Divya, to be eligible for NEET, you should have studied Physics, Chemistry, Biology and English as your mandatory subjects. Now you can also study Biology as an additional subject and be eligible for NEET. So you should complete your 12th, pass in all subjects, take up Biology as an additional subject from NIOS and secure a minimum aggregate of 50% in Physics, Chemistry and Biology. Now it is 50% for General Category, 45% for PWD and 40% for OBC,SC,ST. If you fulfil this criteria, you are eligible for NEET.

Hello student I'm sorry to inform you but no you can't eligible to appear in Neet entrance examination as you didn't ful fill the eligibility criteria which says - Candidates must passed or appearing class 12 with physics chemistry and biology with minimum 50 percent marks from a recognized board.

However if you want to appear in neet you can appear for NIOS on demand examination and then apply for NEET Nios is a recognized board and valid for neet entrance examination.

Feel free to comment if you have any doubt

Good luck
