Dear SirJ,
and if some people during the test done was worried?
Did you know that Einstein too wasn't selected for a place in the University of Zurigo, with a selection test?
Simply I think that the exam went bad, also for me, because maybe I wasn't prepared enough or I was too worried, or other people was more lucky than me during the test.......stop.
It was a chance, I didn't get it but I continue to live with a smile on the mouth, because in the life of a person a test represent only a chance, nothing else.
But probably I'm writing to a troll, or, worse, to a candidate that received the maybe-email and now he's thinking a little like a poor moron.
Good luck for the people invited at the second stage.
