Question for students in the TUI PhD that have completed a TUI MBA/MS.

I am in the MS-ITM program and have completed 3 classes. I have gotten mostly A's and A-'s and three B+'s because I got way off track with my paper.

I am thinking about the PhD in BA program and was wondering how the quality of work that needs to be submitted for the PhD program compares to the quality of work that needs to be submitted for the MS program.

I don't want to start a PhD program and find out that the work I am submitting is not good enough. Any feedback would be great.
