Hey Pravin,
As your query is not well asked, try asking the query again clearly so that it can be easier for us to answer, still as per I have understood your question, the eligibility criteria for one to do LLB is :

• Candidate must have passed 12th examinations from a recognized institution, school or board
• Candidate must have scored minimum 50% marks (45% for reserved category candidates) in the qualifying examinations.
• The course done just after 12th is Integrated LLB like B.A.LL.B, BB.A.LL.B., B.Com.LL.B., B.Sc.LL.B., B.S.W.LL.B

So You cannot pursue LLB Course after 10th class or during 10th class.
Feel free to ask any doubt!
Good Luck!
