hey Shrutismita , these marks are very less to secure a goverment seat in any college for mbbs .And if we talk about Assam colleges ,there are a total of 6 govt. medical colleges and considering previous year cutoff ,the cutoff for sc candidate was 410 marks ,so you can imagine a general candidate's cutoff.And this year the cutoff went high so the Cutoff of Sc as well as for general candidate would also increase, so you will have hard getting any goverment college.
