Error spotting and sentence correction: scan by category, not by ear

Error spotting and sentence correction reward a method that most candidates skip: scanning the sentence against a fixed list of rules rather than reading it for what sounds wrong. Setters deliberately write errors that sound fine in speech, so the ear is the wrong instrument. The checklist is the right one.

The rule checklist

Run every sentence past these, in roughly this order:

• Subject-verb agreement. Match the verb to the true subject, not to a noun that happens to sit next to it. “The list of items is long”, not are.
• Tense consistency. Tenses must agree across clauses; a reported or conditional sentence fixes which tense is allowed.
• Prepositions. Many verbs and adjectives take a specific preposition — comply with, capable of, superior to. These are pure recall.
• Articles. A, an and the by rule, including the zero article before uncountable and general plurals.
• Pronoun agreement. A pronoun must match its noun in number and be unambiguous.
• Parallelism. Items in a list must share the same grammatical form.
• Modifiers. A describing phrase must sit next to what it describes.
• Degrees of comparison. Comparative for two, superlative for more; watch double comparatives and wrong “than/as” pairings.

Most questions live in the first four rows, so drill those hardest.

How to scan under time pressure

Read the sentence once, and as you do, test each rule that applies. The moment a rule breaks, that segment is your answer — you do not need to find a second fault. If nothing breaks after a full pass, the answer is no error or no correction required, which is a real and frequently correct option, not a cop-out.

A worked reading

“One of the students have not submitted their assignment.” Scan: the subject is one, not students, so the verb must be has. The plural students sits beside the verb to tempt the agreement error. Found on the subject-verb pass, in one read.

Where the marks leak

Trusting your ear. The errors are built to sound acceptable; use the checklist.

Matching the verb to the nearest noun. Find the real subject, which is often separated from the verb by a phrase.

Never choosing “no error”. It is a genuine option; a grammatically correct sentence has no error to spot.

Fixing more than one thing. In improvement questions, change only what a rule requires, and keep the rest of the sentence intact.

Practice that transfers

Grammar improves by repeated exposure to the same rule set, so drill in short, frequent bursts. Work through the error spotting and sentence improvement practice set, and reinforce the vocabulary side with fill in the blanks and vocabulary.
