Youngeconomist, I was in almost exactly the same position as you. I had an econ major and math minor when I came to UVA.

The work is certainly manageable, but be prepared to spend more time and effort on it than anything you did as an undergraduate. At first, myself and other students without their masters were definitely a step behind those with masters. This is simply how it is, since most of the material at the beginning is review to them, and the rigor is new to you. In the first semester, I was more towards the bottom half of the distribution as far as grades go.

By the spring however, it seemed that the work was paying off. Things started clicking, and I was able to start getting grades at the higher end of the distribution, including the top of the distribution in some classes. As I have been preparing for my core exams which are in a couple days, I realize how much I have learned, as asquare said, and how much it makes sense now. In fact, students that seemed to know the material well at the beginning of the year will now come ask me and the younger students for advice.

So don't think its not manageable.... it definitely is, but you really have to want it.
