Dear aspirant,

You have not mentioned any exam name or course name in which you want a free seat in. The marks required for a free seat or a seat with very low tuition fees always vary so much depending on the specific exam, the category of the student, and the college or institution . Generally, achieving a high rank in the entrance exam is very important, as it determines the probability of securing a free seat. So to get a free seat try achieving a very high rank in your chosen entrance exam.

Good luck
