Chapter 3: Error Spotting Masterclass
Stop searching every word randomly. Learn how to scan a sentence, identify the most likely error zone, classify the error and reach the correct answer quickly in IBPS, SBI, SSC, RBI and other competitive examinations.
1. Welcome to the Exam-Solving Phase
You have already studied the major building blocks of English grammar. Now the objective changes.
From this chapter onward, the focus is not:
The focus is:
This is a completely different skill.
You do not need to consciously recall every grammar rule every time you solve a question. Your goal is to develop an error radar that tells you where to look first.
2. What Is Error Spotting?
In a typical Error Spotting question, a sentence is divided into multiple parts. One part contains a grammatical, structural, usage or contextual error.
The task is not merely to identify that something “sounds wrong.” You must identify why it is wrong.
The correct approach is:
3. The Four-Step Error Spotting Method
Suppose you notice that “are” looks suspicious. Do not immediately change it.
First ask:
- Is this a subject–verb agreement problem?
- Is the subject singular or plural?
- Is there an intervening phrase?
- Could the issue actually be tense or voice?
4. The IBPSHUB 10-Second Scan
In the examination, you cannot spend one minute analysing every sentence from the beginning.
Develop a rapid first scan.
5. The Error Radar
Certain words and structures repeatedly attract examiners. When you see them, slow down.
6. Error Classification — Your First Major Skill
Most Error Spotting questions can be classified into recurring categories.
| Error Type | What to Check | Typical Signal |
|---|---|---|
| Subject–Verb Agreement | Subject vs finite verb | is/are, has/have, was/were |
| Tense | Time and sequence | yesterday, since, already, by the time |
| Pronoun | Case, reference, agreement | he/him, who/whom, their/its |
| Preposition | Correct combination | depend on, interested in |
| Article | a/an/the/zero article | singular countable noun |
| Determiner | Quantity and noun type | much/many, fewer/less |
| Adjective/Adverb | Form and position | quick/quickly |
| Conjunction | Logical pairing | although/but, either/or |
| Parallelism | Equal grammatical structure | to read, writing, and speaking |
| Modifier | Logical attachment | opening participial phrase |
| Verb Form | Infinitive/gerund/participle | avoid to do / want doing |
| Usage / Idiom | Standard expression | common fixed combinations |
7. Error Priority — Where Should You Look First?
Not every part of a sentence deserves equal attention.
A useful priority order is:
This is not a rigid rule. It is a scanning priority. If something immediately looks suspicious elsewhere, investigate it. The purpose is to reduce wasted reading time.
8. The Most Important Question: “What Controls What?”
Advanced grammar is largely about relationships.
In Error Spotting, ask:
Which noun does the pronoun refer to?
Which word does the modifier describe?
Which words are being compared?
Which words are connected by the conjunction?
Once you understand these relationships, many difficult questions become much easier.
9. Trap #1 — The Nearest Noun
The nearest noun before the verb is “products”. But that does not make it the subject.
Strip away the prepositional phrase:
Therefore:
Never choose a verb merely because it agrees with the nearest noun. Find the grammatical subject first.
10. Trap #2 — “Along With” Is Not “And”
“His assistants” is additional information.
11. Trap #3 — Every Verb Form Is Not the Main Verb
“Preparing” looks like a verb, but it is functioning as a participle modifying “candidates”.
When you see multiple verb forms, identify which one carries tense and agrees with the subject.
12. Trap #4 — Prepositional Phrase Distraction
Ignore “of the examination”.
13. Trap #5 — Tense Without a Time Check
Do not judge a tense in isolation. First look for time indicators.
“Yesterday” refers to a completed, definite past time.
Whenever you see a tense-related verb, immediately search the sentence for time markers.
14. Trap #6 — Pronoun Reference
Who does “he” refer to?
The sentence can be grammatically formed but still be structurally ambiguous.
Pronoun questions may test not only grammatical case but also whether the pronoun has a clear antecedent.
15. Trap #7 — Comparison
Depending on intended meaning, the comparison may require a carefully constructed standard.
Comparative structures should always trigger a check:
16. Trap #8 — Conjunction Pairing
Standard formal English does not normally require both “although” and “but” to perform the same concessive connection.
OR
He was tired, but he continued working.
Correlative and paired conjunction structures should always be checked for proper pairing.
17. Trap #9 — Parallel Structure
The elements joined by “and” should follow a consistent grammatical pattern.
18. Trap #10 — Modifier Attachment
Who was walking down the road?
Grammatically, the opening participial phrase appears to modify “the tall buildings”, creating a logical problem.
19. The “Strip It Down” Technique
When a sentence is very long, temporarily remove:
- Prepositional phrases
- Relative clauses
- Participial phrases
- Parenthetical information
- Non-essential modifiers
Strip it down:
Correct:
20. The “Replacement Test”
If you are unsure whether a structure is functioning correctly, replace the suspicious element with a simpler form.
