Hello Mousam,
Why does one do Ph.D? It's fundamental to satisfy an urge to do some research in one's chosen field. You are also enriching knowledge besides perhaps opening doors for newer technology.

Not necessary, provided you clear all of them, before graduating and take care you don't have many such backs in future.

Hello, if you have a competitive profile you can avail a scholarship. Normally, applicants are considered for scholarships at the time of application and awarded on merit basis. MS programs generally lead to a Ph.D, whether you want to complete your Ph.D after your MS has to be your sole decision based on your career goals. A few MS programs are such that you have to continue to a Ph.D program after completion of the MS program e.g a couple of programs in Arizona State University.

Hi Lavanya,
Since German universities are highly competitive, you must bring good grades in your B.Tech, above 75% is the least. Work on building your academic profile, research work, publications, etc. Take your IELTS and German language certification. For more information you may check the DAAD website.

Hi Shravya,
That totally depends on your interest. If your interest is in business world then do MBA. You will surely find it easy or If you like science and technology then do MS. There is nothing easy and nothing difficult, that totally depends on the individual's passion.
Always do what you love to do.

You need to take care of certain parameters including faculty members, infrastructure, track record and mode of teaching.
You better ask the students studying there at first and then the college people.
Hope this helps.

Hi Raman, take your GRE. However, you already hold a Masters, admission will be tricky. Since, you are there in US already you can gain information more easily. Check the websites for program specific information and admission requirements. If you are still an international applicant you must follow norms set for internationals otherwise you will apply through the same process and pay the same fee as domestic applicants.
