Based on your NEET rank of 725866 and general category rank of 218983, you can try for some deemed medical colleges under the All India Quota in MCC counselling. Your preferred region is northern India, but most deemed colleges in northern states close at better ranks than yours. Still, there are a few options that might be available to you in choice filling.

Here are some deemed colleges where the closing rank last year was higher than your rank, so you may have a chance:

Shri Satya Sai Medical College and Research Institute in Kanchipuram had closing rank around 1332973
SBKS Medical Institute and Research Centre in Vadodara had closing rank around 596197
Yenepoya Medical College in Mangalore under Muslim minority quota had closing rank around 402577
Manipal Tata Medical College in Jamshedpur had closing rank around 82158
Amrita School of Medicine in Faridabad had closing rank around 286837

Top deemed colleges like KMC Manipal, KMC Mangalore, Hamdard Institute in Delhi, and Symbiosis Medical College in Pune had closing ranks around 50000 to 65000. These are out of reach at your rank.

So you can consider filling these five colleges in your MCC counselling choice list. These are not all in northern states, but they are among the very few that accepted students with higher ranks.

Also keep in mind that deemed colleges have high fees, usually between Rs 15 lakh to Rs 25 lakh per year. You should check the latest fee and cut-off details on the official MCC website.
