I was browsing through Academia SE and found this question.
To save you from reading the whole thing, here is what confused me: the person who asked a question is in Master program at university, but the top answering person (with high reputation) asked them "By the way, do you mind my asking, why aren't you in a PhD program? In physics it seems a bit unusual to be in a Master's only program."
Maybe I got something wrong, but does this person mean that you could be in the Master AND in PhD program at the same time? How is it possible? I am going to apply to a Master program next year and all universities without exception require finished Master degree in order to apply for PhD program. I always thought that the process is the same worldwide, i.e. Bachelor -> Master -> PhD
