Hello I am a graduate student, with a masters degree in physics but with no impressive marks so far. I am looking for a PhD position in the UK, so far without success. My question is If Supervisors prefere students who are self funded or students who are funded by the university ? Can anyone explain to me the Supervisor's point of view.Do they actually are trying to get as less PhD students as possible, ? Do they have any personal advantage taking self funded students or funded by the University students? I have dicussed the issue with many possible supervisors but I have the impression that i am missing a well kept secret. If anyone is actually working in an institution and can speak openly about some secrets , I would appreciate very much the reply.
