On computer-delivered IELTS you can usually flag an item for review and return later. Flag is a reminder, not extra time — the clock does not pause. Use it when you have a candidate answer but want a second look, then move. Do not flag every item and hope for a clean sweep in the last three minutes. On paper the nearest habit is a light mark in the margin; you still turn pages by hand. Practise leaving two or three flagged items, not fifteen. We cannot show the official test screen. Practice IELTS is a computer Writing and Reading tool. It is not the official familiarisation test, not a booking page, and not Listening or Speaking.
