Hello,
.
Are you talking about NEET examination or  JEE examination?
.
If you are talking about any if the Examination then no sorry, for getting a seat government college you need atleast score of 650+ and yeah it even depends on the  college cutoffs/ state as well as category.
.
So, first do select the college and then check out its eligibility criteria. Because all the college have different cut-offs. Select few colleges and check out its details. You will clear your point
