Hi

You don't need to stress yourself  as your overall class 12th percentage doesn't matter when it comes to Neet eligibility criteria only your PCB aggregate is taken in account

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

Now,

Your aggregate in PCB is

= 50 % so you fulfill above aforesaid percentage requirement, so you are eligible for Neet examination and thus you are eligible for Neet counselling ,there will be no problem you don't need to worry at all
