The 15 Most Tested Grammar Rules in IBPS PO
1Subject-Verb Agreement (25% of All Errors)
This is the highest frequency error type. The verb must agree with the subject in number and person.
Common error patterns:
- Singular subjects with plural verbs: "The committee have decided" ❌ → "The committee has decided" ✓
- Prepositional phrase confusion: "One of the students were absent" ❌ → "One of the students was absent" ✓
- Collective nouns: "The team are playing" (mostly ❌ in formal writing) → "The team is playing" ✓
IBPS PO trick: When "along with," "as well as," "together with" appear, the verb agrees with the first subject, not the phrase. "The manager, along with his team, is attending" ✓
2Tense Consistency & Usage (20% of Errors)
Incorrect tense switching within sentences or using wrong tense for time context.
Common errors:
- Past perfect misuse: "When I reached, the train left" ❌ → "When I reached, the train had left" ✓

High-frequency patterns:
- Interested in (not "interested about")
- Different from (not "different than" in formal writing)
- Comply with (not "comply to")
- Prefer X to Y (not "prefer X than Y")

Common patterns:

- No article before plural generalization: "The banks play important role" ❌ → "Banks play an important role" ✓
- A vs An: Based on sound, not spelling: "an MBA" ✓, "a European country" ✓
5Pronoun Errors (12% of Errors)
Wrong pronoun case, ambiguous reference, or pronoun-antecedent disagreement.
Common error patterns:
- Subject vs object pronouns: "Between you and I" ❌ → "Between you and me" ✓
- Pronoun-antecedent agreement: "Each student must bring their book" ❌ → "Each student must bring his/her book" ✓
- Ambiguous reference: "Ravi told Rahul that he was selected" (unclear who) ❌
IBPS PO specific: Formal writing prefers "one" over "you" for general statements, though both are acceptable.
6Modifier Placement (8% of Errors)
Misplaced or dangling modifiers create confusion about what is being modified.
Common errors:
- Dangling modifier: "Walking to the bank, the documents were forgotten" ❌ → "Walking to the bank, I forgot the documents" ✓

Trap 2: Colloquial vs Formal English
What sounds correct in spoken English may be wrong in formal writing.
"Who did you give it to?" ✓ (acceptable)
