I'm in open category, I have got 54% in 12th sci, In Grouping (Phy,chem,Bio= 143) so I'm qualify in neet exam

Hello

Neet eligibility  criteria says that,
to be eligible  you must have passed your 12th with English and PCB (pass 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 40% in aggregate of PCB if belongs to Obc/ Sc /st .

So , being from general category you need at least 50% aggregate in PCB to be eligible

Now,
Your aggregate in PCB is

= 143
=(143/300*100 )%
=47.6% i.e lesser than 50% , so you don't fulfil above aforesaid % requirement and thus you are not eligible for neet examination
