Error Spotting for Bank and SSC Exams: The Scan Method

Introduction

Error spotting gives you a sentence split into four or five parts. One part contains a grammatical error, and you name that part. If no part is faulty, you choose no error.

Here is the point that changes how you should work, and most guides never state it. You only have to find the fault. You never have to fix it.

That sounds obvious and it has a real consequence. In sentence improvement you must know the correct version, so you need the full rule. In error spotting you only need to know that a rule has been broken. Seeing that each of the students have is wrong is enough to mark part B, and you can move on without deciding between has and has been.

The second point follows from the first. The worst method is reading the whole sentence and waiting for something to feel wrong, because exam sentences are written to sound acceptable. The best method is scanning in a fixed order, checking the places where errors actually hide.

Where This Topic Is Asked

Add those together and this is one of the largest grammar blocks in any English paper. It is also the most predictable, because the same twenty or so rules are tested year after year. Confirm the pattern for your own paper in the exam-wise syllabus hub and the latest notifications.

Two Facts About the Format

• No error is a real answer. It is correct in roughly 15 to 20 per cent of questions, and students under-choose it because they assume a fault must exist.
• The verb is the culprit far more often than anything else. Analysis of previous papers puts it at around 60 per cent of questions, counting agreement, tense and voice together.

Those two facts alone should reshape your approach. Check the verb first, every time, and be willing to mark no error when the scan comes up clean.

The Scan Method

Do not read for meaning and hope a fault jumps out. Work through the sentence in this fixed order.

If the scan finishes clean, mark no error and move on. A clean scan is evidence, not a failure to find something. Students who distrust the scan go round again, and a second pass is where invented errors come from.

Where Errors Usually Sit

Errors are not evenly spread across the parts. Knowing the usual positions saves several seconds a question.

The Strike-Out Technique

Most agreement errors are built the same way: a phrase is inserted between the subject and the verb so that a noun of the wrong number sits next to the verb. The cure is mechanical.

Strike out everything between commas, everything after as well as, along with, together with or besides, and everything inside a relative clause. What remains is the real subject. Test the verb against that.

• The list of selected candidates have been published. Strike out of selected candidates. What remains is the list, so the verb must be has.
• The captain, along with the players, were felicitated. Strike out the phrase between commas. What remains is the captain, so the verb must be was.
• A number of colourful glass vases was displayed. Here the subject phrase means several, so the verb must be were. Note that the number of works the opposite way and takes a singular verb.

Trigger Words: The Fastest Route to the Error

Some words cannot appear alone. Each one demands a fixed partner or a fixed structure, so the moment you see it you know exactly what to test. Learning this table is the single highest-return hour you can spend on this topic.

Twenty triggers, and each one gives away the answer the moment you see it. So a sentence beginning with No sooner or Hardly should send you straight to two checks: is the auxiliary inverted, and is the partner word correct.

The Rule Catalogue

Nouns

• Singular in form, plural in sense. Police, cattle, peasantry, gentry, people, clergy and vermin take plural verbs. The cattle were grazing, not was grazing.
• Always plural in form. Scissors, trousers, spectacles, premises, thanks and tidings take plural verbs.
• Nouns of measure stay singular before another noun. A nine-metre cloth, a five-year plan, a ten-rupee note.
• Uncountable nouns take singular verbs and no plural form. Information, furniture, luggage, advice, news, equipment and machinery. Much information, never many informations.
• Collective nouns take a singular verb as one unit and a plural verb when the members disagree. The jury was unanimous against the jury were divided in their opinions.
• Two roles held by one person take a singular verb. The secretary and treasurer is Mr Sharma, when one person holds both posts.

Pronouns

• One must be maintained. One must do one's duty, never one must do his duty.
• After like, unlike and let, use the object form. A woman like her, let me do it, let him and me go.
• After a preposition, use the object form. Between you and me, never between you and I.
• Everyone, everybody, each and nobody are singular, so the pronoun is his or her by the rule Indian exams follow, though modern usage increasingly accepts the plural form.
• A collective noun with a singular verb takes a singular pronoun. The team has completed its project.
• Who is for people and which for things, including institutions such as a ministry or a committee.

