IS it entrance test for MBBS is common for AIIMS,JIpmer and others states?. i want to send my daughters for JIPMER coaching at Pondicherry

Presently AIIMS is conducting its separate exam. JIPMER is also having its separate exam. The details of MBBS admission at JIPMER is available at www.jipmer.edu.in/announcements/admission-to-mbbs-course-2016-session/

No, it's not common for all govt and private medical colleges. But from next year onwards there will be a common test for all. For JIPMER they conduct there own exam.
