hey ashwin

you can get admission in govt medical college under all india in karnataka with 485 marks only if you belong to sc or st categpry. as per previous year trend for general categpry under all india quota was above 542 marks. and for sc and st category the minimum cut off was 402. we are not sure about this year cut off as it changes every year depending upon number of candidates, no.of seats and difficulty of exam. so hope for better result.

here is a link with all the medical colleges of karnataka as well as their cut off. i hope this might help you https://medicine.careers360.com/articles/neet-cutoff-karnataka
