See marks cannot be predicted so easily as they depend on various factors like number of candidates appearing, exam level difficulty, etc. But i can give you some general idea. Having said this, also notice that from this year, AIIMS JIPMER and other medical entrance examinations are also merged into NEET. So cutoffs might vary even more from this year. But depending upon the state you stay in and the colleges you need, the ccutoffs will be acordingly varying.

So as per the last year analysis, 135 marks was the eligibility cutoff for applying for various medical courses. And in government colleges, the usual cutoff for general category is around 440-460 marks and above.

National Institute of Homeopathy, West Bengal had a cutoff of 538 marks for general category. Maharashtra University of Health Science, Nashik had a cutoff closde to 480 marks.

Accordingly cutoffs will vary from college to college.

So give your best in the NEET exam and try to score around 500 and above marks to ensure your seat in the college you need.
