I'm currently enrolled in a PhD program in the US. Before picking up my master's degree, I'll be applying to a different PhD program that's more suited to my interests. I will be able to get two letters of recommendations from my undergraduate university and one letter of recommendation from my current graduate institution. Does this combination seem all right? If possible, I can get a second letter from my current graduate intuition as well, but I suspect that letter won't be very strong due to my not having done a lot of work with that faculty member.
Does this combination look all right?
