Program Expectations and Cost
How Many Courses?
Course requirements depend on the college or university you are enrolling in, but the average is 11-13 courses or 39 credits. You do need to look at requirements carefully because at the PhD level, many universities want their students to at least come to their location for their dissertation.
Your master's degree can also affect how many courses you ultimately take. For example, if your master's degree was in Buisness Administration then you will need to take some English courses to get you ready. However, if you master's degree was in English then you may be able bypass some of those requirements and take fewer courses.
How Much Does It Cost?
Cost depends on the university you choose. Some unviersities (even if they are online) will give discounts to in-state students, so if you find one in your own state that might save you a few dollars. Doctorate courses are generally more expensive then other degree programs. One university stated $1,800 per course. When estimating cost you also need to consider other things such as books, fees, taxes, and transportation costs if you need to attend any required events such as dissertation.
