Law

For LLB or any law course, you require a Bachelor's degree in any subject.

From which city or state you want to pursue this course?

You can write directly to IIM-Lucknow on their Id or can contact them, but I will advise you to not to take any illegal action because it will ultimately harm you because IIM is a big autonomous body, you shouldn't do any offensive thing against them.

Bachelors in design in footwear is a rare course and the earning potential for a footwear designer is very less. About LLB, it's not a good field as of now. A lot of advocates are working under the famous practitioners. This practice will be for a long-term and your life will not get settled soon. If you are planning for a secure and easy switching possibility, you can select BBA. BBA graduates are required everywhere in almost all companies.

I am not sure of the Diploma on this. Kindly check distance education department's website and call on the number provided on the website for details.

No, there is no other exam for admission to NLSIU after cracking CLAT.

The LLB degree requires you to have already completed an undergraduate degree of at least three years. As the LLB degree is itself three years long, this would require students to spend six years to get a law degree. The BA LLB/BBA LLB/B.Sc LLB degree offered by most law schools take five years to complete, so students who opt for it save on a year of studying which, believe me, is a big thing. However, I suspect there is an additional reason the NLUs do not offer the 3-year BA degree.
