When I google "I have been admitted to" I get a few hits such as the following:
"I have been admitted to the Institute for Orthodox Christian Studies."
"I have been admitted to the economics PhD programme at Boston College."
Still, I don't get more than a few relevant hits on UK pages, and I get no hits at all when I google "I have been admitted to a course" and "I have been admitted to the university". Consequently, I suspect that in English you use a different verb for this, instead of "admit", but I can't think of what this would be.
So, now my question is: what would be the appropriate way to say that the university has accepted my application for a course or programme?
