Competitive exams are standardized tests designed to assess a candidate's knowledge, skills, and abilities in specific subjects. These exams are often used for admission into educational institutions, selection for jobs, or placement in professional courses. Examples include the SAT for college admissions, the GRE for graduate schools, and various civil service exams for government jobs. These exams typically feature multiple-choice questions, essays, or problem-solving tasks, and they are scored to rank candidates against one another. Preparation for competitive exams often involves studying specific subjects, practicing past papers, and taking mock tests to improve performance and increase chances of success.
