Hi, I'm completely new to this community, so please correct me if I'm doing something wrong.
I am applying to several Ph.D. programs in physics, and on every application I am asked to provide details of where else I'm applying to.
Why do they ask me this? As I presume everybody is, I am writing slightly different SOPs for different schools (since some don't have plasma physics but do have my secondary interest), and I was wondering if they were going to share each others' information or something like that (I know in undergrad applications admission officers sometimes share applications).
Any comments on this?
