GRE stands for Graduate Record Examination. It is a standardized test used by many graduate schools and business schools in English-speaking countries as part of their admission process. The test is designed to assess a student's readiness for graduate-level studies and measures verbal reasoning, quantitative reasoning, and analytical writing skills.

The GRE is a computer-based test that is administered at testing centres around the world. The test takes about three and a half hours to complete and includes multiple-choice questions and essay writing. The verbal and quantitative reasoning sections are scored on a scale of 130-170, in one-point increments, while the analytical writing section is scored on a scale of 0-6, in half-point increments.

Preparing for the GRE typically involves studying basic math concepts, developing verbal reasoning skills, and practicing writing analytical essays. Many test-takers also work on time management and test-taking strategies to improve their overall performance on the exam. There are many resources available to help students prepare for the GRE, including practice tests, study guides, and online courses.
