How much marks should I score in neet exam so that I can get a government medical College seat in Delhi?

see the government medical colleges in Delhi might warranty to get in excess of 550 out of 600 out of 720 to get in through the 85% state quota also sometimes the cutoffs are not below 580 out of 720 so it would do you well to have a target in excess of that range
and if you want to avail the Delhi medical colleges using the 15% all India quota on an unreserved basis then you will definitely have to score in excess of 600 to 620 out of 720

Hii Sushila
As cut-off marks vary year to year depending upon number of students appear in the exam and the difficulty level of the exam so if you belong to general category and if you are applying under 85% state quota seats then to be on safer side you should score above 560 marks to secure a seat in government medical College in delhi.i hope this information helps you.
Thank you
