After this you will get college for mbbs only on the basis of neet rank. Even if you get same score , you don't need to worry because you will be selected on the basis of your NEET rank which unique to every candidate.

They award rank on few criteria serially below

1. Marks in biology.
2. Marks in chemistry.
3. Least no. Of negative marks in exam.
4. Candidate with older age would be preferred.

So work hard for NEET.

hope this will help

all the best for your future!!!!!!!!!!!!!
