I did the online test back in November 2013, and there was definitely a spatial visualisation in there. It was the second last section before the "what would you do" questions.
For me it was the hardest part.
I also got the did not meet requirements email after it.
I'm going to give it another crack at the end of the year.
All I can say with the online assessment, don't do what I did. It says it should take 90 minutes. I felt I had to do it in that time, and so didn't pause between the sections.
As long as you stay logged in, take a couple of minutes between the sections. Some of the sections get you quite wound up.
