The 4-Step Elimination Strategy
Read the full sentence first
Understand the meaning before looking at options. If you spot an obvious error while reading, mark it mentally.
Identify the grammar zone
Is it a verb issue (tense/mood/agreement), a pronoun issue, a comparison issue, or a preposition issue? This narrows the rule set.
Eliminate using rules
Cross out options that create new errors. Often 2 options are immediately wrong, leaving you to choose between 2.
Check 'No improvement' last
About 20–25% of questions have 'No improvement' as the answer. Only choose it after ruling out all real improvements.
Top 10 Error Patterns
Ranked by frequency in SSC CGL, CHSL, IBPS PO, and UPSC papers.
Wrong
She is more better than her sister.
Right
She is better than her sister.
Remember
Never use 'more' + '-er' or 'most' + '-est' together. Choose one method of comparison.
Wrong
He is senior than me.
Right
He is senior to me.
Remember
senior, junior, superior, inferior, prior, anterior, posterior → always use 'to'.
Wrong
The committee have taken their decision.
Right
The committee has taken its decision.
Remember
When acting as one body (unanimous decision, single vote), use singular verb + singular pronoun.
Wrong
No sooner the bell rang when students ran out.
Right
No sooner did the bell ring than students ran out.
Remember
No sooner + inversion (did/had) + subject + bare V ... than + clause.
Wrong
I am used to get up early.
Right
I am used to getting up early.
Remember
'Be used to' = accustomed to → gerund. 'Used to' = past habit → base verb.
Wrong
Hardly had she entered the room than she fainted.
Right
Hardly had she entered the room when she fainted.
Remember
'Hardly/Scarcely/Barely' → 'when'. 'No Sooner' → 'than'. Do not swap.
Wrong
Between you and I, this will fail.
Right
Between you and me, this will fail.
Remember
Prepositions (between, for, with, by) must be followed by object pronouns: me, him, her, us, them.
Wrong
If I was you, I would not accept it.
Right
If I were you, I would not accept it.
Remember
Unreal / hypothetical conditions use 'were' for all persons, never 'was'.
Wrong
She avoided to meet him.
Right
She avoided meeting him.
Remember
avoid, mind, enjoy, consider, suggest, deny, postpone, risk, practise → V+ing only, never to-infinitive.
Wrong
One of the best player that has represented...
Right
One of the best players that have represented...
Remember
After 'one of the best', use plural noun. The relative clause refers to that plural noun → plural verb.
Quick Reference
| Pattern | Rule |
|---|---|
| Double comparative | Use only -er or more, not both |
| Latin comparative | Use 'to', not 'than' |
| No Sooner | Inversion + than |
| Hardly / Scarcely | Inversion + when |
| Used to vs Be used to | Past habit vs accustomed |
| Subjunctive were | All persons use 'were' |
| Gerund-only verbs | V+ing, never to-V |
| Collective noun | Singular when acting as unit |
| One of the best | Plural noun + plural verb in clause |
| Preposition + pronoun | Use object pronoun |
3 Examiner Traps to Avoid
Trap 1: 'No improvement' temptation
Examiners write sentences with subtle errors. Don't rush to 'No improvement'. Read every word carefully.
Trap 2: Partial fixes in options
An option may fix one error but introduce another (e.g., correct the verb but wrong the pronoun). Check the whole option.
Trap 3: Meaning shifts
'Used to get up' (past habit) ≠ 'am used to getting up' (current habit). Both are grammatical but mean different things.
