Dear Mokita, 

Congratulation first of all for getting 525 in neet 2019.You have very less chance of getting a government college is Delhi but tere are high chances of you getting a seat in haryana.

I am providing the cut off of some colleges of haryana for your reference:-

ESIC FARIDABAD-535

KALPNA CHAWLA GMC,KARNAL-547

SHAHEED HASAN KHAN MEWATI GMC,NALHAR-531

BPS GMC FOR WOMEN,SONEPAT -535

PT.DAYAL SHARMA POST GRADUATE INSTITUTE OF MEDICAL SCIENCE, ROHTAK-486

These are neet 2018 general category cut off which may change this year but you will surely have a chance in one if these.

Government colleges of Delhi have a cut off of around 570-600 marks so according to me you admission there is very difficult. But you should try your luck as one college of Delhi was UNIVERSITY COLLEGE OF MEDICAL SCIENCE  AND GTB HOSPITAL with cut off of 510.

Rest all colleges were above 565.All the best!!
