The GRE is roughly four hours long (including breaks), and is divided into seven sections. The first two sections are always essay prompts, while the next five sections are 20-question verbal and quantitative problem sets. The first section after the essays will be randomly determined, and the sections will alternate thereafter. This means that there will be three of whichever section is randomly selected, and one of these three sections will be the unscored research section.
Students receive a 10-minute break after the fourth section, and 1-minute breaks between all the others.
