Hello mizpahel

Presently the only way to  get admission in colleges with  Doctorate of Medicine (MD) courses in Aerospace Medicine is by giving the  National level medical entrance examination (NEET PG ) and you have to qualify the points mentioned below

• All the eligible participants need to qualify the MBBS course from an Indian recognized university with minimum aggregate scores of 55%.
• Candidates have to acquire a provisional or permanent registrations certificate issued by the State Medical Council.
