before rushing to the options.

By focusing on the core structure, conciseness, and eliminating common mistakes, you can significantly improve your accuracy in the Verbal Ability section of all major management entrance exams.
