Llb coursr for practising ca

I AM PRACTISING CA PRACTISING SINCE LAST 9 YEARS. MY EMPHAISIS IS ON SALES TAX PRACTICE THOUGH I   AM ALSO INVOLVED IN INCOME TAX COMPLIANCE. I AM INTENDING TO PURSUE LLB NOW TO GET  KNOWLEDGE ABOUT FUNDAMENTALS OF LAW LIKE CONSTITUTION, LAW OF EVIDENCE, CIVIL PROCDURE CODE, JURISPRUDENCE ETC. I AM OF OPINION THAT IT WILL HELP IN BETTER INTERPRETTATION. MY SENIOR ARE OF OPINION THAT ALL THESE THINGS CAN BE STUDIED EVEN BY PURCHASING BOOKS AND READING, THERE IS NO NEED TO DO LLB FOR THAT. PLEASE GUIDE.
