Lots of people take two courses at once. Those of us doing grad school through student loans have to take at least two at a time to qualify for financial aid. Three, on the other hand, would be a lot. __________________________ links deleted by moderator
It depends how much you know about the subject - when I took my graduate degrees I was working 6-days a week with long hours of work and commute. When I took more than one course I took one easy and one difficult course. In both degrees the theses were not hard but they took a lot of time (for one I traveled to the UK to do rearch a few times using vacation time).
Actually you can take one graduate course per semester and still qualify for student loans at APU/AMU...
I am a current AMU grad student, and this is true. One graduate course per 16-week semester is considered half-time, which is the minimum for FSA. See link: Enrollment Status
