Once you enroll yourself for any law course with KSLU, you will have to complete the course within the prescribed time by the university. 

For example, if you are in the 3 years course of LLB then you will be given +3 years to finish the course (i.e, 3+3). If you surpass the time you will have to enroll for the fresh batch.

Otherwise, you can also keep the course going and be enrolled, take a year's break, and get back. But it is difficult to catch up with the academics considering a break since they take time to follow up. 

Also, it is heard in rumors that KSLUs evaluation system is unfair and has left students in much agony.
