I went through stage 1 both last year and this year, both times in Glasgow. Last year there was a numerical reasoning test, this year there wasn't.
Tests that I took this year were...
Motivation Paper
Diagramming
Spatial Awareness
Basic Checking
And also a "learning styles" questionaire.
Last year there was also a personality questionaire that has now been changed to an online personality test should you be clever enough to pass stage 1.
This is why stage 1 is now only half a day. Last year it was a full day.
