LLB

Hi Prasad,
LLB and MBA are two very different career options that cannot be compared. It completely depends on what interests you more. I suggest you to speak to someone, who is a lawyer and is working or practicing right now and also speak to someone, who is an industry professional after MBA in finance. This way you will get a perspective because job scope is good in both courses, if you pursue from good colleges.

Top colleges accepting LSAT scores are Christ College of Law, Bharati Vidyapeeth's New Law College, Faculty of Law, BHU, UPES Dehradun. All of these are pretty reputed for integrated law programs but if you've any inclination towards core domain, then, do consider UPES as it offers specialized integrated programs in core domain. So, you would be having an added advantage to get in to core domain as well after completion of your course. So choose wisely and take your pick.
Good luck.

It is not a bad choice choosing English. But, a lawyer, if he settles in the profession, can earn more and become more famous.

This is like comparing oranges with apples. You should first decide which course you want to pursue.
As far as PGP of IIM Kozhikode is concerned, it is well reputed and would be ranked around 6-7th in India.

You can enroll yourself for 3 Year LLB courses at Law colleges that offer the program like:
1. Government Law College – Mumbai.
2. Jamia Millia Islamia - New Delhi.
3. Indian Law School – Pune.
4. Delhi University - New Delhi and various other State Universities.
You may enroll yourself in Evening Courses (Delhi University offers one) while working at your firm during the day. The course isn't that difficult for I know someone who worked during the day at law firms, to get a hands-on experience, while pursuing his 3 year course in the evening. Once graduated, you are at par with any graduate of law and eligible to practice law.

Complete your B.Com and then go for three year LLB course from some reputed institution. It will be better for your career as your courses in B.Com will help you get a better understanding of commercial, business and trade related laws.
