Dear Jayasudha,

For admission to MBBS you have to appear in either NEET (National Eligibility cum Entrance Test) , AIIMS - MBBS entrance (All India Institute of Medical Sciences - MBBS entrance) or Jawaharlal Institute of Postgraduate Medical Education & Research MBBS Entrance Exam (JIPMER MBBS). These exams are held across the country. So if you are aiming for 2019. You need to appear in the entrance exams for the same. The last date for filling up the form for NEET 2019 is 7th December 2012. For AIIMS - the basic registration is in progress and the last date is January 3, 2019. For JIPMER entrance exam, the call for filling up the application form is 6th March 2019.
