Hi Gayathri,
The admissions to all law colleges in India are based on entrance exam (as per bar council's guidelines). You have to appear for Register for entrance and appear for the exam. All the National Law University's admissions are based on CLAT score. Top private colleges accept ISAT Scores. CLAT & ISAT exams are over already. If you have not appeared for any entrance - then no chance in getting admission in government law colleges. However, almost all the private colleges conduct their own entrance exams as well. The registrations are still on.
