Government Law College Coimbatore

Most of the reputed law colleges conduct their own exam. For example, NLUs ask for CLAT score. NLUD offers admission via AILET, GGSIPU through CET, BHU, and Symbiosis also have their own exams, etc. Since most of the competitive exams are over, you can approach private colleges or check your eligibility for KLEE which is yet to be conducted. You can also complete UG from DU then complete law from DU for which you will have to appear in its entrance exam.
As for the universities taking admissions on the basis of HSEE, you can check it on their respective website.
