Diploma

Hello Deepak,
You can get admission in IIT Mumbai. See, diploma is considered as equivalent to 12th. So if you have scored 75% or more in diploma, you are eligible to appear for JEE advanced after of course scoring more than cutoff declared in JEE Mains. If you are appearing for diploma then study so that score minimum requirement. It is understood that for diploma holders cracking JEE Mains is tough but then nothing is impossible in this world.

Today PGDM and MBA is treated as same and same salary is being offered to the candidates but inthe long run, a Degree is considered more important than a Diploma in certain cases. After you join any industry or start job then only your experience matters. Degree and Diploma is considered in starting phase only. If you have option for Degree then you must go for a Degree course.

Dear,
As per your query, you need to get the knowledge of HR policies and management skills. For that, you can think certificate or diploma in human resource from IIM.
They have specialised programme for a working professional to enhance their knowledge and skills.
As I understand, according to your statement, Llaw domain won't solve your purpose.
All the best.
