Do not submit a section while time remains. Use leftover minutes on flagged items, then on unanswered ones. Format choice is in digital or paper.
Review is still time on the clock
Open the review list and walk unanswered, then flagged, in the review screen. Flagging during the section is in flagging questions.
Tools stay available until you submit, in the tools menu.
The bottom line
Time left is still test time. Submit only when the clock forces you.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
