there is a forum on them somewhere already, I put my experience of Malgus on and some others seem to have had similar experiences.
I don't want to put you off but don't expect very much - like to hear your results when they say you will or to get any feedback. Any time scale they might give should be doubled at least! Sorry to be negative but I think its a bit of a scam.
Take a look at the website for Saville & Holdsworth or SHL (not sure what they go under) - they are the tests you will take and there are some sample ones you can do on their website. You have to do a numerical comprehension one, a verbal comprehension one and a pattern recognition one.
What they were offering all sounded too good to be true. I think they have changed the offer now though.
Sorry to sound negative.
Good luck
