Verb Tense, Form, and Logical Sequence
SAT Reading & WritingStandard English ConventionsMedium
Use time clues and surrounding verbs to choose the form that expresses the intended sequence.
What you need to know
- Maintain tense unless the timeline genuinely changes.
- Past perfect marks an earlier past action when that distinction matters.
- Participles require helping verbs: has written, was discovered.
- Infinitive and gerund forms depend on sentence structure and idiom.
The AYLOTI method
- Mark time words and dates.
- Place the actions on a timeline.
- Match surrounding tense unless sequence requires a shift.
- Check that the selected form completes the verb phrase.

Worked example
By the time the report appeared in 2020, researchers ___ the samples for three years. Choose studied or had studied.
- Report appeared in the past.
- Study began earlier and was completed/ongoing before that past point.
- Past perfect clearly marks the earlier action.
Answer: “Had studied.”
Common SAT traps
- Switching tense because an answer sounds formal.
- Using a participle without a helping verb.
- Using past perfect when ordinary chronological order is already clear and no earlier-past emphasis is needed.
Quick check
Choose: “Since 2022, the team has recorded/recorded 40 events.”
“Has recorded,” because since connects past beginning to the present.
Before you move on
- Explain the core rule without looking back.
- Redo the worked example using your own steps.
- Write the trap you are most likely to fall for.
