The Educational Testing Service (ETS) administers the GRE, which is used by many universities worldwide as part of their graduate program admissions process. The GRE lasts for 1 hour and 58 minutes, and it evaluates applicants from various countries in verbal reasoning, quantitative reasoning, and analytical writing sections. Verbal and quantitative reasoning scores range from 130 to 170 scales, while analytical writing scores range from 0 to 6. Candidates can take the test at different locations globally throughout the year, providing them with the flexibility to schedule their exams. The scores remain valid for five years, and candidates can choose to retake the test multiple times if needed.
