Online Phd programs provide a great flexibility with your life and schedule.  Making use of the internet allows students time to work at other jobs, handle responsibilities, etc. – all while studying thoroughly to receive their doctorate.  As it goes, many who pursue a Phd end up having to do a residency as part of their studies.  Fortunately, online Phd programs allow these students the comfort of doing at least some of their coursework at home – plus, the lack of a classroom for most of your studies means no worries about summer or holiday breaks; you can work whenever you wish.
