I notice there have been some similar questions, like Will turn down a graduate (Master's) program have effect on my application for the same program?. But my situation is a little bit different.
I once turned down a Master in statistics admission at University A and accept another Master in applied mathematics at University B. At that time, I think the Master program at University A focus more on the applied statistics but I want to learn more math and theoretical statistics to prepare for applying for statistics PhD program. So I accept the applied math master program at University B.
I plan to apply for statistics PhD program at University A this fall.
Question 1
Will I be put into a less favorable place compared to other applicants because of this?
Question 2
Should I mention that I once turned down the master's admission?
