Hi 

According to the mark you said it is actually not possible to get seat in govt college or govt quota private college 

 the previous year neet cutoff is 595 for oc ,588 for obc , 568 for mbc (note : it is the rough estimation neet cutoff of previous year also it varies according to the state )

So take a year and write the next year exam or you can take other paramedical courses like psychology, physiology etc 

All the best
