Lavanya, to appear for NEET you should have completed 10+2 with Physics, Chemistry and Biology with a minimum aggregate of 50%. It is 50% for General Category, 45% for PWD and 40% for OBC,SC,ST. Now if you haven't studied Biology as a core subject, you can study Biology as an additional subject as well. You can join NIOS for that. Please check with the nearest NIOS study centre if you still have time to study Biology this year. That is the only way out. Or else, you have to wait until the next year to study Biology through NIOS and appear for NEET.

If you are interested in medicine, then you've to get back to Biology because Biology is the background of medicine. You can think of taking a drop as well if you feel it's too late and you cannot crack neet this year because you are so interested in Medical, then don't hesitate to take a drop instead of getting into some wrong course which you regret after years.

Thank you.
