The GRE adapts by SECTION, not by question. Your performance on the first Verbal section sets the difficulty of the second, and the same for Quant. Two consequences follow, and most students act on neither.
The first section of each type is worth protecting. Not because the questions score more, but because it decides which pool of questions you are allowed to earn marks from. Going in cold, or burning four minutes on question two, costs more here than anywhere else on the test. Warm up before you enter the centre — a few questions on paper in the car park is not superstition, it is the only way the first section is not your warm-up.
Inside a section, you are free. You can answer out of order, flag anything, change answers and review before the section closes. That freedom is the whole pacing strategy: nothing is worth more than anything else, so the optimal order is easy-first. Take one pass answering everything that falls out in under ninety seconds, flag the rest, and spend the remaining time on the flags.
Learn the review screen before test day. It lists every question with its status. Students who meet it for the first time in a live section waste a minute understanding it and often never use it. Whatever tool you practise with, practise flagging and reviewing.
Never leave a blank. There is no penalty for a wrong answer. In the last thirty seconds, answer everything unanswered, including things you have not read.
Know the shape of the sitting. Analytical Writing first, then the Verbal and Quant sections — just under two hours in total. It is short enough that stamina is not the main issue and long enough that a slow start is not recoverable in the same section.
The unscored section. Do not spend any attention hunting for it. Treat every section as scored, because deciding mid-test that one "does not count" is how a real section gets thrown away.
