12th(BSEB) marks in phy 49 mark(theory 24 &practical 25)Che 56(theory30 &practical 26) bio48(theory24practical 24)am I eligible for NEET ?

Dear Deshraj, based upon the marks, your aggregate is 51%. And that qualifies for the minimum required aggregate. However,  you need to check if you have cleared the theory because your marks are lesser. If you have cleared the theory exams and your aggregate in these subjects is 50%, then you qualify for NEET. If you haven't cleared your Board theory exams, though you have scored the required aggregate, you cannot appear for NEET.
