10.1 Grammar Item Format
Key Takeaways
Historical overview materials illustrate Grammar with Correct/Incorrect judgments; current sources confirm the skill but not that exact shell
Grammar is one of five published writing skills; MCOLES does not publish its current item count or weight
Classic traps include subjunctive were vs. was and subject-verb disagreement across intervening phrases (remarks … was)
Use a fixed scan: subject/verb, tense/form, pronouns, punctuation, sentence sense
Site quizzes use four options to train the same standard-English rules without assuming a current test-day option shell
10.1 Grammar Item Format
Quick Answer: Grammar is a published skill. Historical overview materials illustrate it with a Correct/Incorrect sentence judgment, but current sources do not guarantee that exact shell. Grammar is one of the five writing-skill categories named in the current MCOLES contract; its current item count and weight are not published.
Use a Fixed Grammar Scan
A sentence can sound formal and still contain an error. Check it in a consistent order:
- Subject and verb: Find the simple subject and make the verb agree in number.
- Verb form and tense: Check auxiliaries, participles, and timeline consistency.
- Pronouns: Check case, number agreement, and clear antecedents.
- Sentence structure: Reject fragments, comma splices, and run-ons.
- Punctuation: Check commas, apostrophes, and end punctuation.
- Meaning: Make sure modifiers attach to the intended word and list items remain parallel.
In sentence-judgment practice, if one rule clearly fails, the sentence is incorrect. If all checks pass, do not change the answer merely because the wording feels unfamiliar.
High-Yield Error Patterns
Intervening phrase: “The list of stolen items were recovered” is incorrect because the singular subject list requires was. The plural noun inside the prepositional phrase does not control the verb.
Compound subject: Subjects joined by and are usually plural. With either/or and neither/nor, agreement usually follows the nearer subject.
Pronoun case: Remove the other name from a compound to test the form: “Dispatch asked Officer Chen and me,” not “Officer Chen and I.”
Incomplete sentence: A dependent clause beginning with because, although, or when cannot stand alone unless the rest of the sentence completes the thought.
Modifier placement: Put a descriptive phrase beside the word it modifies so the reader cannot attach it to the wrong person or action.
Practice-Site Format vs Test Skill
OpenExamPrep questions use four choices to teach why a sentence passes or fails. The underlying MCOLES skill is standard written-English grammar; do not infer the current live item shell from our practice format. Focus on naming the controlling rule, not memorizing a particular practice stem.
Study Without a Claimed Percentage
Some older prep material labels Grammar as about 14% of the full test. The current primary sources do not publish that weight. Grammar remains worth systematic practice because the rules are learnable and transfer across many items, but study time should follow your diagnostic errors rather than an unsupported percentage.
Which practice task most directly develops the published MCOLES Grammar skill?
Decide whether a presented sentence is Correct or Incorrect
Rewrite the sentence in active voice
Choose the best synonym for an italicized word
Compare two statements and pick the more detailed one
Which sentence is grammatically Correct under standard written English used on MCOLES Grammar items?
The officer's remarks about the timeline was confusing.
If the suspect was still hiding, we would have found him by now. (purely hypothetical meaning)
The officer's remarks about the timeline were confusing.
There's several vehicles blocking the intersection.
What does MCOLES currently publish about the Grammar category's share of the test?
Exactly 4%
Exactly 14%
Exactly 50%
No current category item count or weight is published
You see: "A list of stolen items were recovered from the vehicle." What is the best first scan step, and what judgment follows?
Trust that items is the subject and mark Correct
Check apostrophes first and mark Incorrect for punctuation
Ignore the sentence because lists are always plural
Identify list as the singular subject; were disagrees, so mark Incorrect
Sections you finish are checked off in the contents.
