Common error types
- Subject-verb agreement, tense, articles, prepositions, word form.
- Spelling and punctuation (commas, apostrophes, capitals).
Strategy
- Read each line carefully; one error per line in SPM editing.
- Check small words (a/an/the, is/are, in/on).
Key idea
SPM editing tasks hide one error per line; check agreement, tense, articles, prepositions, spelling and punctuation.
Remember
Small words — articles and prepositions — are the most common hidden errors.