Verbs

• Purpose takes an infinitive. He went to the mall to watch a film, not for watching a film.
• An irritating repeated action takes the present continuous. He is always hitting me conveys the annoyance that he always hits me does not.
• Two future actions. The conditional clause takes the simple present and the main clause takes the future. As soon as he enters the room, we will start.
• Impossible past conditions. Use the past perfect in the if clause and would have plus the third form in the result. If Joan had invited me, I would have gone. Never if Joan would have invited me.
• Two past actions. The earlier one takes the past perfect. By the time we reached, he had left.
• Some verbs take only an infinitive — want, wish, expect, hope, decide, agree, refuse. Others take only a gerund — enjoy, avoid, finish, mind, suggest, consider. I enjoy reading, never I enjoy to read.
• After a preposition, always a gerund. Fond of reading, interested in learning.
• Wish takes the past subjunctive, not the future. Ram wishes he were richer, never Ram wishes he will be richer.

Adjectives and Adverbs

• Fewer counts, less measures. Fewer than twenty people, less water.
• An adverb modifies a verb. He runs quickly, he performed well, never he performed good.
• Never double a comparative or superlative. Better, never more better. Tallest, never most tallest.
• Use a comparative for two and a superlative for more than two. The better of the two, the best of the three.

Articles, Prepositions and Structure

• Superlatives take the, while abstract nouns generally take no article. The best student, but honesty is the best policy.
• A or an is decided by sound, not spelling. A university, an hour, an heir.
• No preposition before upstairs, downstairs, inside, outside, uptown or downtown. He went upstairs, never went to upstairs.
• Fixed pairs. Good at, interested in, depend on, different from, consist of, comprise nothing, married nothing, die of a disease and die from an injury.
• Parallelism. Items in a list share a form. Reading, writing and swimming, never reading, writing and to swim.
• Modifiers sit beside what they modify. Walking down the street, I saw beautiful trees, because the trees were not walking.
• No double negatives. I did not do anything or I did nothing, never I did not do nothing.
• No redundancy. Return back, repeat again, more superior, past history and free gift all say the same thing twice.

The No-Error Decision

Run the five-step scan once. If the verb agrees and matches the time marker, no trigger word is unpaired, the articles and prepositions are standard, and the structure is parallel with modifiers in place, then choose no error and move on.

Two warnings apply in opposite directions. Students who never choose it lose the one question in six where it is correct. Students who choose it whenever they are unsure lose the questions where a rule really was broken. The scan, not your confidence, should decide.

Ten Solved Questions

1. Ram wishes (a) / he will be (b) / richer. (c) / No error (d)

Working: Wish expresses an unreal situation and takes the past subjunctive, not the future. The correct form is he were richer. Answer: (b).

2. The associate gave us (a) / much informations (b) / which we needed. (c) / No error (d)

Working: Information is uncountable and has no plural form. Answer: (b). Note that much is correct, which is what makes the error easy to miss.

3. No sooner did I leave home (a) / when it started raining heavily (b) / which drenched me completely. (c) / No error (d)

Working: A trigger word opens the sentence. No sooner pairs with than, while hardly and scarcely pair with when. Answer: (b).

4. She was (a) / quite amusing (b) / at that story. (c) / No error (d)

Working: A person who finds a story funny is amused, not amusing, and the preposition is by or at depending on the sense. The participle is the fault. Answer: (b).

5. After a complaint was filed (a) / police teams was given the photograph (b) / of the accused (c) / recorded at the hotel. (d) / No error (e)

Working: Teams is plural and takes were. Answer: (b). The verb was the first thing to check and it settled the question in a few seconds.

6. Shahjahan was (a) / an heir at (b) / the Mughal throne. (c) / No error (d)

Working: One is an heir to a throne, not at it. The article an before heir is correct, since the h is silent and the word begins with a vowel sound. Answer: (b).