Simplify:
Therefore:
21. The “Question Test”
Asking a simple question can identify the grammatical role of a word.
| Question | What It Helps Identify |
|---|---|
| Who/what? | Subject |
| Does what? | Verb/predicate |
| Does what to whom/what? | Object |
| Describes whom/what? | Modifier/complement |
| Refers to whom/what? | Pronoun antecedent |
| Compared with whom/what? | Comparison structure |
22. Option Elimination Strategy
Some Error Spotting formats provide multiple possible corrections. In such cases, elimination can save valuable time.
Reject an option that creates a new grammatical error.
Reject an option that changes the intended meaning without grammatical justification.
Prefer the standard grammatical construction used in formal English.
Do not select an answer simply because it “sounds better.” Identify the rule.
23. What NOT to Do in Error Spotting
Long sentences contain deliberate distractions.
Some incorrect constructions may sound familiar because they are commonly used in everyday speech.
A suspicious word may actually be grammatically correct in context.
Grammar and meaning often work together.
Once a clear grammatical rule identifies the error, move on.
24. The 30-Second Deep Scan
If the 10-second scan does not reveal the answer, perform a deeper structural scan.
25. Practice Drill — Identify the Error Zone
Do not correct these sentences yet. Your first task is simply to identify what type of error you would investigate.
The list of selected candidates are displayed on the notice board.
Which area should you check first?
She has lived in Delhi since five years.
Which area should you check first?
Neither the manager nor the employees was willing to accept the proposal.
Which area should you investigate?
Having completed the assignment, the final report was submitted by the candidate.
Which area should you investigate?
The company aims at increasing production, reducing costs and to improve quality.
Which area should you investigate?
26. Practice Drill — Find the Error
The number of applicants have increased significantly this year.
The subject is “the number”, which is singular.
Correct: The number of applicants has increased significantly this year.
He is senior than me in the organisation.
The standard construction is: senior to.
Correct: He is senior to me in the organisation.
The manager as well as his assistants are responsible for the delay.
“As well as his assistants” does not make the subject plural.
Correct: The manager as well as his assistants is responsible for the delay.
The candidate who had prepared thoroughly were confident during the interview.
The subject of the main clause is “candidate”. The relative clause does not change the number of the main subject.
Correct: The candidate who had prepared thoroughly was confident during the interview.
Walking through the market, the shops appeared unusually crowded.
The opening participial phrase logically needs a subject that can perform the action of walking.
Better: Walking through the market, I found the shops unusually crowded.
27. Advanced Mixed Practice
Each of the students were given a separate assignment.
He is not only intelligent but also works hard.
Examine the parallel structure carefully.
The report, along with several supporting documents, were submitted yesterday.
She is one of the candidates who has successfully cleared the examination.
Examine the antecedent of the relative pronoun carefully.
The success of the programme depends not only on proper planning but effective execution also.
Check the correlative structure and parallelism.
28. The Error Spotting Decision Tree
↓
YES → Check agreement and tense
↓
Check pronouns
↓
Check verb + complement / preposition
↓
Check conjunctions and comparisons
↓
Check modifiers and parallelism
↓
Check usage / idiom / meaning
You do not have to perform every check on every question. Stop as soon as you have established a definite error.
29. The “Stop Rule”
Competitive exams reward both accuracy and time management.
Once you have:
- identified the error,
- confirmed the applicable rule, and
- verified that the remaining sentence is structurally acceptable,
STOP.
A common mistake among advanced students is continuing to search for a second error after finding a clear one. In a single-error question, this wastes time and can create unnecessary doubt.
30. How to Approach Different Exam Styles
| Exam | Approach |
|---|---|
| IBPS / SBI | Prioritise agreement, tense, prepositions, pronouns, modifiers, connectors and usage. |
| RBI | Expect greater emphasis on formal language, subtle grammar, usage and sentence logic. |
| SSC | Build strong command over grammar rules, error spotting patterns, sentence improvement and standard usage. |
| Other Banking Exams | Focus on high-frequency grammar traps and speed-based recognition. |
31. Your Error Notebook
Do not simply solve questions and move on.
Maintain an “Error Notebook” with four columns:
| Question | Error Type | Rule | My Mistake |
|---|---|---|---|
| The quality … are | SVA | True subject = quality | Followed nearest noun |
| senior than | Preposition | senior to | Used common comparison pattern |
Your personal error pattern is more valuable than a generic list of hundreds of rules. If you repeatedly make the same mistake, that becomes your highest-priority revision topic.
32. Speed Training
Error Spotting should eventually become almost automatic.

35. Chapter Revision — What You Must Remember
36. Final Challenge
Before looking for an answer, perform the full IBPSHUB scan.
FINITE VERB → ?
DISTRACTION → ?
ERROR TYPE → ?
CORRECTION → ?
Remove the distracting phrase:
The number of candidates → has increased.
“Along with several applicants who had registered late” does not create a compound subject.
Therefore:
The number of candidates appearing for the examination, along with several applicants who had registered late, has increased considerably compared with the previous year.
Error Type: Subject–Verb Agreement.
What Comes Next?
You now have the method.
The next chapters will give you the individual weapons needed to apply that method.
Chapter 16 will go deep into one of the most frequently tested Error Spotting areas: Subject–Verb Agreement.
It will focus almost entirely on exam traps, question patterns, shortcuts and high-frequency structures rather than basic theory.
