Hello

You need to consider your percentage in aggregate of PCB and not individually in each of PCB .

This is because,

Neet eligibility  criteria says that,
to be eligible  you must have passed your 12th with English and PCB (in both the theory and practical)  with at least 50 % in aggregate of PCB ( in theory +practical) in 12th examination  if you belong to general category , or  at least  45% in aggregate of PCB if belongs to ph category or at least 40% in aggregate of PCB if belongs to Obc/ Sc /st

For detailed information about neet examination go through our page for which link is provided below; -
