Gents, My questions may seem trivial but the answers I found in the internet are contradictory,so I decided to ask them here since this forum is a trustworthy source for me. First,I wanna say that personally I'm interested in Ph.D programs in Electriclal&Electroincs Engineering and Applied Physics,so please assume that my questions are related to these fields. As I read,nowadays the duration of studying on Ph.D programs is about 6 years or even more.Are there any realistic possibilities to shorten the time of getting Ph.D?Because I've read that this period(6 years or more) is needed to the university because of profit reasons(I mean,to extract from graduate students as much use as possible).So,is it realistic to get a Ph.D after,say,3 years in case of hard-working,of course? You might say that the one pursuing Ph.D is supposed to be enjoyed with a research in general.Yes,I agree with you but the reason why I'm asking this is totally pragmatic. First,many write the amount of a typical scholarship is not that big(btw,how much is it nowadays?I found different numbers). Second,the less the duration of Ph.D program is the earlier you're able to move to the next step of your desired career.It's obvious. Btw,could you tell me,please if all Ph.D programs(at least for EE and Physics) are free of charge and provide a scholarship or not? Thanks!
