Hello Aspirant.

Getting a free seat won't just only depend on your rank but will also depend on factors like the college you join, any reservation, your family income and etc. For different colleges, the rank and criterias will be different. With a rank of 1243, you might have a chance to get a free seat, provided the other criterias are satisfied.

I would suggest you to contact the college where you are planning to get admission regarding this query of yours for better assistance.

Hope that helped.
