You may know that your CLAT score and rank is low and it bit difficult to get IP law college but you may have some chance so you may apply for that but I also suggested that you may also apply or seek some another college also as you backup plan because of getting BBA LLB is difficult for you.

ALL the best.

According to our prediction, if you have AIR rank 13000,then you wont get any NATIONAL LAW UNIVERSITY

So you have to try for some private colleges

Institute of Law, Nirma University - This private law University is often ranked higher than some of the recently established NLUs.

UPES, Dehradun - Another good law University which boasta of a very good studying environment.

JGLS, Sonepat - If you can afford it, this is the real deal. With facilities from abroad and that too with degrees from Ivy League Colleges, JGLS certainly has a bright future for private (costly) legal education in India.

If further doubts, do comment

I hope this helps
