Error spotting tests your knowledge of grammar rules. The sentence looks correct at first glance, but one part violates a grammar rule. Your job is to catch that violation
The subject and verb must match in number and person. 2
All parts of the sentence should follow logical tense sequence. 3
Wrong prepositions are commonly tested. 4
Incorrect use of a, an, the. 5
Wrong pronoun forms or unclear antecedents. 6
Items in a series must follow the same grammatical structure.
Subject-verb disagreement (30%), Wrong prepositions (25%), Article mistakes (20%), Tense errors (15%), Others (10%)
Identify the main subject
Check if verb agrees with THIS subject (ignore words in between)
Common trap words: each, every, either, neither (always singular) Shortcut Formula 2 - The 'Preposition Memory' Rule: Different FROM (not different than) Consist OF (not consist in) Independent OF (not independent from)
Find the subject = 'Each' (singular)
Find the verb = 'have submitted' (plural)
Check agreement = 'Each' is always singular, so verb should be 'has submitted'
The error is in part (B) Answer: (B) Worked Example 2: Sentence: 'The committee discussed (A)/ about the new policy (B)/ in great detail (C)/ yesterday (D)/ No error (E)' Step-by-step Solution:
Check each part for grammar violations
Part A: 'discussed' - correct tense
Part B: 'discussed about' - Wrong! 'Discuss' never takes 'about'
Should be 'discussed the new policy' Answer: (B) Shortcut Formula 3 - The 'Either-Neither' Rule: Either/Neither + singular verb Either...or/Neither...nor + verb agrees with the subject closer to the verb The #1 Most Common Trap: Students focus on the wrong subject! In complex sentences, there are multiple nouns. Always identify the MAIN subject that the verb should agree with. Ignore prepositional phrases and relative clauses when checking subject-verb agreement. For example: 'The box of chocolates ARE delicious' - Students see 'chocolates' and think plural verb is correct. But the main subject is 'box' (singular), so it should be 'IS delicious'. Time Management Tip: Spend maximum 20 seconds per question. If you can't spot the error quickly, mark 'No error' and move on. Don't waste time overthinking. Common Error Categories to Memorize: - Countable vs Uncountable nouns (much/many confusion) - Comparative degree errors (more better is wrong) - Redundancy (ATM machine, PIN number) - Idiom violations (take interest IN, not take interest ON)
