'whitelighter': Give HR a call. That's quite a long time they've kept you waiting, I have to admit.
'1mag1n3': You mentioned you did a mathematics paper? Sounds like they might have brought that back in then. Back in 2006 it was 4 tests in total; Spatial Reasoning, Diagramming, Basic Checking and Basic Arithmetic. In addition there was the Motivational Paper and the (then) 240 question paper-based OPQ.
Although things change a lot these days it seems. I wouldn't be surprised if they alternate the Basic Arithmetic test with the Basic Checking test.
Best advice is to cover all bases by doing thorough preparation in all areas!
