To be eligible for JIPMER you need to pass PCB and English subject in your 12th boards or equivalent, individually. Other than that if you belong to the ‘General’ category, you must have scored at least 60% aggregate in PCB totally.
Considering that your aggregate in PCB is 59.8% which is less than 60% you are not eligible. There is no scope of rounding off for calculating the eligiblity criteria.
Best of luck!
