One of my friends has recently been admitted to the BHMS course at Parul, so I can clear your doubts.
The general eligibility for the BHMS program is that you have to pass 12th from the science stream, with PCB combo, i.e. Physics, Chemistry and Biology. The general candidates need to have at least 50% of marks in aggregate in 12, and 50 percentile in NEET. The reserved category students need to have at least 40% of marks in 12, and 40 percentile in NEET.
