I have got the less than 50 percent marks in bcom so am i eligible for the exam of l.l.b??

There is no common entrance exam for LLB programme, If you want to know about AILET then the exam is conducted for five-year integrated law programme and LLM (Postgraduate) programmes only. Generally the universities for LLB programme require minimum 50% in Graduation but as you told that you have less than 50% in your Graduation then you can go for Symbiosis Law Pune, To get admission there you should have minimum 45% marks (40% for S.C. /S.T.) in one attempt (No Compartment). You can check the complete detail with the given below link.

Good Luck!

All LLB exams generally shall need minimum 50%aggregate marks in graduation to be eligible for LLb course.

For exams like cLAT and AILeT Yyou will need minimum 55%aggregate marks if in General category and hence you shall not be eligible unfortunately.
