Dear Arya, the online applications for JIPMER B.Sc entrance exam were supposed to be started on April 18th at their official website jipmer.puducherry.gov.in. However, the link hasn't been activated yet. And there has been no official notification in this regards. Even if the applications have been released which doesnt seem like the case,  the last date is May 24th so do not worry but give it some time.
