LLM

You can learn everything from course structure to fees to placement records at www.soauniversity.ac.in
Search for LLM on this official site for best information.

To take admission in LLM, first of all you should have done LLB from. A bar council of India approved institute with minimum 50 percent or higher marks and again, it depends from institute to institute, then you need to appear for entrance examination of respective institute such as Mumbai University (date over), NMIMS , TISS, NLU etc.

Admission with a set of percentage marks cannot be guaranteed. Yes, you stand a chance but then you will have to apply and see. This is because admission also depends upon many of those candidates who initially take admission but then opt out later making the seat vacant.

Bar Council of India does not recognise any distance learning degree and in fact there was long tussle between students and UGC in one side and bar council other side. Bar council has clearly mentioned and specified LLM through distance learning is not eligible for reaching position in bar council approved colleges.
Madurai Kamraj, Pune University and Annamalai offers LLM in distance mode.

Dear,
That totally depends on your caliber and interest area.If your foundation and skills are best in law than you need to pursue your career in same line.
But think for this change only in the final year of graduation or law degree.
Currently, if you are more focus on management level profile than law will not be the best fit.
All the best!
