Each country may have its own specific exam, such as the MCAT in the United States or the NEET in India. Success in these exams is crucial, as they often determine a student's eligibility for medical programs. Preparation typically involves extensive study and practice, as competition can be intense. Scoring well can open doors to prestigious medical institutions and ultimately lead to a career in healthcare.
