The same fault families recur as error-spotting (agreement, tense, comparison, prepositions, inversion), so the elimination ladder — verb form, agreement, structure, word choice, economy — resolves most items in under thirty seconds.

Question patterns exams keep repeating
Taken from previous-year papers. If a pattern is marked "very common", expect to see it in your exam.
Tense fix
very commonThe bold part is a verb and the sentence has a time clue like 'already', 'yesterday', 'by the time'.
Circle the time clue and pick the tense it needs.
The earlier of two past events takes 'had + V3'.
Improve the part 'already left': When I reached the station, the train already left. Options: had already left / has already left / No improvement / already leaves
Two past events: reaching and leaving
The train left first
The earlier event takes the past perfect
Answer: had already left
Agreement fix
very commonThe bold part has was/were or has/have after a phrase like 'of ...' or 'as well as'.
Cover the extra phrase and find the real subject.
Match the helping verb to it.
Improve the part 'were': The captain, as well as the openers, were blamed for the collapse. Options: was / No improvement / have been / are
Cover 'as well as the openers'
The subject is 'the captain' (singular)
The sentence is past, so 'was'
Answer: was
Reported speech fix
commonA past reporting verb like 'asked' or 'told' is followed by a part in question order or the wrong tense.
In a reported question use statement order.
Move the tense one step back and keep only one joining word.
Improve the part 'why was he': The teacher asked the boy why was he late again. Options: why he was / No improvement / why is he / that why he was
A reported question takes statement order
Subject first: 'he was'
'that why' has two joining words
Answer: why he was
Comparison fix
commonThe bold part has 'more better', or compares things that do not match, like 'streets than a city'.
Remove double markers.
Compare like with like: use 'those of' for plural things.
Improve the part 'Bangalore': The streets of Mysuru are cleaner than Bangalore. Options: those of Bangalore / that of Bangalore / No improvement / Bangalore's streets
We must compare streets with streets
'streets' is plural
So use 'those of'
Answer: those of Bangalore
Preposition and repeated word fix
very commonThe bold part has a small word after a verb, or a repeated idea like 'revert back'.
Learn each verb with its partner word: approve of, insist on, comply with.
If an idea repeats, cut the extra word.
Improve the part 'revert back': Please revert back to my mail by Friday. Options: revert to / No improvement / revert back to / reversing to
'revert' already means 'come back'
'back' repeats the idea
Remove it
Answer: revert to
Article fix
commonThe bold part is an article + noun, like 'a ancient' or 'an useful'.
Say the next word aloud.
Vowel sound: an. Consonant sound: a.
Improve the part 'a ancient': The temple was built near a ancient trading route. Options: No improvement / an ancient / a ancients / the ancients
'ancient' begins with a vowel sound
A vowel sound needs 'an'
The rest of the sentence is fine
Answer: an ancient
Inversion fix
commonThe sentence starts with 'No sooner', 'Hardly' or 'Never' and the bold part keeps normal word order.
After these openers put the helping verb before the subject.
No sooner goes with 'than'.
Improve the part 'the train had left': No sooner the train had left the platform than the TTE began checking tickets. Options: had the train left / No improvement / the train left / the train had leave
'No sooner' at the start needs the helping verb first
So 'had' comes before 'the train'
The rest of the sentence stays the same
Answer: had the train left
Misplaced opening phrase
occasionalThe sentence opens with an -ing or 'being' phrase whose doer does not fit, like 'Being a rainy day, ...'.
Ask who does the opening action.
That doer must be the main subject, or the opening phrase needs its own subject.
Improve the part 'Being a rainy day': Being a rainy day, the mela was cancelled by the committee. Options: It being a rainy day / No improvement / Being rainy day / Been a rainy day
The mela cannot be 'a rainy day'
Give the opening phrase its own subject 'it'
This gives 'It being a rainy day'
Answer: It being a rainy day
When no change is needed
commonThe bold part already follows every grammar rule, while each option adds a mistake.
Check the bold part for tense, agreement and word choice.
If all are right, choose 'No improvement'.
Improve the part 'has been teaching': She has been teaching in this school since 2015. Options: teaches / is teaching / No improvement / has taught
'since 2015' links the past to now
She is still teaching
So the present perfect continuous is correct
Answer: No improvement
