When it comes to the CAT Verbal Ability & Reading Comprehension (VARC) section, Reading Comprehension often grabs the spotlight. However, many aspirants overlook a crucial area that can significantly boost their scores: Sentence Correction (SC). These questions test not just your grammar rules, but also your precision in language, clarity of thought, and ability to identify subtle logical flaws.
While SC questions might seem daunting at first, they are highly systematic. Unlike RC, where ambiguity can sometimes creep in, SC questions usually have a single, grammatically correct, logical, and concise answer. Mastering them means unlocking precious marks that can give you a significant edge in CAT 2025.
At Rahul Sir Classes, we believe that avoiding SC mistakes isn't about memorizing endless rules; it's about understanding concepts and developing a systematic approach. In this comprehensive guide, we'll break down how to identify and conquer common Sentence Correction pitfalls.

The Common Culprits: Types of SC Mistakes to Watch Out For
Before we discuss strategies, let's identify the most frequent error categories you'll encounter. Familiarizing yourself with these will help you pinpoint mistakes faster.
Subject-Verb Agreement (SVA):
The Rule: A singular subject takes a singular verb; a plural subject takes a plural verb.
Trap: Long phrases between the subject and verb, collective nouns (e.g., "committee," "team"), or indefinite pronouns (e.g., "everyone," "none").
Example: The list of items on the shelf are extensive. (Incorrect) should be is extensive.
Pronoun Errors:
Ambiguous Pronouns: When a pronoun (it, they, them, which, etc.) could refer to more than one noun.
Pronoun Agreement: A pronoun must agree in number and gender with the noun it refers to.
Pronoun Case: Using the correct case (e.g., "I" vs. "me," "who" vs. "whom").
Example: When John visited Peter, he was tired. (Ambiguous - who was tired?)
Parallelism (Parallel Construction):
The Rule: Elements in a list, comparison, or series must be in the same grammatical form (e.g., all nouns, all verbs, all gerunds).
Trap: Mixing verb forms, noun forms, or different grammatical structures.
Example: She likes hiking, swimming, and to bike. (Incorrect) should be biking.
Modifier Errors:
Dangling Modifiers: A modifier that doesn't clearly or logically modify anything in the sentence.
Misplaced Modifiers: A modifier placed incorrectly, making the sentence confusing or humorous.
Example: Running quickly, the bus was missed. (Dangling - the bus wasn't running)
Verb Tense Errors:
Inconsistent Tense: Shifting between tenses unnecessarily.
Incorrect Tense Usage: Using a tense that doesn't fit the timeline of events.
Example: She walks to the store and bought some groceries. (Incorrect) should be bought or walked.
Idiom Errors:
Incorrect Prepositions: Using the wrong preposition in an idiomatic expression (e.g., "agree with" vs. "agree to").
Incorrect Phrasing: Misusing common phrases or expressions.
Example: He is capable in doing the work. (Incorrect) should be of doing.
Redundancy and Wordiness:
Using more words than necessary to convey a meaning.
Example: She returned back home. (Redundant) should be returned home.
Rahul Sir's Systematic Approach to Conquering SC Questions
Don't just randomly pick an option! Follow this step-by-step method for consistent success:
Step 1: Read the Original Sentence Carefully for Meaning
Understand the Intent: Before looking at options, grasp what the original sentence is trying to convey. This helps you filter out options that change the intended meaning.
Identify Obvious Errors: Sometimes, a glaring error (like SVA or parallelism) will jump out immediately.
Step 2: Scan the Options for Differences
Vertical Scan: Look down the answer choices for the same position. For example, if the first word in the original is 'is' and some options have 'are', you know to check for SVA.
Identify Splits: These "splits" (differences) will often point you towards the specific grammatical rule being tested.
Step 3: Eliminate Incorrect Options Based on Rules
One Rule at a Time: Apply grammar rules rigorously. If an option violates even one rule, eliminate it.
Prioritize Common Errors: Start with SVA, Parallelism, and Pronoun errors as they are frequent and often easy to spot.
Meaning Check: If an option is grammatically correct but fundamentally changes the original meaning, eliminate it.
Step 4: Compare Remaining Options for Conciseness & Clarity
The Best Answer: If multiple options are grammatically correct, choose the one that is the most concise, clear, and unambiguous while retaining the original meaning. CAT SC often favors directness.
"Sound" Test: Read the chosen option aloud. Does it sound natural and fluent? This can often catch subtle awkwardness.
Beyond Rules: Practice and Review Strategies
Grammar Fundamentals First: Ensure you have a solid understanding of basic grammar. Rahul Sir Classes' study materials and workshops are excellent resources for this.
Error Log is Your Best Friend: Maintain an "Error Log." For every SC question you get wrong (or even right for the wrong reason), note down:
The question.
The correct answer.
Why you got it wrong (e.g., "Missed SVA," "Didn't recognize idiom").
The specific rule that applies.
How you'll avoid it next time.
Practice, Practice, Practice: The more questions you solve, the better you'll become at recognizing patterns and applying rules quickly.
Timed Practice: Once you're comfortable with accuracy, start timing yourself. Speed comes with confidence and repeated application of strategies.
Read Quality English: Cultivate a habit of reading well-written articles, editorials, and books. This subconsciously improves your "ear" for correct English.
