Dear Ramana, for joining MBBS as a course, you need to have Physics, Chemistry  Biology/Biotechnology as core subjects in 10+2. For General Category students, the minimum aggregate needs to be 50% and for Reserved categories like SC/ST it is 45% and for PWD it is 40%. With this as your highest qualification you need to appear for NEET for admission into Medical colleges across India. The other 2 entrance examinations for MBBS are JIPMER and AIIMS MBBS. While the educational qualification remains the same, the minimum aggregate slightly alters. And you need to be atleast 17 years old by December 31st of the year of admission.
