There are no secrets. Stop whipping this idea up. If applicants go to Open Days and listen to subject presentations/ask questions, if they read the full course description etc (and not just the first page), and if they read the published Admissions Statement for that course and/or Uni, they will have a clear idea of what is required. Please - there is enough of this 'Only I know this' cobblers on TSR already. Unis don't do 'secrets'.
But did you bother to watch?
