You won't be able to get a medical seat in the same year if you are not able to qualify The NEET exam.

You can give another attempt if you believe that you won't be able to clear it in the first try. 

Good luck 

Hello,

Yes you can take admission in a medical college without dropping an year but the colleges that you will get would be all private colleges. you can get admission in them through their entrance tests or through your board examination marks. Some of the colleges also have direct admission processes. hence you can try for them too. 

Hope it helps
