MabdulD, Mr Reddly, agree with the NU secondary. It wasn't terrible, just very limiting in how you could make yourself stand out. I mean, how do you link anything nonacademic and unique to secondary questions purely about a curriculum?
Duke's was 1) electronic, which means inherent glitches galore and also 2) limited. There were tons of questions, but I was actually quite annoyed at the 'character limit' they had in each embedded Word field... Being longwinded compared to most, I kept bumping up against the edge of the limit and swearing. Then the editing began...
The worst was sitting down with each question and thinking out an answer, then finding you couldn't express yourself completely within their limit. Gah!
Most other secondaries were pretty generic fare. I remember WVU including a 'professionalism' essay question along with a list of (selected) professional traits. Then they wanted me to write an essay describing a situation I found my professionalism tested, and how I dealt with it. None of my other schools touched the idea of professionalism with a stick until my interviews. I wonder if other schools have essays on 'professional attributes?'
