You what???!

Weird headline - "Nobel peace prize winner Malala Yousafzai graduates high school...". You may remember that this was the young girl who was shot in the head by the Taliban in Pakistan for daring to campaign for education for girls.  She was brought over here - to Birmingham - for treatment, and then stayed on here to go to school. She is presently awaiting her A-level results and has been offered a place at Oxford. So... we don't have high schools - they are secondary schools - and we only "graduate" from University.  Whether the headline was written by, or for, the American market I don't know, but to us it makes no sense.
