Heya,
I have just called Sarah Petty on the admissions team at Bournemouth in light of the concerns you have raised. She was very confused as to there you are getting this information from. Bournemouth are still interviewing for this course and have 2 more interview days to take place before they will proceed to make their final decisions. Offers were made before xmas but none have been made since, as they are waiting till they have seen everyone, which seems fair as it means late applicants don't miss out!
Sarah advised that they offer 50 places to allow for those that will not accept (due to offers elsewhere etc) but they do not operate a reserve system and never have.
She has also said that if any of us have any questions or concerns, then to call the admissions team. They always answer the phone and are very helpful.... I should know, I have called often enough!
Making accusations as you have, purely based on assumption is really damaging and can cause unnecessary worry to other applicants reading this thread. You certainly did me! Your concerns could easily have been put to bed if you had simply called Sarah, and asked for the truth.
