The GRE (Graduate Record Examination) is a standardized test commonly required for admission to many graduate schools in the United States, Canada, and some other countries. It is designed to measure skills important for success in graduate-level academic work. The test assesses:

• Verbal reasoning: understanding and evaluating written material, analyzing relationships between parts of sentences, drawing conclusions.
• Quantitative reasoning: problem-solving using algebra, geometry, arithmetic, and data analysis.
• Analytical writing: critical thinking and the ability to articulate complex ideas effectively.

The GRE General Test is usually computer-based and consists of six sections: one analytical writing section, two verbal reasoning sections, two quantitative reasoning sections, and one unscored or research section. The entire test lasts about 3 hours and 45 minutes. Scores for verbal and quantitative reasoning range from 130 to 170 each, and the analytical writing section is scored from 0 to 6. The combined verbal and quantitative scores range from 260 to 340. The test fee is generally around $205. The GRE is used by graduate, business, and law schools as a standardized measure to compare applicants' qualifications and preparedness for graduate study. Its importance in admissions can vary by school and program. There are also GRE Subject Tests for specific fields like mathematics, physics, and psychology, which test knowledge in those disciplines. In summary, the GRE is a comprehensive exam designed to evaluate critical thinking, analytical writing, quantitative and verbal reasoning skills necessary for success in graduate education. It is a key component of the admissions process for many advanced degree programs. Let me know if you want more details about the test format, scoring, or preparation.
