Verb tense, pronoun case, and modifiers: keeping verb tense consistent within a passage unless the meaning shifts, choosing subject versus object pronoun case (including who versus whom), and placing modifiers next to the words they describe to avoid misplaced and dangling modifiers, on the Virginia EOC Writing test.

What this skill is asking

Three usage errors complete the grammar set the Virginia EOC Writing test returns to: verb-tense consistency, pronoun case, and modifier placement. Each has a clear rule, which is why the EOC can test them with "which is correct" multiple-choice items and drop-down items, and the same conventions are scored on the Short Paper's Usage and Mechanics domain. The skill is recognizing each error type and knowing the correct form: keep tenses consistent, use subject pronouns as subjects and object pronouns as objects, and place every modifier next to the word it describes. This page covers all three, each with its rule and its typical trap.

Verb-tense consistency

Tenses should stay steady unless the timeline changes.

The check is whether a tense shift reflects a real change in time. "She studied hard and now understands the topic" is fine, because "studied" (past) and "understands" (present) reflect a real move from past effort to present result. But "She studied hard and understands nothing" mixed into a past narrative is usually an error of carelessness. Read the passage's timeline and keep the verbs matched to it, changing tense only with a reason.

Pronoun case: subject versus object

The reliable test for a compound is to drop the other person. "The award was shared between Maria and (I/me)" becomes "shared between... me" when you drop "Maria and", because you would never say "between I." The same drop-test resolves "She and (I/me) went" (you would say "I went," so "She and I"). For who/whom, substitute he/him: if "him" fits, use "whom." These substitution tests turn a confusing case question into a quick check.

Modifiers: place them next to what they describe

Try this

Q1. When should verb tense change within a passage? [Recall]

• Cue. Only when the meaning genuinely requires it, for example moving from a past event to a present general truth or result. An unmotivated jump from one tense to another (within a single timeline) is an error; otherwise keep tense consistent.

Q2. Why is "Walking home, the rain started" a modifier error, and how do you fix it? [Short explanation]

• Cue. "Walking home" should describe a person, but it sits next to "the rain," implying the rain was walking home (a dangling modifier). Fix it by putting the real subject after the phrase: "Walking home, I was caught when the rain started" (or "As I walked home, the rain started").