7. The government is still in the (a) / process of finalized new policy (b) / guidelines for the allocation of land. (c) / No error (d)

Working: The preposition of must be followed by a gerund, so it should read process of finalising. Answer: (b).

8. The fight for liberation (a) / brings out the best and (b) / a noblest quality in mankind. (c) / No error (d)

Working: A superlative takes the, never a. It should read the noblest quality. Answer: (c).

9. Each of the students (a) / have submitted (b) / their assignments (c) / on time. (d) / No error (e)

Working: Each is singular whatever noun follows it, so the verb must be has. Part (c) also invites suspicion, but a question has one intended answer and the verb error is the clearer one. Answer: (b).

10. The committee (a) / has decided (b) / to postpone (c) / the annual meeting. (d) / No error (e)

Working: The collective noun is acting as one unit and takes a singular verb, which it has. The infinitive is correct and the article is correct. The scan comes up clean. Answer: (e).

Worked Examples: Wrong to Right

Example 1 (reading by feel)

Sentence: A student reads the whole sentence twice, waiting for something to sound wrong, and finds nothing.

Trap: Exam sentences are written to sound acceptable, so the ear is the tool the examiner is defeating. A fixed scan checks the places where errors actually hide, rather than waiting for one to announce itself.

Correct Answer: Scan in order: verb, trigger words, small words, structure.

Rule in Simple Words: Hunt in the likely places rather than listening for a wrong note.

Example 2 (agreement with the nearest noun)

Sentence: A student accepts the list of selected candidates have been published.

Trap: Candidates is plural and sits directly beside the verb, so the plural form sounds natural. The subject is list, and everything between the subject and the verb is decoration.

Correct Answer: Has been published.

Rule in Simple Words: Strike out the middle phrase before testing the verb.

Example 3 (missing a trigger word)

Sentence: A student reads No sooner had we started when the power failed and finds it acceptable.

Trap: When feels natural after a time expression, and the inversion looks correct. No sooner has exactly one partner, which is than.

Correct Answer: No sooner had we started than the power failed.

Rule in Simple Words: Certain words announce their own error, so learn their partners.

Example 4 (skipping a short part)

Sentence: For an heir at the Mughal throne, a student passes over the two-word segment and checks the longer parts instead.

Trap: Short parts look too small to hold a mistake, and the eye skips them. Prepositions and articles are exactly where examiners hide errors, precisely because they are skipped.

Correct Answer: An heir to the Mughal throne.

Rule in Simple Words: A three-word part deserves the same attention as a ten-word part.

Example 5 (uncountable nouns)

Sentence: A student accepts much informations because much is correctly used.

Trap: Half the phrase is right, which makes the whole phrase feel right. Information has no plural form at all, along with furniture, luggage, advice and news.

Correct Answer: Much information.

Rule in Simple Words: Learn the uncountable list, because these words never take an s.

Example 6 (going round a second time)

Sentence: A student completes a clean scan, distrusts it, reads again and marks a part that was actually correct.

Trap: Choosing no error feels like giving up, so a second pass feels responsible. On a second pass every part starts to look suspicious, and that is where invented errors come from.

Correct Answer: Trust the scan and mark no error.

Rule in Simple Words: One scan, one decision.

Example 7 (would in the if clause)

Sentence: A student accepts if Joan would have invited me, I would have gone.

Trap: Both halves use would have, so the sentence looks internally consistent. The if clause of a past conditional takes the past perfect, and would belongs only in the result clause.

Correct Answer: If Joan had invited me, I would have gone.

Rule in Simple Words: No would after if.

Example 8 (spending too long)

Sentence: A student cannot settle between two parts and works on the question for two minutes.

Trap: The answer always feels one reading away, and abandoning a question feels wasteful. Two minutes on one mark costs three other questions in a timed section.

Correct Answer: Give the question forty-five seconds, decide between the two survivors, and move on.

