as far as I'm aware most independents don't do 100% scholarships these days. Normally 50% is the absolute maximum, even for a top scholarship. Bursaries may be available for those who can't affort the fees, but that's a different matter. So I wonder if something's got lost in translation or exaggerated by someone. Also, they're not meant to give the results until the formal offer date in late Feb, by agreement with other schools.
