With 455 NEET score and being from Karnataka, getting an MBBS seat in Goa Medical College under government quota is highly unlikely, as domicile rules apply. You may explore private Karnataka colleges or other state private options.

With NEET, score of 455 were all in their rank is likely above one lakh which is far from the closing air rank of 6700 to 16000 for Goa medical College under the 15 percentage all India quota.

Karnataka student, you are not eligible for Goa 85% quota because it’s reserved for Goa domiciled applicants  only.

So unfortunately, with a 455 score and without a Goa domicile, you are very unlikely to secure an MBBS seat at Goa medical College for the 2025 to 26 session .
