Hi, 

298 is really less for a good government college this year. I don't want to break your heart but it is impossible to get mbbs with this score. Even bams cut off are expected to rise seeing today's results. Private college may grant you admission but then again you may not get very good college. So if you are looking for a good college, I will suggest you to start studying again and try to score better than this. This might be heart breaking right now but you can do it. Just keep your spirits high. 

Good luck!
