Hi, I am Mechanical Engineering Graduate. i wanna take up LLM instead of LLB as it would save my time. So is it possible anyway ??

Worked for OEM's for almost 3 years and now lost my job for almost 4 months. My dad is practicing Advocate and he is not leaving any stone unturned to convince me to get into his shoes. I consider 3 years llb will be waste of time instead i can do LLM from reputed colleges rite sir..? guide me ASAP
