Ok. Regular course is funded by the government where university doesn't has to put into it's own money to teach you and provide you with other facilities, such as, hostel, mess, library, societies and all. But in a self-financed course these all are provided to you by the "University" not government's funding. 

That's why the fees for self-finance is more. 

Hello Nagesh Pal Singh

The only difference is of fees structure, rest all is same for all the candidates. They sit in the same class and appear in the same examination.
