Make an informed career choice, ask the expert now!.) i wanna do MBA without any work experience . is it good idea ?

Yes kuldeep its good to gain degree before entering industry. your base is stronger in terms of knowledge. Earlier students used to join MBA/PGDM just after graduation. they had no exposure of real working conditions or how industry works. hence it was difficult to co-relate to the subjects taught.

the most paying combination i think would be Btech /Mtech. While doing Mtech u are also given part time job in the campus from where you are studying and afterwards also jobs are good. MBA is also not bad, Best would be to check some sites and decide like liba, lpu, srm
