Grammar and correct usage for the NAPOLCOM exam: the short rule set the items keep returning to.
Grammar items on the NAPOLCOM exam do not test the whole of English grammar. They test a short list of rules, the ones that produce errors in real writing, and they test the same rules every sitting. This page sets out that list, the shape each item takes, and the one habit that makes the difference: naming the rule in play before reading the options.

The three item shapes
Error spotting gives a sentence with lettered parts and asks which part contains the error, or whether there is none. Sentence completion gives a sentence with a blank and asks which option fits grammatically. Correct-sentence items give four versions of a sentence and ask which one is right. All three are the same test in different clothes: do you know the rule, and can you see where it applies.
The rules that carry the marks
Five rules account for most items. Subject-verb agreement, especially when a phrase sits between the subject and the verb ('each of the applicants was') or when the subject is indefinite ('everyone has'). Tense consistency and sequence ('had left before the patrol arrived'). Pronoun reference and case ('between you and me'; 'the officer and I'). Parallel structure in lists ('to patrol, to report and to testify'). And the confused pairs: affect and effect, its and it's, fewer and less, who and whom, lie and lay.
| Rule | The usual trap | The check |
|---|---|---|
| Subject-verb agreement | A plural noun in a phrase between a singular subject and its verb | Find the subject; ignore everything between it and the verb |
| Tense | A time word the verb does not match | Find the time word (yesterday, since, by the time) and set the tense to it |
| Pronoun case | 'I' after a preposition or 'me' as a subject | Drop the other person: 'between you and me' because 'between me' |
| Parallel structure | One item in a list in a different form | Make every item the same shape |
| Confused pairs | The wrong twin in a familiar pair | Know the pair cold; there is no reasoning shortcut |
Name the rule first
Reading the options first invites the ear to pick what sounds familiar, and the exam's wrong options are written to sound familiar. Instead, read the sentence, find the verb, find its subject, find the time words and the pronouns, and name which rule the item is testing. Then the options are a yes-or-no check rather than a choice among four plausible sentences. On error-spotting items, the same habit tells you where to look; on 'no error' options, it tells you when to trust that nothing is wrong.
Worked examples
These items are written specifically for this guide. The actual practice bank pulls from a separate pool of original NAPOLCOM-style items reviewed by passers.
Item 01
Identify the error: Each of the recruits (A) were told (B) to report (C) at seven. No error (D).
- AEach of the recruits
- Bwere toldCorrect
- Cto report
- DNo error
Explanation. The subject is 'each', which is singular; 'recruits' is inside a prepositional phrase and does not govern the verb. 'Was told' is correct. This is the single most common agreement trap on the exam.Item 02
Choose the correct sentence.
- AThe complaint was filed by the neighbour and I.
- BThe complaint was filed by the neighbour and me.Correct
- CThe complaint was filed by me and the neighbour.
- DThe complaint was filed by myself and the neighbour.
Explanation. After the preposition 'by' the pronoun is objective: 'me'. Drop the neighbour and the test is obvious ('filed by me'). C is grammatical but puts the speaker first, which is the courtesy error the exam counts against; D misuses the reflexive.Item 03
Complete the sentence: By the time the patrol arrived, the suspect blank.
- Ahas fled
- Bfled
- Chad fledCorrect
- Dis fleeing
Explanation. 'By the time' plus a past event puts the earlier action in the past perfect: 'had fled'. The time phrase decides the tense, which is why finding it first is the method.

Study tactics that actually move the score
- 01
Find the subject before the verb, and ignore every phrase between them. Most agreement errors live in that gap.
- 02
Circle the time words. 'Since', 'by the time', 'yesterday' and 'already' each fix a tense.
- 03
For pronoun case, drop the other person from the sentence and read what is left.
- 04
Learn the confused pairs as a list and test yourself on them weekly; there is no rule to reason from, only recall.
Frequently asked questions
Does the NAPOLCOM exam have 'no error' options?
Error-spotting items commonly include a 'no error' option. Treat it as a real answer: if you have named the rule on every part and nothing breaks it, choose it.
How much grammar do I need to review?
The five rules on this page, drilled until automatic, cover most items. Depth on those beats breadth across grammar you will not be asked.
Is it American or British usage?
Philippine English follows American conventions in spelling and most usage. The exam does not test spelling variants.
