IOM ENTRANCE EXAM SYLLABUS FOR MBBS
IOM (Institute of Medicine) offers five and half years MBBS program in Nepal which includes one year internship. However, it takes around 6 years to complete the course. The seat is limited to take part in MBBS program as IOM admits only 43 Nepalese students and foreigners as pass the criteria met by IOM. Due to the limitation, all students must take part in the entrance examination prior to selection for the course. Here you can find the marks distribution for IOM MBBS Entrance Exam and the syllabus for it.
