It is absolutely not possible to pursue PhD without a degree course.

Dear Bhavika Waghela,
It depends entirely from one university to another. Some universities seek M.Phil admission first and later on the basis of M.Phil they provide admission into Ph.D. Some universities provide direct admission based on entrance tests or based on NET/SET examinations. Coming to business schools, they do not provide Ph.D degree but provide equivalent degrees like, FPM. All the best.

It ranges between 7 and 9 for different teachers.
All are Ph.D holders.

Deccan College-Postgraduate College and Maharashtra Institute of Technology offer Ph.D course. You need to qualify the entrance exam to get admission in the same.

Hi Harshadeep,
Do you mean Banaras Hindu University? If yes, they won't provide you a scholarship for your Ph.D. abroad. The university abroad, Aberdeen University in this case will have Ph.Ds. funding options, you should check with the university itself.