Rule in Simple Words: Scan once, choose, and go.

Common Traps Students Fall Into

These are the habits that most often cost marks. Each one is a common trap, not a silly mistake, and each has a one-line fix.

• Trap: Reading by feel. Fix: Scan in a fixed order, since sentences are written to sound acceptable.
• Trap: Not checking the verb first. Fix: The verb carries the error in roughly three questions out of five.
• Trap: Matching the verb to the nearest noun. Fix: Strike out the middle phrase and test against what remains.
• Trap: Skipping short segments. Fix: Prepositions and articles hide in exactly those parts.
• Trap: Ignoring trigger words. Fix: No sooner, hardly, lest, though, unless, one of and between each demand a fixed partner.
• Trap: Never choosing no error. Fix: It is correct in roughly one question in six.
• Trap: Choosing no error whenever unsure. Fix: Let the completed scan decide, not your confidence.
• Trap: Making a second full pass. Fix: One scan, one decision, because a second pass invents faults.
• Trap: Trying to work out the correction. Fix: You only have to find the error, never repair it.
• Trap: Hunting for exotic rules. Fix: Most errors are agreement, tense, preposition or article, so check the common ones first, as covered in subject-verb agreement.
• Trap: Practising without recording the rule. Fix: After each wrong answer, write the rule you missed, exactly as in sentence improvement practice.

Memory Tricks and Formulas

1. Find, do not fix

You are asked which part is wrong, not what the right version is. Seeing that a rule is broken is enough, and working out the correction is time you did not need to spend.

2. Verb first, always

Agreement, tense and voice together account for around 60 per cent of errors. So find the verb before you look at anything else, and ask three questions: does it agree, is the tense right, is the voice right.

3. Strike out the middle

Cover everything between commas, everything after along with or as well as, and everything inside a relative clause. What remains is the real subject. This single move solves most agreement questions.

4. Trigger words give themselves away

No sooner takes than. Hardly and scarcely take when. Though takes yet. Unless and lest never take not. Neither takes nor. Between takes and. Learn twenty of these and a whole class of questions becomes instant.

5. Small parts, big errors

A segment of three or four words is usually there for a reason. Articles and prepositions are the easiest things to read past, which is exactly why examiners put the fault there.

6. One scan, one decision

Complete the five steps once and commit. A second full pass makes correct parts look doubtful, and most invented errors are found on the second reading rather than the first.

7. Skip the disputed rules

Some rules are contested even among grammarians, such as taller than I against taller than me, or whether an infinitive may be split. Never choose such a part as the error unless every other part is clean.

8. The 45-second clock

Allow 30 to 45 seconds a question: ten seconds to read, twenty-five to scan, ten to decide. With 3 to 7 questions in a paper, the block should take about four minutes.

Frequently Confused Pairs

Repeating Question Patterns

• The proximity trap, where a plural noun is placed beside a singular subject to attract the wrong verb.
• Trigger-word mismatches, especially no sooner with when and though with but.
• Uncountable nouns given a plural form, such as informations, furnitures and advices.
• A preposition or article hidden in a very short segment.
• Conditional mixing, with would appearing in the if clause.
• No-error questions, which students under-choose because they assume a fault must exist.

Three of those fifteen had no error, which is close to the real proportion. Notice too how many were settled by a trigger word: items 3, 6, 11, 12 and 13, a third of the set. Practise the same scan with the free English MCQ quizzes and full papers from the mock test archive.

Quick Revision

Error spotting is the most systematic topic in the English paper, because the same twenty rules return every year and each one can be checked mechanically. So scan rather than listen, take the verb first, learn the trigger words until they announce themselves, and trust the scan when it comes up clean. Build the rules underneath through subject-verb agreement and tenses, then convert detection into correction through sentence improvement and phrase replacement. Reading editorials keeps the ear tuned to correct usage, so ten minutes of daily current affairs reading helps here too. The wider set is in the topic-wise English notes.
