First of all, there is no minimum marks to be secured to enter JIPMER it is purely based on the merit you’ve to top the list to enter into JIPMER. It is also based on the category and Domicile (State) you belong.

It really depends on how the Question paper was set. If you found the paper to be easy, then you surely have to get around 170+ in order to get a seat during the first interview itself. On an average it has been observed to be more than 150-160+ for any chance into JIPMER.

Best of luck !
