hey 

she might get govt medical college in karnataka with 350 marks and belonging to obc category only under state quota. we are predicting cut off on the basis of previopus year cut off. as per previous year the minimum cut off of karnataka for obc category under state quota was 338 marks pof raichur institute of medical sciences in raichur. and under all india quota the cut off was more than 540 marks. we are not sure about this year cut off as it changes every year depending on no.of candidates, no.of seats and difficulty of exam. so hope for better result. 

here is a link which has govt colleges in karnataka with their previous year cut off. i hope this might help you https://medicine.careers360.com/articles/neet-cutoff-karnataka
