Frequently Asked Questions on Error Spotting
How many error spotting questions are asked in SSC CGL Tier 1 and Tier 2?
In SSC CGL Tier 1, Error Spotting accounts for 2 to 3 questions (4 to 6 marks). In Tier 2, Error Spotting and Sentence Improvement together contribute 8 to 12 questions (24 to 36 marks).
Which grammar chapters are most repeated in SSC CGL Error Spotting?
Historic exam data reveals that over 75% of spotting errors stem from five key topics: 1) Subject-Verb Agreement, 2) Fixed Prepositions, 3) Conditional Sentences, 4) Pronoun Reference & Cases, and 5) Parallelism & Modifiers.
What is the best step-by-step strategy to spot errors quickly?
Use the 4-step diagnostic scan: 1) Identify the main subject and verify verb agreement; 2) Check tense consistency across clauses; 3) Verify prepositions following verbs/adjectives; 4) Check modifier placement and parallel grammatical structures.
What is the conditional sentence error trap in SSC CGL?
Never use 'would have' in the 'if' condition clause. The third conditional formula is strictly: 'If + Subject + had + V3, Subject + would have + V3'. Using 'If he would have known' is grammatically incorrect.

Tier 2 imposes a heavy 1.00 mark penalty per incorrect response. If you cannot identify a definite grammatical violation after checking Subject-Verb Agreement and Prepositions, consider 'No Error' rather than guessing.
