PART 1: Earlier Completed Action

What Is Happening?

One action happened BEFORE another action.

The SAT often tests whether you notice which event happened first.

What Does This Mean For You?

Action Step

When you see two actions:

Circle the action that happened first.

Ask:

Which event was already finished before the other event occurred?

If one action finished before another action, the earlier action often uses:

• had + verb

(past perfect)

What Should You Look For?

Look for clue words:

• before
• after
• by the time
• already
• previously
• once

These often signal that the SAT wants you to compare two actions.
